Converting .dat to .nc
Added by Lucas Do about 5 years ago
Hello,
I'm trying to convert a .dat file that has lat/lon fields to .nc to be mapped. From previous threads here it seems that I do so in CDO using a gridfile, but I've been unable to set one up successfully.
Attached are the .dat file I want to convert, a .nc4 file that has the proper time/lat/lon, and the gridfile I've been trying to use.
Any help with this will be appreciated.

Hi Lucas,
sorry, but cdo is not able to handle this kind of data.
Your data (snippet):

You can use a shell script to extract the variable you need and sort it by time. Or you use NCL to read the data and bring the data in an acceptable format to write it to a netCDF file.

Karin,
Thanks for the reply, I'll look into doing that.
