The OMPS-NPP L3 NM Ozone (O3) Total Column 1.0 deg grid daily product provides total ozone measurements from the Ozone Mapping and Profiling Suite (OMPS) Nadir-Mapper (NM) instrument on the Suomi-NPP satellite. The level-3 gridding algorithm is used to combine the orbital OMPS cross track measurements into a daily map product with a fixed global grid. Grid cells are computed as weighted averages of a given parameter derived for the field-of-views that overlay the given cell. The current version of this product includes UV aerosol index and reflectivity at 331 nm retrievals as well. Each granule contains data for a full day. Spatial coverage is global (-90 to 90 degrees latitude), with a resolution of 1.0 degree in longitude and 1.0 degree in latitude, and array size of 360 by 180. The files are written using the Hierarchical Data Format Version 5 or HDF5.
