Release Announcement for CERES Level 2 CCCM (C3M) Product Version D2
Posted: Wed Feb 05, 2025 1:32 pm America/New_York
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 D1 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 the following data products:
Version 4-51 CALIPSO:
VFM
05kmALay
05kmCLay
05kmCPro
Version 2 MODIS Aqua Calibrated Radiance Wide Swath Subset
Version R05 CloudSat:
2B-CLDCLASS
2B-CWC-RO
2C-ICE
The CERES-derived radiative flux algorithms used were similar to those that produced Edition 4 CERES products. Filenames take the following format:
CER_CCCM_Aqua-FM3-MODIS-CAL-CS_RelD2
Currently, the daily products are available beginning with data from July 1, 2006 through December 31, 2017. However, data is missing from May 1, 2011 to June 30, 2012 while CloudSat had power issues. For the time-period starting with July 2012, CloudSat transitioned to daytime-only operation.
