GEWEX Radiative Flux Assessment

 Earth with Sun's radiation.

The ultimate goal of the Global Energy and Water Cycle Experiment (GEWEX) global data analysis projects is to obtain observations of the elements of the global energy and water cycle with sufficient detail and accuracy to diagnose the causes of recent climate variations in terms of the energy and water exchanges among the main climate components (atmosphere, ocean, land, cryosphere, biosphere). The GEWEX Radiative Flux Assessment (RFA) project will provide a forum for consistent analysis of long-term radiative flux products, primarily top-of-atmosphere (TOA) and surface fluxes, to establish a foundation for better global radiation budget analysis.

Data access is restricted to assessment participants until the data are made publicly available (currently anticipated to be May 2009). To access the interim data you need an ASDC user account and approval from the LaRC GEWEX-RFA organizing committee. Join the assessment team.

The GEWEX-RFA data products should not be used in publications while the assessment is underway. After the assessment has been completed, when data from the GEWEX Radiative Flux Assessment are used in a publication, we request the following acknowledgment be included: "The GEWEX Radiative Flux Assessment data were obtained from the NASA Langley Research Center Atmospheric Science Data Center." In addition, the provider of each data set used should be specifically acknowledged. See the product description file(s) for details.
