[ncl-talk] Regridding OMI NO2 to WRF domain

[markus.mingel at libero.it]

Hi All,

I am trying to regrid OMI NO2 data to WRF grid using ESMF, but without success; in particular, the result of ESMF_regrid has 3 dimensions while I expect data on a LON-LAT grid:


Dimensions and sizes: [scanline | 1644] x [290] x [380]
Coordinates:
scanline: [0..1643]
Number Of Attributes: 9
missing_value : -1e+20
remap : remapped via ESMF_regrid_with_weights: Nearest source to destination
lon2d : <ARRAY of 538200 elements>
lat2d : <ARRAY of 538200 elements>
_FillValue : -1e+20
time : 631152006
units : molecules cm-2
long_name : tropospheric vertical column of nitrogen dioxide


Does anyone know how to regrid these data? I attached my script, while a sample input file (QA4ECV_L2_NO2_OMI_20150101T062700_o55658_fitB_v1.nc) can be found on ftp.

Thanks into advance for help,

Markus
