Dec. 13, 2021, 2:12 p.m.

Project: CERES

The Radiation Budget Science Project (RBSP)/CERES mission team announces the release of a new version of the CERES Level 2 (L2), CALIPSO-CloudSat-CERES-MODIS (CCCM or C3M) product. This new data product is a revised version of the publicly available B1 version of the CCCM product. The CCCM product files report CALIPSO-, CloudSat-, and MODIS-derived cloud profiles; CALIPSO- and MODIS-derived aerosol profiles; and CERES-derived, top-of-atmosphere observed radiative fluxes and computed radiative flux profiles. Cloud and aerosol profiles are derived using Version 4 CALIPSO, Version 2 MODIS Aqua Calibrated Radiance Wide Swath Subset and R05 CloudSat data products. The CERES-derived radiative flux algorithms used were similar to those that produced Edition 4 CERES products. Filenames take the following format:


Currently, the daily products are available beginning with data from July 1, 2006 through April 30, 2011. Additional data files for the time-period when CloudSat transitioned to daytime-only operation will be added eventually.

Information about this new data product, including data availability, user documentation and quality statements, relevant links, and tools for working with the data, etc. can be found at the following Atmospheric Science Data Center (ASDC) link:
