This notebook compares the TEMPO ultra-violet aerosol index (UVAI) against the DSCOVR EPIC UVAI.
The collections used in the Notebook are TEMPO_O3TOT_L2_V03 and DSCOVR_EPIC_L2_AER_03.
The user selects the Temporal Extent of interest, and the code searches for DSCOVR EPIC granules within the TEMPO field of regard (FOR) and within the user's timeframe using the earthaccess library. If TEMPO granules exist with the stipulated parameters, DSCOVR EPIC UVAI retrievals are interpolated to the positions of the TEMPO pixels, then the interpolated values are written into a netCDF file along with TEMPO geolocations.
The original UVAI from DSCOVR EPIC and TEMPO are plotted along with interpolated DSCOVR EPIC values in the same plot. Output images are written into PNG files.
Example of plotted values:
