Data sets

AERONET Aerosol Optical Depth (V3) - Solar data base AERONET https://aeronet.gsfc.nasa.gov/new_web/download_all_v3_aod.html

AERONET Aerosol Inversion (V3) data base AERONET https://aeronet.gsfc.nasa.gov/new_web/download_all_v3_inversions.html

Short summary

With the AERONET database, this study derives dust-related conversion factors at oceanic sites used in the POLIPHON method, which can convert lidar-retrieved dust extinction to ice-nucleating particle (INP)- and cloud condensation nuclei (CCN)-relevant parameters. The particle linear depolarization ratio in the AERONET aerosol inversion product is used to identify dust data points. The derived conversion factors can be applied to inverse 3-D global distributions of dust-related INPCs and CCNCs.
