Re: math with Netcdf and ASCII data
Hi Wendy Wang,
If you can play around the time axis...it is very easy.
Earlier Barry Baker asked a similar question and he posted a nice summary
about how he finally did it. Please have a look at that mail in the
archive :
http://ferret.pmel.noaa.gov/Ferret/Mail_Archives/fu_2003/msg01060.html
(Or if want to trace the whole chain..then look at
http://ferret.pmel.noaa.gov/Ferret/Mail_Archives/fu_2003/msg01049.html)
If you find any difficulty in going ahead with this ...please let us
know.
With Regards
Jaison
