Dear colleagues,
I need to run a simulation (F2000climo) with different albedo in a specific region.
As I understand from posts it this forum, to do this I need to change fsurdat file, in particular variable "SOIL_COLOR" for all months (including winter months).
First question - is it necessary to change also other variables in addition to "SOIL COLOUR" like LAI (variable "MONTHLY_LAI", to set LAI value for all types of plants to zero to exclude their influence) or something else to do?
Second question - I need to do experiments with a 10% reduction in albedo compared to the control experiment (F200climo). As I understand, for example, I have soil colour 10 associated with dry (vis 0.25 and nir 0.39) and saturated (vis 0.14 and nir 0.28). The new values will be
Dry VIS: 0.20
Dry NIR: 0.312
Saturated VIS: 0.112
Saturated NIR: 0.224
which roughly corresponds to soil colour 14 (2.3. Surface Albedos — ctsm release-clm5.0 documentation). Is this correct?
Thank you very much!
