[ncl-talk] convert png to nc file after plot command

[zoe jacobs]

Many thanks of both you .
Dear Tabith the method you suggested actually work, but it does not give me
what I need. I want to have exactly the plotted result but in nc format.
Once I did your suggestion, I got a nc file, with no exact values of
precipitation for each grid cell, and x and y axises converted to
something else. Would any one have other suggestions please?
Best wishes,
