 \subsubsection{Diagnostic Description}  
   
 In this section we list and describe the diagnostic quantities available within the  
 GCM.  The diagnostics are listed in the order that they appear in the  
 Diagnostic Menu, Section \ref{sec:diagnostics:menu}.  
 In all cases, each diagnostic as currently archived on the output datasets  
 is time-averaged over its diagnostic output frequency:  
   
 \[  
 {\bf DIAGNOSTIC} = {1 \over TTOT} \sum_{t=1}^{t=TTOT} diag(t)  
 \]  
 where $TTOT = {{\bf NQDIAG} \over \Delta t}$, {\bf NQDIAG} is the  
 output frequency of the diagnostic, and $\Delta t$ is  
 the timestep over which the diagnostic is updated.    
   
 {\bf 1)  \underline {UFLUX} Surface Zonal Wind Stress on the Atmosphere ($Newton/m^2$) }  
   
 The zonal wind stress is the turbulent flux of zonal momentum from  
 the surface. See section 3.3 for a description of the surface layer parameterization.  
 \[  
 {\bf UFLUX} =  - \rho C_D W_s u \hspace{1cm}where: \hspace{.2cm}C_D = C^2_u  
 \]  
 where $\rho$ = the atmospheric density at the surface, $C_{D}$ is the surface  
 drag coefficient, $C_u$ is the dimensionless surface exchange coefficient for momentum  
 (see diagnostic number 10), $W_s$ is the magnitude of the surface layer wind, and $u$ is  
 the zonal wind in the lowest model layer.  
 \\  
   
   
 {\bf 2)  \underline {VFLUX} Surface Meridional Wind Stress on the Atmosphere ($Newton/m^2$) }  
   
 The meridional wind stress is the turbulent flux of meridional momentum from  
 the surface. See section 3.3 for a description of the surface layer parameterization.  
 \[  
 {\bf VFLUX} =  - \rho C_D W_s v \hspace{1cm}where: \hspace{.2cm}C_D = C^2_u  
 \]

 drag coefficient, $C_u$ is the dimensionless surface exchange coefficient for momentum  
 (see diagnostic number 10), $W_s$ is the magnitude of the surface layer wind, and $v$ is  
 the meridional wind in the lowest model layer.  
 \\  
   
 {\bf 3)  \underline {HFLUX} Surface Flux of Sensible Heat ($Watts/m^2$) }  
   
 The turbulent flux of sensible heat from the surface to the atmosphere is a function of the  
 gradient of virtual potential temperature and the eddy exchange coefficient:  
 \[  
 {\bf HFLUX} =  P^{\kappa}\rho c_{p} C_{H} W_s (\theta_{surface} - \theta_{Nrphys})  
 \hspace{1cm}where: \hspace{.2cm}C_H = C_u C_t  
 \]  
 where $\rho$ = the atmospheric density at the surface, $c_{p}$ is the specific  
 heat of air, $C_{H}$ is the dimensionless surface heat transfer coefficient, $W_s$ is the  
 magnitude of the surface layer wind, $C_u$ is the dimensionless surface exchange coefficient  
 for momentum (see diagnostic number 10), $C_t$ is the dimensionless surface exchange coefficient  
 for heat and moisture (see diagnostic number 9), and $\theta$ is the potential temperature  
 at the surface and at the bottom model level.  
 \\  
   
   
 {\bf 4)  \underline {EFLUX} Surface Flux of Latent Heat ($Watts/m^2$) }  
   
 The turbulent flux of latent heat from the surface to the atmosphere is a function of the  
 gradient of moisture, the potential evapotranspiration fraction and the eddy exchange coefficient:  
 \[  
 {\bf EFLUX} =  \rho \beta L C_{H} W_s (q_{surface} - q_{Nrphys})  
 \hspace{1cm}where: \hspace{.2cm}C_H = C_u C_t  
 \]  
 where $\rho$ = the atmospheric density at the surface, $\beta$ is the fraction of  
 the potential evapotranspiration actually evaporated, L is the latent  
 heat of evaporation, $C_{H}$ is the dimensionless surface heat transfer coefficient, $W_s$ is the  
 magnitude of the surface layer wind, $C_u$ is the dimensionless surface exchange coefficient

 humidity at the surface and at the bottom model level, respectively.  
 \\  
   
 {\bf 5)  \underline {QICE} Heat Conduction Through Sea Ice ($Watts/m^2$) }  
   
 Over sea ice there is an additional source of energy at the surface due to the heat  
 conduction from the relatively warm ocean through the sea ice. The heat conduction  
 through sea ice represents an additional energy source term for the ground temperature equation.  
   
 \[  
 {\bf QICE} = {C_{ti} \over {H_i}} (T_i-T_g)  
 \]  
   
 where $C_{ti}$ is the thermal conductivity of ice, $H_i$ is the ice thickness, assumed to  
 be $3 \hspace{.1cm} m$ where sea ice is present, $T_i$ is 273 degrees Kelvin, and  
 $T_g$ is the temperature of the sea ice.  
   
 NOTE: QICE is not available through model version 5.3, but is available in subsequent versions.  
 \\  
   
   
 {\bf 6) \underline {RADLWG} Net upward Longwave Flux at the surface ($Watts/m^2$)}  
   
 \begin{eqnarray*}  
 {\bf RADLWG} & =  & F_{LW,Nrphys+1}^{Net} \\  
              & =  & F_{LW,Nrphys+1}^\uparrow - F_{LW,Nrphys+1}^\downarrow  
 \end{eqnarray*}  
 \\  
 where Nrphys+1 indicates the lowest model edge-level, or $p = p_{surf}$.  
 $F_{LW}^\uparrow$ is  
 the upward Longwave flux and $F_{LW}^\downarrow$ is the downward Longwave flux.  
 \\  
   
 {\bf 7) \underline {RADSWG} Net downard shortwave Flux at the surface ($Watts/m^2$)}  
   
 \begin{eqnarray*}  
 {\bf RADSWG} & =  & F_{SW,Nrphys+1}^{Net} \\  
              & =  & F_{SW,Nrphys+1}^\downarrow - F_{SW,Nrphys+1}^\uparrow  
 \end{eqnarray*}  
 \\  
 where Nrphys+1 indicates the lowest model edge-level, or $p = p_{surf}$.  
 $F_{SW}^\downarrow$ is  
 the downward Shortwave flux and $F_{SW}^\uparrow$ is the upward Shortwave flux.  
 \\  
   
   
 \noindent  
 {\bf 8)  \underline {RI} Richardson Number} ($dimensionless$)  
   
 \noindent  
 The non-dimensional stability indicator is the ratio of the buoyancy to the shear:  
 \[  
 {\bf RI} = { { {g \over \theta_v} \pp {\theta_v}{z} } \over { (\pp{u}{z})^2 + (\pp{v}{z})^2 } }  
  =  {  {c_p \pp{\theta_v}{z} \pp{P^ \kappa}{z} } \over { (\pp{u}{z})^2 + (\pp{v}{z})^2 } }  
 \]  
 \\  
 where we used the hydrostatic equation:  
 \[  
 {\pp{\Phi}{P^ \kappa}} = c_p \theta_v  
 \]  
 Negative values indicate unstable buoyancy {\bf{AND}} shear, small positive values ($<0.4$)  
 indicate dominantly unstable shear, and large positive values indicate dominantly stable  
 stratification.  
 \\  
   
 \noindent  
 {\bf 9)  \underline {CT}  Surface Exchange Coefficient for Temperature and Moisture ($dimensionless$) }  
   
 \noindent  
 The surface exchange coefficient is obtained from the similarity functions for the stability  
  dependant flux profile relationships:  
 \[  
 {\bf CT} = -{( {\overline{w^{\prime}\theta^{\prime}}}) \over {u_* \Delta \theta }} =  
 -{( {\overline{w^{\prime}q^{\prime}}}) \over {u_* \Delta q }} =  
 { k \over { (\psi_{h} + \psi_{g}) } }  
 \]  
 where $\psi_h$ is the surface layer non-dimensional temperature change and $\psi_g$ is the  
 viscous sublayer non-dimensional temperature or moisture change:  
 \[  
 \psi_{h} = {\int_{\zeta_{0}}^{\zeta} {\phi_{h} \over \zeta} d \zeta} \hspace{1cm} and  
 \hspace{1cm} \psi_{g} = { 0.55 (Pr^{2/3} - 0.2) \over \nu^{1/2} }  
 (h_{0}u_{*} - h_{0_{ref}}u_{*_{ref}})^{1/2}  
 \]  
 and:  
 $h_{0} = 30z_{0}$ with a maximum value over land of 0.01  
   
 \noindent  
 $\phi_h$ is the similarity function of $\zeta$, which expresses the stability dependance of  
 the temperature and moisture gradients, specified differently for stable and unstable  
 layers according to Helfand and Schubert, 1993. k is the Von Karman constant, $\zeta$ is the  
 non-dimensional stability parameter, Pr is the Prandtl number for air, $\nu$ is the molecular  
 viscosity, $z_{0}$ is the surface roughness length, $u_*$ is the surface stress velocity  
 (see diagnostic number 67), and the subscript ref refers to a reference value.  
 \\  
   
 \noindent  
 {\bf 10)  \underline {CU}  Surface Exchange Coefficient for Momentum ($dimensionless$) }  
   
 \noindent  
 The surface exchange coefficient is obtained from the similarity functions for the stability  
  dependant flux profile relationships:  
 \[  
 {\bf CU} = {u_* \over W_s} = { k \over \psi_{m} }  
 \]  
 where $\psi_m$ is the surface layer non-dimensional wind shear:  
 \[  
 \psi_{m} = {\int_{\zeta_{0}}^{\zeta} {\phi_{m} \over \zeta} d \zeta}  
 \]  
 \noindent  
 $\phi_m$ is the similarity function of $\zeta$, which expresses the stability dependance of  
 the temperature and moisture gradients, specified differently for stable and unstable layers  
 according to Helfand and Schubert, 1993. k is the Von Karman constant, $\zeta$ is the  
 non-dimensional stability parameter, $u_*$ is the surface stress velocity  
 (see diagnostic number 67), and $W_s$ is the magnitude of the surface layer wind.  
 \\  
   
 \noindent  
 {\bf 11)  \underline {ET}  Diffusivity Coefficient for Temperature and Moisture ($m^2/sec$) }  
   
 \noindent  
 In the level 2.5 version of the Mellor-Yamada (1974) hierarchy, the turbulent heat or  
 moisture flux for the atmosphere above the surface layer can be expressed as a turbulent  
 diffusion coefficient $K_h$ times the negative of the gradient of potential temperature  
 or moisture. In the Helfand and Labraga (1988) adaptation of this closure, $K_h$  
 takes the form:  
 \[  
 {\bf ET} = K_h = -{( {\overline{w^{\prime}\theta_v^{\prime}}}) \over {\pp{\theta_v}{z}} }  
  = \left\{ \begin{array}{l@{\quad\mbox{for}\quad}l} q \, \ell \, S_H(G_M,G_H) & \mbox{decaying turbulence}  
 \\ { q^2 \over {q_e} } \, \ell \, S_{H}(G_{M_e},G_{H_e}) & \mbox{growing turbulence} \end{array} \right.  
 \]  
 where $q$ is the turbulent velocity, or $\sqrt{2*turbulent \hspace{.2cm} kinetic \hspace{.2cm}  
 energy}$, $q_e$ is the turbulence velocity derived from the more simple level 2.0 model,  
 which describes equilibrium turbulence, $\ell$ is the master length scale related to the layer  
 depth,  
 $S_H$ is a function of $G_H$ and $G_M$, the dimensionless buoyancy and  
 wind shear parameters, respectively, or a function of $G_{H_e}$ and $G_{M_e}$, the equilibrium  
 dimensionless buoyancy and wind shear  
 parameters.   Both $G_H$ and $G_M$, and their equilibrium values $G_{H_e}$ and $G_{M_e}$,  
 are functions of the Richardson number.  
   
 \noindent  
 For the detailed equations and derivations of the modified level 2.5 closure scheme,  
 see Helfand and Labraga, 1988.  
   
 \noindent  
 In the surface layer, ${\bf {ET}}$ is the exchange coefficient for heat and moisture,  
 in units of $m/sec$, given by:  
 \[  
 {\bf ET_{Nrphys}} =  C_t * u_* = C_H W_s  
 \]  
 \noindent  
 where $C_t$ is the dimensionless exchange coefficient for heat and moisture from the  
 surface layer similarity functions (see diagnostic number 9), $u_*$ is the surface  
 friction velocity (see diagnostic number 67), $C_H$ is the heat transfer coefficient,  
 and $W_s$ is the magnitude of the surface layer wind.  
 \\  
   
 \noindent  
 {\bf 12)  \underline {EU}  Diffusivity Coefficient for Momentum ($m^2/sec$) }  
   
 \noindent    
 In the level 2.5 version of the Mellor-Yamada (1974) hierarchy, the turbulent heat  
 momentum flux for the atmosphere above the surface layer can be expressed as a turbulent  
 diffusion coefficient $K_m$ times the negative of the gradient of the u-wind.  
 In the Helfand and Labraga (1988) adaptation of this closure, $K_m$  
 takes the form:  
 \[  
 {\bf EU} = K_m = -{( {\overline{u^{\prime}w^{\prime}}}) \over {\pp{U}{z}} }  
  = \left\{ \begin{array}{l@{\quad\mbox{for}\quad}l} q \, \ell \, S_M(G_M,G_H) & \mbox{decaying turbulence}  
 \\ { q^2 \over {q_e} } \, \ell \, S_{M}(G_{M_e},G_{H_e}) & \mbox{growing turbulence} \end{array} \right.  
 \]  
 \noindent  
 where $q$ is the turbulent velocity, or $\sqrt{2*turbulent \hspace{.2cm} kinetic \hspace{.2cm}  
 energy}$, $q_e$ is the turbulence velocity derived from the more simple level 2.0 model,  
 which describes equilibrium turbulence, $\ell$ is the master length scale related to the layer  
 depth,  
 $S_M$ is a function of $G_H$ and $G_M$, the dimensionless buoyancy and  
 wind shear parameters, respectively, or a function of $G_{H_e}$ and $G_{M_e}$, the equilibrium  
 dimensionless buoyancy and wind shear  
 parameters.   Both $G_H$ and $G_M$, and their equilibrium values $G_{H_e}$ and $G_{M_e}$,  
 are functions of the Richardson number.  
   
 \noindent  
 For the detailed equations and derivations of the modified level 2.5 closure scheme,  
 see Helfand and Labraga, 1988.  
   
 \noindent  
 In the surface layer, ${\bf {EU}}$ is the exchange coefficient for momentum,  
 in units of $m/sec$, given by:  
 \[  
 {\bf EU_{Nrphys}} = C_u * u_* = C_D W_s

 \noindent  
 The net longwave heating rate is calculated as the vertical divergence of the  
 net terrestrial radiative fluxes.  
 Both the clear-sky and cloudy-sky longwave fluxes are computed within the  
 longwave routine.  
 The subroutine calculates the clear-sky flux, $F^{clearsky}_{LW}$, first.  
 For a given cloud fraction,  
 the clear line-of-sight probability $C(p,p^{\prime})$ is computed from the current level pressure $p$  
 to the model top pressure, $p^{\prime} = p_{top}$, and the model surface pressure, $p^{\prime} = p_{surf}$,  
 for the upward and downward radiative fluxes.  
 (see Section \ref{sec:fizhi:radcloud}).  
 The cloudy-sky flux is then obtained as:  
     
 \noindent  
 \[  
 F_{LW} = C(p,p') \cdot F^{clearsky}_{LW},  
 \]  
   
 \noindent  
 Finally, the net longwave heating rate is calculated as the vertical divergence of the

 \[  
 \pp{\rho c_p T}{t} = - {\partial \over \partial z} F_{LW}^{NET} ,

 The net Shortwave heating rate is calculated as the vertical divergence of the

 The clear-sky and cloudy-sky shortwave fluxes are calculated separately.  
 For the clear-sky case, the shortwave fluxes and heating rates are computed with  
 both CLMO (maximum overlap cloud fraction) and  
 CLRO (random overlap cloud fraction) set to zero (see Section \ref{sec:fizhi:radcloud}).  
 The shortwave routine is then called a second time, for the cloudy-sky case, with the  
 true time-averaged cloud fractions CLMO  
 and CLRO being used.  In all cases, a normalized incident shortwave flux is used as  
 input at the top of the atmosphere.  
   
 \noindent  
 The heating rate due to Shortwave Radiation under cloudy skies is defined as:  
 \[  
 \pp{\rho c_p T}{t} = - {\partial \over \partial z} F(cloudy)_{SW}^{NET} \cdot {\rm RADSWT},

 $c_p$ is the heat capacity of air at constant pressure, RADSWT is the true incident  
 shortwave radiation at the top of the atmosphere (See Diagnostic \#48), and

 {\bf CLROSW} is the time-averaged random overlap cloud fraction that has been filled by the Relaxed  
 Arakawa/Schubert and Large-scale Convection schemes and will be used in the Shortwave  
 Radiation algorithm.  These are  
 convective and large-scale clouds whose radiative characteristics are not  
 assumed to be correlated in the vertical.  
 For a complete description of cloud/radiative interactions, see Section \ref{sec:fizhi:radcloud}.

 It should be noted that {\bf RADSWT}, as well as

 are calculated at the top of the atmosphere (p=0 mb).  However, the

 {\bf 54)  \underline {USTAR}  Surface-Stress Velocity ($m/sec$) }

 Over the land surface, the surface roughness length is interpolated to the local

 value.  
   
 \[

 {\bf 58)  \underline {SWCLR} Clear sky Heating Rate due to Shortwave Radiation ($deg/day$) }  
   
 \noindent  
 The net Shortwave heating rate is calculated as the vertical divergence of the  
 net solar radiative fluxes.  
 The clear-sky and cloudy-sky shortwave fluxes are calculated separately.  
 For the clear-sky case, the shortwave fluxes and heating rates are computed with  
 both CLMO (maximum overlap cloud fraction) and  
 CLRO (random overlap cloud fraction) set to zero (see Section \ref{sec:fizhi:radcloud}).  
 The shortwave routine is then called a second time, for the cloudy-sky case, with the  
 true time-averaged cloud fractions CLMO  
 and CLRO being used.  In all cases, a normalized incident shortwave flux is used as  
 input at the top of the atmosphere.  
   
 \noindent  
 The heating rate due to Shortwave Radiation under clear skies is defined as:  
 \[  
 \pp{\rho c_p T}{t} = - {\partial \over \partial z} F(clear)_{SW}^{NET} \cdot {\rm RADSWT},  
 \]  
 or  
 \[  
 {\bf SWCLR} = \frac{g}{c_p } {\partial \over \partial p} F(clear)_{SW}^{NET}\cdot {\rm RADSWT} .  
 \]  
   
 \noindent  
 where $g$ is the accelation due to gravity,  
 $c_p$ is the heat capacity of air at constant pressure, RADSWT is the true incident  
 shortwave radiation at the top of the atmosphere (See Diagnostic \#48), and

 {\bf 69)  \underline {SDIAG1} User-Defined Surface Diagnostic-1 }  
   
 \noindent  
 The GCM provides Users with a built-in mechanism for archiving user-defined  
 diagnostics.  The generic diagnostic array QDIAG located in COMMON /DIAG/, and the associated  
 diagnostic counters and pointers located in COMMON /DIAGP/,  
 must be accessable in order to use the user-defined diagnostics (see Section \ref{sec:diagnostics:diagover}).    
 A convenient method for incorporating all necessary COMMON files is to  
 include the GCM {\em vstate.com} file in the routine which employs the  
 user-defined diagnostics.  
   
 \noindent  
 In addition to enabling the user-defined diagnostic (ie., CALL SETDIAG(84)), the User must fill  
 the QDIAG array with the desired quantity within the User's  
 application program or within modified GCM subroutines, as well as increment  
 the diagnostic counter at the time when the diagnostic is updated.    
 The QDIAG location index for {\bf SDIAG1} and its corresponding counter is  
 automatically defined as {\bf ISDIAG1} and {\bf NSDIAG1}, respectively, after the  
 diagnostic has been enabled.    
 The syntax for its use is given by

 {\bf 81 \underline {CLDFRC} Total 2-Dimensional Cloud Fracton ($0-1$) }  
   
 If we define the  
 time-averaged random and maximum overlapped cloudiness as CLRO and  
 CLMO respectively, then the probability of clear sky associated  
 with random overlapped clouds at any level is (1-CLRO) while the probability of  
 clear sky associated with maximum overlapped clouds at any level is (1-CLMO).  
 The total clear sky probability is given by (1-CLRO)*(1-CLMO), thus  
 the total cloud fraction at each  level may be obtained by  
 1-(1-CLRO)*(1-CLMO).  
   
 At any given level, we may define the clear line-of-site probability by  
 appropriately accounting for the maximum and random overlap  
 cloudiness.  The clear line-of-site probability is defined to be  
 equal to the product of the clear line-of-site probabilities  
 associated with random and maximum overlap cloudiness.  The clear  
 line-of-site probability $C(p,p^{\prime})$ associated with maximum overlap clouds,  
 from the current pressure $p$  
 to the model top pressure, $p^{\prime} = p_{top}$, or the model surface pressure, $p^{\prime} = p_{surf}$,  
 is simply 1.0 minus the largest maximum overlap cloud value along  the  
 line-of-site, ie.  
   
 $$1-MAX_p^{p^{\prime}} \left( CLMO_p \right)$$  
   
 Thus, even in the time-averaged sense it is assumed that the  
 maximum overlap clouds are correlated in the vertical.  The clear  
 line-of-site probability associated with random overlap clouds is  
 defined to be the product of the clear sky probabilities at each  
 level along the line-of-site, ie.  
   
 $$\prod_{p}^{p^{\prime}} \left( 1-CLRO_p \right)$$  
   
 The total cloud fraction at a given level associated with a line-  
 of-site calculation is given by
