ISCCP-H Data and Information

ISCCP-H Data and Information

Global Cloud Process Studies in the Context of Decadal Climate Variability: Enhancement and Continuation of Data Analysis for the International Satellite Cloud Climatology Project (ISCCP)

 

Principal Investigator: William Rossow, The City University of New York, The City College

 

The legacy dataset - ISCCP D series - production at NASA GISS ended in 2009 and is currently archived at NASA LaRC ASDC. Since then, NCEI worked with the ISCCP Principal Investigator, William Rossow, to transition the ISCCP processing to NOAA. The new processing is now available from NOAA/NCEI as the ISCCP H series.

 

There were many improvements made in the ISCCP H-series of products. These include:

Higher Resolution Input Satellite Data - ISCCP now uses input data from full-resolution
AVHRR Global Area Coverage (GAC) and ~10 km geostationary imagery—an increase from ~30
km in the ISCCP D-series.
Higher Resolution Gridded Products  - The higher resolution inputs allow 1 degree
gridded products.
Expanded Period of Record  - The H series expands the period of record to 1982–2015 and
will continue to produce updates.
Temporally Stable Atmospheric Profiles - Neural network profiles from the HIRS provide
stable retrievals during the period of record.
New Output Product - Radiances and cloud information are available at pixel-level - 10
km - globally every 3 hours.
Output Format is Network Common Data Form (netCDF).

 

Newly reprocessed ISCCP data products H (HGM, HGH, HGG, HXG, HXS) for 1982-2015 are now available from NOAA/NCEI.
