Clouds and the Earth's Radiant Energy System (CERES) Energy Balanced and Filled (EBAF) Data Set Abstract |
|
The EBAF product provides monthly mean top-of-atmosphere (TOA) radiative fluxes constrained such that the 5-year average global net TOA flux is consistent with our best estimate of heat storage in the Earth-atmosphere system (~0.9 Wm-2). CERES EBAF is primarily intended for studies that use Earth Radiation Budget (ERB) data for climate model evaluation, estimating the Earth's annual global mean energy budget, and in studies that infer meridional heat transports. The CERES EBAF dataset is a single file in netCDF format. It consists of monthly 1° regional, zonal, and global averages of TOA longwave (LW), shortwave (SW), and net (NET) fluxes under clear and all-sky conditions. It is derived from the Terra SRBAVG-GEO Edition2D_rev1 and SSF Edition2B_rev1 data products.
Temporal coverage for the EBAF Terra Edition1A data set is from March 2000 through October 2005.
Information about the CERES products, including products available, documentation, relevant links, sample software, tools for working with the data, etc. can be found at the CERES data table.
The CERES Data Management Team and the Atmospheric Sciences Data Center (ASDC) at Langley use a Sampling Strategy, a Production Strategy, and a Configuration Code (CCode) to track versions of CERES primary data products. In general, minor reprocessing changes are tracked by increasing the Configuration Code while major reprocessing changes result in a new Production Strategy. The Sampling Strategy identifies the satellite and instruments which acquired the data in the product
There are currently no changes or modifications to report.

The requested form of acknowledgment for any publication in which these data are used is:
"These data were obtained from the NASA Langley Research Center Atmospheric Science Data Center."
The Langley Data Center requests a reprint of any published papers or reports or a brief description of other uses (e.g., posters, oral presentations, etc.) of data that we have distributed. This will help the Data Center determine the use of data distributed, which is helpful in optimizing product development. It also helps us to keep our product related references current.
The CERES Team has gone to considerable trouble to remove major errors and to verify the quality and accuracy of these data. Please provide a reference to the following paper when you publish scientific results with the CERES data:
