OMI/Aura Water Vapor (H2O) Total Column 1-orbit L2 Swath 13x24 km V004 (OMH2O)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/measures/ch2o_chocho_h2o/data2023
The Aura Ozone Monitoring Instrument (OMI) Water Vapor Product OMH2O contains total vertical column H2O, standard errors (rms and sigma), quality flags, geolocation and other ancillary information.
Description
The algorithm leads for this product are Helen Wang and Gonzalo Gonzalez Abad the Harvard-Smithsonian Center, Cambridge, MA. The OMH2O files are stored in the version 4 netCDF format.
Each file contains data from the day lit portion of an orbit (~53 minutes). There are approximately 14 orbits per day. The average file size for the OMH2O data product is about 35 MB.
