ISCAT-1998-South-Pole-aerosol-Observations
Listed in NASA Earthdata CMR
The 1998 - 1999 ISCAT South Pole observational data are available on one CD-ROM.
Description
The aerosol data, trace gas data, and photolyitc rate coefficients are separated into three directories: Aerosol, TraceGases, and j-values. In the Aerosol directory, there are two sub-directories containing ASCII data files and corresponding readme files describing the data format, measurement techniques, precisions and accuracies, and detection limits.
One subdirectory has the aerosol size distribution data, and another one provides filter measurements of aerosol ions and nuclides. Some of the detailed description of project ISCAT can be found in the special section in GRL October 1, 2000. The ISCAT data CD is available by contacting Douglas D. Davis: Dr.

Davis 221 Bobby Dodd Way School of Earth and Atmospheric Sciences Georgia Institute of Technology Atlanta, GA 30332 Phone: 404-894-4008 Fax: 404-894-1998 E-mail: dd16@prism.gatech.edu The ISCAT 1998 field observations went from early December 1998 to early January 1999 at the South Pole. All aerosol data was collected from the roof of the Atmospheric Research Observatory (ARO) building. The aerosol filter sampling line was about 13 meter above the snow surface and extended 1 - 2 m from the building facing the prevailing wind.
This typically was out of the "clean air sector" (0 - 120?, e.g., see Davis et al. [2001]). The aerosol size distribution measurement samples were collected from the NOAA stack on the roof of the ARO building, about 16 m above the snow surface.
