[RegCNET] Grid problem!

[Ho Thi Minh Ha]

Dear Monica Santese,

You should try this:

'open CHE.YYYYMMDD0100'  (file1)
'set lon lonstart lonend'         (e.g., lonstart, lonend are values of start and end longitude,
respecitively)
'set lat latstart latend'
'define a1=ave(ave(aext8,z=1,z=18)*18,t=1,t=4)'
'close 1'

'open CHE.YYYYMMDD0100'  (file2)
'set lon lonstart lonend'         (the same region as above)
'set lat latstart latend'
'define a2=ave(ave(aext8,z=1,z=18)*18,t=1,t=4)'
'd a1-a2'

'close 1'

Hope it would work

Best wishes,
Ha
