[ncl-talk] ESMF regrid

[Dennis Shea]

I have looked at the swath data. I am not sure why you want a 'global
grid'. Each swat only covers a limited region.

Attached are two scripts that uses NCL's binning procedures.

[1] regrid.binning.ncl creates an image (CERES_regrid_binning.png) of a
single swath.
[2] regrid.binning_all.ncl creates two images using *all* the images for
the current day
     (a) binned
     (b) use poisson_grid_fill to fill the missing values.


The example grid is 0.5 ... not the 0.05 you mentioned.

Good luck
D
