AeroStat: Online Platform for the Statistical Intercomparison of Aerosols

PI: Gregory Leptoukh, NASA/GSFC

  • Provide online environment for convenient access to:

    • Satellite and ground-based aerosol data

    • Quality information and provenance

    • Calibration/validation data

  • Provide multi-sensor services:

    • Multi-sensor and model intercomparison

    • Cross-sensor bias adjustment

    • Data merging

  • Create collaborative environment for aerosol researchers to share ideas, workflows and results

Differences between various methods of aggregating aerosol data

Global MODIS Terra Aerosol Optical Depth for 2003 (over land and ocean) computed using different weighting methods

  • Use ontology to capture differences in data measurements and processing (leverage ESTO MDSA)

  • Use Level 2 Aerosol data to generate customized Level 3

  • Filter by Quality and Ancillary parameters (leverage ACCESS DQSS)

  • Use validation data (leverage ACCESS MAPSS)

  • Use linear and non-linear regression for cross-sensor bias

  • Adjust for Cross-sensor Bias

  • Integrate Aerosol Data Provenance (MDSA and Kepler)

  • Integrate the workflow system with the Collaborative environment

  • Use Cases Development 03/10

  • Alpha Release (internal) 07/10

  • Beta Release: Aeronet-ref. validation visualization w/collaboration 10/10

  • Add bias adjustment 01/11

  • Cross-sensor w/bias adjustment & merging 03/11

  • Cross-sensor w/non-linear bias adjustment & merging 08/11

  • Community feedback release 09/11

  • Refactored release for Long termMaintenance and Operations 12/11
