Hello,
I was wondering if anyone else in the community has experienced issues with the Fast All-Sky Radiation Model (FARMS), specifically, the influence that its timestep seems to exert on plots of the time series for surface variables.
The time series that are written on the *.TS file, show a random stepping behavior at certain positions (circled in the example image included below for the V-wind component). I have noticed that the frequency of those step matches radt (the minutes between two successive radiation physics calls). Decreasing radt does not eliminate the appearance of those steps completely however.
For reference, I am including below a list of the physics models I am currently using :
Best,
Kieran
