(06/19/2013) iii DRAFT SSF Collection Guide 6/19/2013 Preface The Clouds and the Earth’s Radiant Energy System (CERES) Data Management System supports the data processing needs of the CERES Science Team research to increase understanding of the Earth’s climate and radiant environment. The CERES Data Management Team works with the CERES Science Team to develop the software necessary to implement the science algorithms. This software, being developed to operate at the Langley Distributed Active Archive Center (DAAC), produces an extensive set of science data products. The Data Management System consists of 12 subsystems; each subsystem represents one or more stand-alone executable programs. Each subsystem executes when all of its required input data sets are available and produces one or more archival science products. This Collection Guide is intended to give an overview of the science product along with definitions of each of the parameters included within the product. The document has been reviewed by the CERES Working Group teams responsible for producing the product and by the Working Group Teams who use the product. Acknowledgment is given to Waldena Banks and Carol J. Tolson of Science Applications International Corporation (SAIC) for their support in the preparation of this document. iv DRAFT SSF Collection Guide 6/19/2013 TABLE OF CONTENTS Section Page Document
