difference between two files

[Gisele Zepka]

Hello users!!

I have two files with different resolutions and I want to compare the 
differences between them. I used the regrid function to take both in the 
same resolution. The regrided file is just one hour, while in the other 
I have a range of 22 times. I want to compare just the hour of the 
first, so I have two problems when I try to do that: an error of 
resolution, because the two files don't have the same quantity of points 
in x and y and I don't know how to set the time just for the second and 
then calculate the difference.

Please any help will be nice!

Thanks,
Gisele
