First ISCCP Regional Experiment Marine Stratus
The First ISCCP Regional Experiments have been designed to improve data products and cloud/radiation parameterizations used in general circulation models (GCMs). Specifically, the goals of FIRE are (1) to improve the basic understanding of the interaction of physical processes in determining life cycles of cirrus and marine stratocumulus systems and the ... radiative properties of these clouds during their life cycles and (2) to investigate the interrelationships between the ISCCP data, GCM parameterizations, and higher space and time resolution cloud data.
To-date, four intensive field-observation periods were planned and executed: a cirrus IFO (October 13 - November 2, 1986); a marine stratocumulus IFO off the southwestern coast of California (June 29 - July 20, 1987); a second cirrus IFO in southeastern Kansas (November 13 - December 7, 1991); and a second marine stratocumulus IFO in the eastern North Atlantic Ocean (July 1 - July 28, 1992). Each mission combined coordinated satellite, airborne, and surface observations with modeling studies to investigate the cloud properties and physical processes of the cloud systems.
These data were collected during the FIRE Marine Stratocumulus experiment on San Nicolas Island, California. They are as follows: cloud base height data measured with a ceilometer; processed CLASS sounding (CSD) data up to 2 kilometers (thermodynamic data only), raw CSD recorded at 3.3 second intervals (thermodynamic data only), and raw CSD at 10 second intervals (thermodynamic and wind data).
