Data Center Primary Functions
• Receive data from numerous data providers
• Raw data from satellite missions
• Archival products for distribution
• Process data to create highest quality science data
products from lower level satellite data
• Archive data with high standards of integrity to ensure
the long term preservation and use of the science data
• Distribute data to a wide variety of customers
• Provide expert assistance on data management and
use of data holdings

Data Processing
• Level 0 – Unprocessed instrument data with
communications artifacts removed.
• Level 1 - Reconstructed instrument data annotated with
ancillary information (calibration coefficients).
• Level 2 – Algorithms applied to derive geophysical
parameters.
• Level 3 – Parameter data mapped onto a standard
space-time grid.
• Level 4 – Model output or results from analysis of
multiple lower level data sets.
