Re: writing lat in the file

Without running your code, it looks to me like the loop that defines the "lat" variable never gets executed. Your do loop begins:

do j = 0, dimsizes(files)-143

Are you sure that 'dimsizes(files)-143' produces a non-negative integer?

Also if there are indeed more than a single file (that use the same coordinate grid) then it is not very efficient to read the lat and lon variables each time through the loop. You could read these from a single file prior to starting the loop.
