Description
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.

Variables
The table below lists the variables contained within a single granule for this dataset. Variables often contain observed or derived geophysical measurements collected from a variety of sources, including remote sensing instruments on satellite and airborne platforms, field campaigns, in situ measurements, and model outputs. The terms variable, parameter, scientific data set, layer, and band have been used across NASA’s Earth science disciplines; however, variable is the designated nomenclature in NASA’s Common Metadata Repository (CMR). Variable metadata attributes such as Name, Description, Units, Data Type, Fill Value, Valid Range, and Scale Factor allow users to efficiently process and analyze the data. The full range of attributes may not be applicable to all variables. Additional information on variable attributes is typically available in the data, user guide, and/or other product documentation.
For questions on a specific variable, please use the Earthdata Forum.
