Hi,
Taking a wild guess.......the most obvious reason is the wrong missing value flag for the
original dataset. Along with other information, please send in the output of following commad
too.....

yes? set data ...
yes? list `variable_name,r=bad`

Also just make a shade plot of the original data (without any /levels qualifier) and make sure there
is no data values displayed over land and the default colorbar shows reasonable values.

Thanks and Regards,

Jaison

Hi Simi,
We have not had other reports of this. Can you give us more information? If you show the shape of your variable, and the commands you are using, then we might be able to tell what's happening. So, with the names of your dataset and variable, of course, what are the output of:

yes? set data xx.nc
yes? show data
yes? show grid var

and then show the commands you are using to define the climatology.

hi,
When I am using @mod function in ferret to find the climatology,
eventhough the original data doen't have any values on the land region; the
final data after regridding using @mod has values on the land region. How can
i get rid of this. Any suggestions will be very helpful.

Thanks
simi
