The Atmospheric Radiation Measurement (ARM) Program conducted a Cloud Intensive Operational Period (IOP) in March 2000 that was the first-ever effort to document the 3-dimensional cloud field from observational data. Prior numerical studies of solar radiation propagation through the atmosphere in the presence of clouds have been limited by the necessity to use theoretical representations of clouds. Three-dimensional representations of actual clouds and their microphysical properties, such as the distribution of ice and water, had previously not been possible because instrumentation appropriate to the task was not available.
The data presented here are from 1 March 2000 to 31 March 2000 and cover a region from 25N to 45N latitude and from 120W to 80W longitude.
Selected variables from the SSM/I are available here for display as GIF images, or for downloading to your local disk. If you are downloading data, please see the browse data format description. Also take note of the version and reference information. The full documentation for the SSM/I data can be found at the SSM/I webpage.
If you are downloading multiple files, please use the GCSS-DIME ftp site (ftp gcss-dime.giss.nasa.gov/pub/ARM-00/SSMI).
SSM/I data and images are produced by Remote Sensing Systems and sponsored by the NASA Pathfinder Program for early Earth Observing System (EOS) products.
