\subsubsection{Introduction |
10 |
\label{sec:pkg:exf:intro}} |
11 |
|
12 |
The external forcing package, in conjunction with the |
13 |
calendar package (cal), enables the handling of real-time |
14 |
(or ``model-time'') forcing |
15 |
fields of differing temporal forcing patterns. |
16 |
It comprises climatological restoring and relaxation. |
17 |
Bulk formulae are implemented to convert atmospheric fields |
18 |
to surface fluxes. |
19 |
An interpolation routine provides on-the-fly interpolation of |
20 |
forcing fields an arbitrary grid onto the model grid. |
21 |
|
22 |
CPP options enable or disable different aspects of the package |
23 |
(Section \ref{sec:pkg:exf:config}). |
24 |
Runtime options, flags, filenames and field-related dates/times are |
25 |
set in \texttt{data.exf} and \texttt{data.exf\_clim} |
26 |
(Section \ref{sec:pkg:exf:runtime}). |
27 |
A description of key subroutines is given in Section |
28 |
\ref{sec:pkg:exf:subroutines}. |
29 |
Input fields, units and sign conventions are summarized in |
30 |
Section \ref{sec:pkg:exf:fields_units}, and available diagnostics |
31 |
output is listed in Section \ref{sec:pkg:exf:fields_diagnostics}. |

\subsubsection{EXF configuration, compiling \& running} |

\paragraph{Compile-time options |
38 |
\label{sec:pkg:exf:config}} |
39 |
~ |
40 |
|
41 |
As with all MITgcm packages, EXF can be turned on or off at compile time |
42 |
% |
43 |
\begin{itemize} |
44 |
% |
45 |
\item |
46 |
using the \texttt{packages.conf} file by adding \texttt{exf} to it, |
47 |
% |
48 |
\item |
49 |
or using \texttt{genmake2} adding |
50 |
\texttt{-enable=exf} or \texttt{-disable=exf} switches |
51 |
% |
52 |
\item |
53 |
\textit{required packages and CPP options}: \\ |
54 |
EXF requires the calendar package \texttt{cal} to be enabled; |
55 |
no additional CPP options are required. |
56 |
% |
57 |
\end{itemize} |
58 |
(see Section \ref{sect:buildingCode}). |
59 |
|
60 |
Parts of the EXF code can be enabled or disabled at compile time |
61 |
via CPP preprocessor flags. These options are set in either |
62 |
\texttt{EXF\_OPTIONS.h} or in \texttt{ECCO\_CPPOPTIONS.h}. |
63 |
Table \ref{tab:pkg:exf:cpp} summarizes these options. |

\subsubsection{Run-time parameters |
108 |
\label{sec:pkg:exf:runtime}} |
109 |
|
110 |
Run-time parameters are set in files |
111 |
\texttt{data.pkg}, \texttt{data.exf}, and |
112 |
\texttt{data.exf\_clim} (for relaxation/climatological fields) |
113 |
which are read in \texttt{exf\_readparms.F}. |
114 |
Run-time parameters may be broken into 3 categories: |
115 |
(i) switching on/off the package at runtime, |
116 |
(ii) general flags and parameters, and |
117 |
(iii) attributes for each forcing and climatological field. |
118 |
|
119 |
\paragraph{Enabling the package} |
120 |
~ \\ |
121 |
% |
122 |
A package is usually switched on/off at runtime by setting |
123 |
(e.g. for EXF) \texttt{useEXF = .TRUE.} in \texttt{data.pkg}. |
124 |
For EXF this flag is omitted, i.e. EXF is always ON if it is compiled. |

All EXF fields are listed in Section \ref{sec:pkg:exf:fields_units}. |

Each field has a number of attributes which can be customized. |
168 |
They are summarized in |
169 |
Table \ref{tab:pkg:exf:runtime_attributes}. |
170 |
To obtain an attribute for a specific field, e.g. \texttt{uwind} |
171 |
prepend the field name to the listed attribute, e.g. for attribute |
172 |
\texttt{period} this yields \texttt{uwindperiod}: |

The following block is taken from the \texttt{data.exf} file |

of the veification experiment \texttt{global\_with\_exf/}. |
234 |
It defines attributes for the heat flux variable \texttt{hflux}: |
235 |
|
236 |
\begin{verbatim} |
237 |
hfluxfile = 'ncep_qnet.bin', |
238 |

EXF will read a file of name 'ncep\_qnet.bin'. |

Its first record represents January 1st, 1991 at 00:00 UTC. |
251 |
Next record is 2592000 seconds (or 30 days) later. |
252 |
Interpolation on-the-fly is used (in the present case trivially |
253 |
on the same grid, but included nevertheless for illustration), |
