[ncl-talk] Problem writing poisson_grid_fill results to a file

[Dennis Shea]

The fundamental rule of data processing is *look at your data*

Did you look at your data??? I don't think so.

Also, you showed no attempt to write data out.

[1]
The file has 'nan' .... NCL does not understand 'nan'.
You must change to _FillValue
See: http://www.ncl.ucar.edu/Document/Functions/Built-in/isnan_ieee.shtml

[2]
After [1], use 'stat_dispersion' to examine the distribution of data.
This is for *your* benefit ... not NCL's benefit

[3]
To write out a file see:

[4]
I think your source data is messed up.



ncl 0> f =
addfile("corrected_extreme5Dayspr_bcc-csm1-1_rcp45_r1i1p1_2006-2035.nc","r")

ncl 1> p = f->pr
ncl 2> print(p)
