Level 0 data are packaged into two-hour "chunks" of observations in the life of the spacecraft (and the OMI aboard it) irrespective of orbital boundaries. They contain orbital swath data. • Level 1B processing takes Level 0 data and calibrates, geo-locates and packages the data into orbits. They contain orbital swath data. • Level 2 products contain orbital swath data. • Level 3 products contain global data that are composited over time (daily or monthly) or over space for small equal angle (latitude longitude) grids covering the whole globe. 2019-05-22T00:00:00.00Z series NASA_OMI eng -90.0 -180.0 90.0 -180.0 90.0 180.0 -90.0 180.0 -90.0 -180.0 External Data
