Tips
Testing
Create an artificial surface containing a Gaussian mound:
r.surf.volcano out=gauss method=gaussian kurtosis=1
Time step
The following three images demonstrate the effects of using different step parameters.
r.sun -s elevin="gauss" glob_rad="rad.global.30minT" day=180
r.sun -s elevin="gauss" glob_rad="rad.global.15minT" day=180
r.sun -s elevin="gauss" glob_rad="rad.global.03minT" day=180
Default 30 minute time step.
15 minute time step.
3 minute time step.
The 3 minute time step takes roughly ten times as long to run as the 30 minute timestep.
