[cam-users] What is pcols?

[Chul Eddy Chung]

I am running CAM2 at T42/L26.  I am trying to modify the solar radiation 
code in order to put spatially-heterogenious absorbing aerosol effects. 
I have a hard time understanding how the CAM2.0 treats the latitude and 
longitude indices.  In CCM3, the solar radiation code calculated all the 
levels and longitudes at a given latitude.  Seems like the CAM2 solar 
radiation code only calculates all the levels at a given latitude and 
given longitude.

I have specific questions.  What is pcols (PCOLS)?  The value is 16 in 
case of T42/L26 CAM2, and according to 'ppgrid.F90', pcols is number of 
columns (max).  What is the column as opposed to layer?
