Thanks a lot! Yes, ESMF_regrid is much quicker.
It mostly worked for me except negative values generated,
see my original data shown at http://www.caps.ou.edu/micronet/CO2_and_otherGHG/WRFV3.8.1/YSU/wrfchem3.8.1_NARR_CONUS_nudge2_tracer16_Comet.2011080600/wrfout_d01_E_CO2_EDGAR_2.png
and the interpolated data shown
at http://www.caps.ou.edu/micronet/CO2_and_otherGHG/WRFV3.8.1/YSU/wrfchem3.8.1_NARR_CONUS_nudge2_tracer16_Comet.2011080600/wrfout_d01_E_CO2_0.png
You may notice in the right-lower corner the contour information shows Min=-20.745
Any suggestion to improve this?
My interpolation script at http://www.caps.ou.edu/micronet/CO2_and_otherGHG/WRFV3.8.1/YSU/wrfchem3.8.1_NARR_CONUS_nudge2_tracer16_Comet.2011080600/Interp_edgar42_to_wrfchemi_NEI.ncl
Thanks a lot!

rgrid2rcm can be slow.
Use ESMF: there are exam
http://www.ncl.ucar.edu/Applications/ESMF.shtml
There are numerous examples of going from rectilinear ('rgrid') to curvilinear ('rcm')
Examples 9, 15, 28-30, 32, 33,

I am doing
"
dummy1 = rgrid2rcm (elat, elon, emi_co2, lat2d, lon2d, 0)
"
where lat2d and lon2d have a dimension of 442x265
The script appears to take forever.
Any other ways to do a faster interpolation?
Thanks a lot!
