OMI/Aura Chlorine Dioxide (OClO) Total Column 1-orbit L2 Swath 13x24 km V004 (OMOCLO)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/aura/omi/data2419
The Aura Ozone Monitoring Instrument (OMI) collection 4 Chlorine Dioxide Product OMOCLO is now available from the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) for public access.
Description
The algorithm leads for this product are the US OMI scientists Dr. Kelly Chance and Dr.
Gonzalo Gonzalez-Abad from the Harvard-Smithsonian Center, Cambridge, MA. The OMOCLO product contains slant column OClO, standard errors (rms and sigma), quality flags, geolocation and other ancillary information. The OMOCLO files are stored in the version 4 netCDF format.
