[RegCNET] Grid problem!

[S. Faisal Saeed]

Hi Monica,

If both the runs have the same resolution then i think you just have to "set lat lat1 lat2" and "set lon lon1 lon2" in Grads, before defining "a1" and also "a2".

Dear users,

  I have two different files CHE that come from two different runs with different numbers of pixels:
  One for iy=200 and jx = 200    and one for iy=185 and jx = 200.

  Now, if I want to plot the aerosol optical depth map of the differences between the AOD from the first run and AOD from the second one using : 
  a1=ave(ave(aext8,z=1,z=18)*18,t=1,t=4) and
  a2=ave(ave(aext8,z=1,z=18)*18,t=1,t=4)
  dif=a1-a2

  I have the error message:


  Operation error:  Incompatable grids 
    Dimension ranges aren't equivalent
    Dimension = 0
    1st grid range = -15 756   2nd = 1 771 
    Error ocurred at column 6
  DEFINE error:  Invalid expression. 


  Is there a way to plot the AOD differences for a lat-lon area that are common to the two files CHE?

  Thank you fory your help!!
