These documents are taken direct from the NASA GEDEX CD. The BADC is not responsible for their contents.
This page contains an overview of the documentation contained in the two GEDEX CD-Roms. For each data set there is a detailed description file and one or more summary files.
The description files contain information subdivided under 14 standard subheadings on the type of data, spatial and temporal characteristics, instrument description, data processing sequence, quality assessment, contacts for data production, output products and availability, data access, archive information, references, related data sets, summary/sample, and a final item for notes. The detailed description files are accompanied by an introductory outline file - aareadme.1st
There is a summary file for each parameter in the dataset, which is a terse description of the type of data and the spatial and temporal resolution.
Links are provided to the detailed description files (suffix .det ) and to the summary files (suffix .sum) from the CD-Rom. The filenames are unchanged from those on the CD-Rom.
These files whilst not relating directly to specific datasets in the GEDEX collection, give descriptions of some of the level 1 products from which many of the data sets are derived. Pointers to the level 1 description files are repeated with the relevant instruments in the following section.

Radiation Budget Data from the ERB
The radiation budget of the Earth is described in terms of Earth and solar irradiance. For the Earth Radiation Budget (ERB) experiment on Nimbus-6 and 7, ten solar channels (labelled 1 through 10) measure incoming solar radiation. Four Earth- looking channels (11 through 14) with fixed wide angle fields of view (WFOV) measure radiation from the entire visible Earth disc. Eight Earth-looking scanning channels with narrow angle fields of view (NFOV) measure the angular dependence of Earth radiation. Four of these channels (15 through 18) measure short wavelength (reflected) radiation, while the other four (19 through 22) measure the long wavelength (emitted) radiation. Longwave flux, Earth albedo, and net radiation are derived separately from both the WFOV and NFOV measurements
