First ISCCP Regional Experiment (FIRE) Arctic Cloud Experiment (ACE) CFD Data

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 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. Aerosol data obtained by Colorado State University during May 1998 on the NCAR C-130 research flights as part of the First ISCCP Regional Experiment (FIRE3) Arctic Cloud Experiment (ACE) flown onboard the NCAR C-130 aircraft during the FIRE ACE field campaign. The data are in ASCII format. The primary measurements were of ice nuclei and condensation nuclei.
