Description

The Aura Ozone Monitoring Instrument (OMI) Formaldehyde Product OMHCHO contains total vertical column HCHO, standard errors (rms and sigma), quality flags, geolocation and other ancillary information. The algorithm lead for this product is Gonzalo Gonzalez Abad from the Harvard-Smithsonian Center, Cambridge, MA.

The OMHCHO 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 OMHCHO data product is about 35 MB.
