Description
Hello Patrick,
Do you know how fsmc_gb (beta or soil moisture availability factor = (theta - smwilt / smcrit - smwilt )) is calculated in JULES? Is it the average value of beta over the soil 4 layers or only down to the rooting depth based on the PFT type? How can I get more info about it?
Many thanks,
Azin

Hi Azin:
Did you get everything figured out?
If there is any extra information about this ticket about what you needed to do to figure things out, could you add it here?

Hi Azin:
It looks like fsmc_gb is computed in (for example, in JULES 5.2) in the following file:
/group_workspaces/jasmin2/jules/pmcguire/jules_build/jules-vn5.2/src/science/surface/smc_ext_jls_mod.F90
Since the fsmc_shape and fsmc_mod variables are set to 0 in the ~\roses\u-al752\app\jules\rose-app.conf file, the code in smc_ext_jls_mod "calculates the soil moisture availability factor for each layer and weights with the root fraction to calculate the total availability factor, fsmc".
If you want to see all the occurrences of fsmc in the JULES 5.2 source tree, you could use grep, like this:
Does this help?
