OMPS-NPP L3 Nadir Mapper Ozone Total Column Daily Grid

OMPS-NPP L3 Nadir Mapper Ozone Total Column Daily Grid is an open NASA Earthdata product for daily global total ozone mapping from OMPS cross-track measurements on Suomi-NPP ^[1]. The product combines orbital OMPS observations into a fixed Level-3 grid, giving users a map-ready dataset for ozone-layer monitoring and daily spatial analysis ^[1]. Its total ozone fields are provided on a 1 degree by 1 degree grid, which fits workflows that need consistent global coverage rather than individual orbital swaths ^[1]. NASA distributes the product through GES DISC under open Earthdata access, supporting repeat processing and integration into atmospheric-composition monitoring pipelines ^[1].
