Summary
A brief description of the data.

Global monthly cloud products as produced for the International Satellite Cloud Climatology Project (ISCCP) at the Goddard Institute for Space Studies in New York. The data on are the ISCCP Stage D2 data (ISCCP-D2), at 280 km spatial resolution. There are 130 variables contained within the dataset, which has both monthly means as well as means for three hourly time intervals. The data available at the time of publication begin in July 1983 and extend through to December 1999. This dataset is public.

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

CLIMATOLOGICAL SUMMARY PRODUCT (REVISED ALGORITHM)

This dataset contains the global monthly cloud products (ISCCP-D2), at 280 km spatial resolution, using a revised algorithm. There are 130 variables contained within the dataset, each of which has a total monthly mean as well a monthly mean for each of the three-hourly observation times. The data available at the time of publication begin in July 1983 and extends through to December 1999. Software to read the data is also provided.

The International Satellite Cloud Climatology Project (ISCCP) is based at the Goddard Institute for Space Studies in New York. ISCCP is sponsored by the World Climate Research Programme for the purpose of "collecting and analyzing satellite radiance measurements to infer the global distribution of cloud radiative properties and their diurnal and seasonal variations".

Access to data, Documentation and Software

Users are requested to cite the appropriate reference paper, Rossow et al. [1996], in any publication using ISCCP data. ISCCP data and software are publicly available.

The archive is divided in three major directories:

The DATA directory contains the data.
The DOCUMENT directory contains the documentation.
The SOFTWARE directory contains the source code and a compiled version of the read software.

README files in each directory offer more information about their contents.

The data files (e.g. d2_19830701) are available in HDF 4 format as described in the Data Directory Documentation.

The HDF libraries, source code and documentation can be obtained free of charge from the HDF Group .
The HDF Group also provides a variety of tools to assist in viewing, analyzing, and displaying HDF formatted data files.

Additional data, related to ISCCP, may also be transferred directly from GISS using the anonymous FTP site.

Documentation, Links to further information and references

Complete documentation on the ISCCP_D2 data set can be obtained from the ISCCP website
Also from the ISCCP home page at GISS, general information about cloud climatology can be found.

There are a number of sites on the World Wide Web which hold information about the International Satellite Cloud Climatology Project Data.

The ISCCP homepage can be found at the Goddard Institute for Space studies or GISS.

The ISCCP D1 dataset , which is the original three-hourly data from which the monthly means are constructed, is also available from the BADC.

A list of references has been compiled from the dataset documentation.

Lineage
Summary of the origins of the dataset, e.g.: "Dataset produced from NASA MODIS instrument on Terra and collected at the University of York's groundstation 1999-2003 and a copy provided to NEODC in June 2007".

Data acquired as is in 2002.

Quality Statement
