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.

Archive – Next Generation (ANGe)• Modernized ingest, archive, and distribution tools
- Advanced hardware and software systems
- Secure, redundant systems for data integrity
- Cost-effective, scalable data management solution
• Replacing two existing ASDC systems:- EOS Core System (ECS)- Langley TRMM and Terra Information System (LATIS)
• Distributed, multi-tier architecture- Grid computing environment enables simultaneous data access- Web service archive access allows more refined data search- Open source metadata database for external system integration
