[gradsusr] Error: Axis sizes not the same

[Justin Hicks]

GrADS users,

I previously used GLDAS files and mask files to calculate monthly area
averages. However, I am trying to get MERRA2 data to work with the masks
now. I keep getting an error saying:

ga-> run EXAMPLE_MASK_SCRIPT
Error in gagchk: axis sizes are not the same
Operation error:  Incompatable grids
  Dimension = 0
  1st grid range = -179 181   2nd = 1 360
Operation Error:  Error from maskout function
Operation Error:  Error from aave function
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression =
aave(maskout(prectot.2,mask.1(time=00:30z01feb1980)),lon=-179.5,lon=179.5,lat=-89.5,lat=89.5)


I tried to fix x and y grid points using the following command, but it did
not work:

aave(maskout(prectot.2(x=1,y=1),mask.1(x=1,y=1
,time=00:30z01feb1980)),lon=-179.5,lon=179.5,lat=-89.5,lat=89.5)





The result of 'q dims' of the mask file is:

Default file number is: 1
X is fixed     Lon = 0  X = 180.5
Y is fixed     Lat = -90  Y = 0.5
Z is fixed     Lev = 0  Z = 1
T is fixed     Time = 00:30Z01DEC1991  T = 143
E is fixed     Ens = 1  E = 1

The result of 'q dims' of the MERRA2 file is:

Default file number is: 2
X is fixed     Lon = 0  X = 1
Y is fixed     Lat = -90  Y = 1
Z is fixed     Lev = 0  Z = 1
T is fixed     Time = 00:30Z01DEC1991  T = 143
E is fixed     Ens = 1  E = 1


How can I get the x and y grid points to match up? I'm not even sure if
this is the issue, as the GLDAS and mask files didn't have matching x and y
grid points, yet they still worked.
