[ncl-talk] Question about regrid 1) different commands get different results; 2)input emission amount or emission intensity

[王梓元]

Hi All
Now I have an emission amount inventory (lat 33:73, lon -12:45), with resolution 0.1*0.1, the emission variable E_HFC_1234 is the emission amount of each grid with unit Mg, as 'HFC.nc' show. I want to interpolate to lower resolution 1*1.
1. I tried 3 different commands: "linint2", "area_conserve_remap_Wrap", and "area_hi2lores_Wrap" But three return results are different (try in regrid.ncl)
2) The input "fi" of each command should be the emission amout? or the emission intensity of each grid? Do I need to calculate E_HFC_1234 into emission intensity, by dividing the area of each grid? If so, which command can I use to calculate area?
Thanks

Best
Ziyuan
