Title: MOPITT CO monthly climatology 2002-2021 Description: Monthly CO daytime measurements from the satellite-based instrument MOPITT, averaged between 2002 and 2021. We use level 3, version 9 joint NIR/TIR retrievals (doi: 10.5067/TERRA/MOPITT/MOP03JM.009). These data have been compiled for the NCAR ADF model evaluation package (https://github.com/NCAR/ADF). Note: August and September averages are missing 2009 data due to instrument downtime. Metadata URL: https://gdex.ucar.edu/dataset/id/53701a2e-ab7c-484b-b01a-2eab7c084b35.html
