Publication State:	published
The publication state of this metadata: 'old' - for redundant records; 'working' - for new/in progress records; 'published' - for records approaching maturity, which may still change, but should be available via the discovery services; and 'Published' for mature records that are unlikely to change and should be available via the discovery services.

Summary
A brief description of the data.

This dataset contains Version 1.1 Surface Radiation Budget (SRB) shortwave products for the period from March 1985 until December 1988 as produced by the World Climate Research Programme's (WCRP) SRB Satellite Data Analysis Center (SDAC). The data are derived from results from the International Satellite Cloud Climatology Project (ISCCP) and the Earth Radiation Budget Experiment (ERBE).

Content
The actual data being described by this document. NB, in the case of data granules, this content may just be a reference to an ingested CSML or CDML file.

Introduction

The Surface Radiation Budget (SRB) dataset comprises estimates of surface downward and net irradiances, surface albedo, downward direct / diffuse ratio, surface cloud forcing, daylight cloud fraction. Data are derived from ISCCP and ERBE satellite projects. Various other radiation, cloud, meteorological and other diagnostic parameters are also provided.

SDAC uses two methods (known as the Pinker and Staylor algorithms) to estimate surface downward and net irradiances, surface albedo, downward direct/diffuse ratio, surface cloud forcing, and daylight cloud fraction. In addition, various other radiation, cloud, meteorological and diagnostic parameters are provided to aid the user in understanding variations in the SRB parameters.

The data are archived at the NASA Langley Research Center. They are held at the BADC on the NASA CD-ROM.

Data Access

This dataset is public.

The data are held on CD-ROM at the BADC and are available for browsing purposes. If you want to use the data in earnest you should order a copy of the CD from the User and Data Services at the NASA Langley DAAC. Please ensure that you comply with the Langley DAAC Conditions of Use for this dataset.

Data availability and file format

The dataset contains 52 monthly averaged and 10 daily averaged parameters on a 280 x 280 km global grid (6596 cells). The data are stored in binary Hierarchical Data Format (HDF) files. There is also an image directory which contains browse images of various SRB, ISCCP and ERBE parameters in GIF and HDF formats.

Documentation and Links to further information and references
