How To Access Data
External Data (Restrained)
- Go to the Aura OMI collection on NASA's website
- Follow the steps described on the website to access the data.
Description
The OMI observations provide the following capabilities and features:
- A mapping of ozone columns at 13 km x 24 km and profiles at 13 km x 48 km
- A measurement of key air quality components: NO2, SO2, BrO, HCHO, and aerosol
- The ability to distinguish between aerosol types, such as smoke, dust and sulfates
- The ability to measure aerosol absorption capacity in terms of aerosol absorption optical depth or single scattering albedo
- A measurement of cloud pressure and coverage
- A mapping of the global distribution and trends in UV-B radiation.
The OMI data are available in the following four levels: Level 0, Level 1B, Level 2, and Level 3.
- Level 0 products are raw sensor counts. 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.
