Subject: 1) Table of contents 1) Table of contents 2) Overview 3) Weather data 4) Research data 5) Miscellaneous CDs Each (major) section has a "Subject:" line, so you can search on the subject title above to find the section quickly.
Subject: 2) Overview CD-ROMs tend to be relatively expensive, but can hold as much as 600 megabytes of data. Prices may be outdated, so be sure to inquire from the provider for current prices. Prices for some discs are not known. Some discs are provided with driving software. Most of the software is for IBM-PC or compatible systems, but some is available for the Macintosh, and, increasingly, for Unix systems. Some of these listings are not for CD-ROMs, but are for floppies or tapes. These are listed here, rather than in the section on data available on other media, because they have been prepared as a package. For non-prepackaged data requests, see the data centers listed in the FAQ section Meteorology FAQ Part 3/7: Sources of research data. Commercial sources are flagged as such. Inclusion of a commercial source in this listing does not imply endorsement.

Two CD-ROMs contain all F8 SSM/I ice concentrations, 9 July 1987 - 31 December 1991. North polar files are 137202 bytes, south polar are 105922 bytes. Data are in HDF format and can be read using software from the National Center for Supercomputing Applications (NSCA), available by anonymous ftp from NCSA ( or with commercial packages such as IDL. The SSM/I is a 7-channel, 4-frequency, linearly polarized, passive microwave radiometric system: 85.5 GHz Vertical/Horizontal, 37.0 GHz Vertical/Horizontal, 22.2 GHz Vertical, 19.3 GHz Vertical/Horizontal.

Volume 7 contains all SMMR sea ice concentrations for both polar regions, plus 5 months of Tb grids for the north polar region. The Tb grids are stored as 16-bit integers; one day of Tb data is 0.27 mbytes for the north polar region, 0.21 mbytes for the south. Ice grids are stored as 8-bit integers, each file = 136192 bytes for the north, 104912 bytes for the south.

PO.DAAC has produced a set of seven CD-ROMs which contain satellite, in-situ, and model derived data pertaining to atmospheric and oceanographic parameters. Parameters include ocean currents, sea-surface temperature and salinity, air temperature and pressure, cloud, and precipitation. Software will be included. The data have been provided by agencies worldwide. (Available in June '94.) Contact: PO.DAAC, information above.

Surface Radiation Budget (SRB) Global Datasets (price not known): Contains Version 1.1 SRB shortwave products for the period March 1985 through December 1988 as produced by the World Climate Research Programme's (WCRP) SRB Satellite Data Analysis Center (SDAC). Inputs to the Version 1.1 product are results from the International Satellite Cloud Climatology Project (ISCCP) and the Earth Radiation Budget Experiment (ERBE). 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 SRB CD-ROM has been formatted and produced to work with IBM PCs, Apple Macintoshes and Unix systems with ISO-9660 CD-ROM driver support. In addition, read and display software for IBM PCs and Apple Macintoshes are available upon request. Contact: Langley DAAC User Services, MS 157B, NASA Langley Research Center, Hampton, VA, 23681-0001. (804)864-8656, SAM II Aerosol Data (no cost): Contains Stratospheric Aerosol Measurement (SAM) II data collected from October 1978 - January 1993, documentation, and read software. The SAM II instrument, aboard the Earth-orbiting Nimbus-7 spacecraft, was designed to measure solar irradiance attenuated by aerosol particles in the Arctic and Antarctic stratosphere. The scientific objective of the SAM II experiment was to develop a stratospheric aerosol database for the polar regions by measuring and mapping vertical profiles of the atmospheric exti nction due to aerosols. This database allows for studies of aerosol changes due to seasonal and short-term meteorological variations, atmospheric chemistry, cloud microphysics, and volcanic activity and other perturbations.
