FLASHFlux - Fast Longwave And SHortwave Radiative Fluxes

Return to Data Products

The FLASHFlux link to external site project was initiated at the NASA Langley Research Center to meet the needs of the science community for global near real-time surface and TOA radiative fluxes. This was accomplished by speeding up the processing of CERES and MODIS TOA observations with fast radiation algorithms to produce the fluxes within about a week of satellite measurements.

FLASHFlux Level3 (FLASH_TISA) Documentation

  • Data Quality Summary link to external site — Highlights the accuracy of this product as determined by the FLASHFlux Science Team.

FLASHFlux Level3 (FLASH_TISA) Product Features

  • Provides a near real-time daily averaged product within about a week of observation.
    • Useful for Quicklook for daily averaged TOA and surface radiation data products.
  • Does not use the official CERES instrument calibration and thus contains higher uncertainties in data products
    (see Data Quality Summary link to external site).
    • It is strongly advised to NOT append the FLASHFlux Level3 TOA products with other CERES climate products to detect climate signals without careful scrutiny of overlap periods.
    • Do not append FLASHFlux Level3 surface products with other CERES climate products due to significant algorithm differences.
