C !DESCRIPTION: |

|
|
C computes CDOM from Chlorophyll |
| 18 |
|
|
C |

|
|
c ANNA I have changed this a bit from WG code |
| 20 |
|
|
c ------------- this is WG code: |
| 21 |
|
|
c do k = 1,km |
| 22 |
|
|
c actot450 = 0.0 |
| 23 |
|
|
c atot450 = 0.0 |
| 24 |
|
|
c do n = 1,nchl |
| 25 |
|
|
c actot450 = actot450 + P(k,n)*ac(n,nl450) |
| 26 |
|
|
c enddo |
| 27 |
|
|
c atot450 = aw(nl450) + actot450 |
| 28 |
|
|
c do nl = 1,nlt |
| 29 |
|
|
c acdom(k,nl) = 0.2*atot450*excdom(nl) |
| 30 |
|
|
c enddo |
| 31 |
|
|
c enddo |
| 32 |
|
|
c do nl = 1,nlt |
| 33 |
|
|
c write(6,*)'nl,lam,aw,ac,acdom = ',nl,lam(nl), |
| 34 |
|
|
c *aw(nl),ac(1,nl),acdom(1,nl) |
| 35 |
|
|
c enddo |
| 36 |
|
|
c this implies P biomass is being scaled by the absorption of phytoplankton |
| 37 |
|
|
c at 450nm. ie. the waveband on the main chl-a peak. |
| 38 |
|
|
c so (i think) this is effectively getting the absorption by the phytoplankton |
| 39 |
|
|
c In our version, since we have phyto chl we need to scale the |
| 40 |
|
|
c chlorophyll normalised absorption spectra (the inputs) |
| 41 |
|
|
c by phyt chl rather than phyto biomass |
| 42 |
|
