Welcome to the CERES/ARM/GEWEX Experiment home page. CAGEX is designed to test, develop, and validate retrievals of the Surface and Atmospheric Radiation Budget (SARB; the vertical profile of radiative fluxes) through the remaining life cycle of CERES, and to make the resultant dataset available to the scientific community. CAGEX provides a dataset with (1) soundings, aerosols, and satellite-based cloud properties sufficient to calculate fluxes with a radiative transfer model, (2) longwave and shortwave flux profiles calculated by the Fu-Liou model, and (3) ARM measurements that can be used to validate some of the specified inputs and calculated fluxes. The overview of CAGEX describes this beast in greater detail.
The buttons on the left are links to each version of CAGEX. The CAGEX grid system, a registration page, and acknowledgements and references are also available from the left side of this page. For more specific information, please go to the specific version.
Please take a look through the acknowledgements. Although CAGEX is put together here at NASA Langley, the effort would be impossible without the assistance of a large number of people who supply us with data, guidance, and technical and intellectual expertise.
One of the new features of version 2.2 is the treatment of diffuse flux, which has been adjusted to account for radiative cooling which affects the reported fluxes.
Any reference to CAGEX data in a publication should include the version number (ie. V2.2.0).
Note: Although the version 3 button is present, there is no information on it at this time. It's in the works.
