OMI/Aura Hyperspectral UV Irradiance and Underwater Attenuation Coefficient 1-Orbit L2 Swath 13x24km V004 (OMOCNUV) at GES DISC

The Collection 4 Aura Ozone Monitoring Instrument (OMI) Hyperspectral Surface and Underwater UV Irradiances (OMOCNUV) product is now available from the NASA Goddard Earth Sciences Data and Information Services Center. The OMOCNUV product contains surface UV irradiances from 290 to 399 nm, as well as planar and scalar irradiances and diffuse attenuation coefficients over water, and other ancillary variables. Details can be found in the OMOCNUV readme document (see Documentation tab).

The OMOCNUV files are stored in the version 4 netCDF format. Each Level-2 file contains data from the sunlit portion of an orbit (~53 minutes). There are approximately 14 orbits per day. The average file size is about 91 MB.
