Re: Integrate a grid?

Hi Joe,

Perhaps it is anathema to suggest using some other software, but I'm a big believer in using the best tool for the job.  Ferret (http://ferret.pmel.noaa.gov/Ferret/) is a great way to get simple integrals like this:

use heatflux.nc
list foo[x=@din,y=@din]

will do the trick.  Ferret has less sophisticated graphics, but excels at simple netCDF I/O and analysis.

Regards,

Andy
