electron transport rate code location

[jialiu]

Hello everyone, I want to modify the parameters of PAR. Could anyone know the location of the code where this parameter is located?

Not sure exactly what parameter you are looking for, but jmaxb1, the coefficient determining the response of the electron transport rate to amount of absorbed light, can usually be found in the lnd_in namelist. E.g., for release-cesm2.1.3,

&luna
jmaxb1 = 0.093563

See the technical description for how this is used:

2.10. Photosynthetic Capacity — ctsm release-clm5.0 documentation

Jmaxb0, the baseline proportion of nitrogen allocated for electron transport, can be found in biogeophys/LunaMod.F90
