Subject: Re: [ferret_users] Reading
variables from an ascii file
Hi Arturo,
If your data has NaN at land locations then for
ASCII data you should just edit that or use your C program to change those
values to some known value out of the valid range of the data, and then after
reading the data do,
SET VAR/BAD=99999 sst
or
whatever the variable name is. (Use the same kind of syntax to set units
for variables: SET VAR/UNITS="deg C" sst)
0.2 minute resolution is very
high resolution! There is the etopo02 dataset which is 2 minutes'
resolution.

Hi Ansley,
Thanks a lot, it works fine! Now, some
data are over land and they are NaN values indeed. According
to "Setting a missing value" at Ferret FAQ having an ocean mask with
earth's surface may help to get only data over ocean, Where could I find
an ocean mask with earth's surface at 0.2
minute resolution?
Cheers
