ISCCP D2 Monthly Means and Climatology

Selected variables from the ISCCP-D2 monthly mean dataset (new algorithm) are available here for the period July 1983 through June 2006. Also available is a climatology including monthly, seasonal and annual mean maps. Your selections may be viewed as PNG images, or downloaded to your local disk. If you are downloading data, see the browse data format description and sample FORTRAN read subroutines. These subroutines are NOT the same as the D2READ program used for the full D2 dataset. The full documentation for the ISCCP-D2 dataset is in ISCCP Documentation of New Cloud Datasets (779K).

Note: This is only a subset of the variables that are contained in the D2 dataset. The full dataset is available from our archives. The monthly mean files as well as the monthly-hourly mean files that describe the diurnal cycle are also available for each month-year from the ISCCP download site in the directory /pub/data/D2Tars.
