NASA Satellite Product Levels
Teaser image
Main content
NASA data products are categorized into different "Levels". These are product dependent but the following description for OMI (Ozone Monitoring Instrument) data products is a general guideline:
Level-1B (L1B): Products containing geolocated and calibrated spectral radiance and solar irradiance data.
Level-2 (L2): Atmospheric products derived from the L1B product. One file per orbit.
L2G: Daily binned global products derived from the L2 products.
Level-3 (L3): Averaged global gridded products, screened for bad data points.
Post-Processing involves changes only in ancillary data or information.
Re-Processing indicates data processing due to changes in the Retrieval Algorithms.
