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

[Tabish Ansari]

Hi Zoe,

If you just want to store the resultant variable (monthly averages of
precipitation) to a new netcdf file, you can achieve that just by adding 2
lines of code before or after the plotting routine:

b = addfile("myNCfile.nc", "c") ; open in create mode
b->prcClm = prcClm

Cheers,

Tabish
