Description

The standard states of processed data defined by the Earth Observing System Data and Information Ssytem (EOSDIS) Data Panel, which are also consistent with the Committee on Data Management, Archiving, and Computing (CODMAC) definitions.

Identifier	PrefLabel	Definition	Date
0	Level 0	Reconstructed, unprocessed instrument/payload data at full resolution; any and all communications artifacts, e.g., synchronization frames, communications headers, duplicate data removed. In most cases these data are provided by Earth Observing System (EOS) Data and Operations Systems (EDOS) to a Distributed Active Archive Center (DAAC) as Production Data Sets for processing to the Science Data Processing Segments (SDPs) in the DAAC or by the Science Investigator-led Processing Systems (SIPSs) to produce the higher-level products.	2016-02-01
1A	Level 1A	Reconstructed, unprocessed instrument data at full resolution, time-referenced, and annotated with ancillary information, including radiometric and geometric calibration coefficients and georeferencing parameters, e.g., platform ephemeris, computed and appended but not applied to the Level 0 data.	2016-02-01
1B	Level 1B	Level 1A data that have been processed to sensor units (not all instruments have Level 1B data products).	2016-02-01
2	Level 2	Derived geophysical variables at the same resolution and location as the Level 1 source data.	2016-02-01
3	Level 3	Variables mapped on uniform space-time grids, usually with some completeness and consistency.	2016-02-01
4	Level 4	Model output or results from analyses of lower level data, e.g., variables derived from multiple measurements.	2016-02-01
