3.5.2 Data Set II, Aerosol Size Spectrum

PCASP files (replaced on January 14, 2005): Contain 1 Hz size distribution data
measured aboard the Center for Interdisciplinary Remotely-Piloted Aircraft Studies
(CIRPAS) Twin Otter during the Atmospheric Radiation Program (ARM) Intensive
Operational Period (IOP) 2003 using the PCASP, with SPP-200 electronics. PCASP
is Passive Cavity Aerosol Spectrometer manufactured by PMS Inc., but with an
SPP-200 data system manufactured by DMT Inc., Ponca City, Oklahoma, USA,
was the base from which the flights were conducted. These were typically between
3 and 5 h flights, carried out during the month of May 2003. The Aerosol IOP
was conducted between May 5 and 31, 2003 over the ARM Southern Great Plains
(SGP) site. There were a total of 16 science flights, for a total of 60.6 flight hours,
conducted by the CIRPAS Twin Otter aircraft on 15 days during this period. Most
of the Twin Otter flights were conducted under clear or partly cloudy skies to assess
aerosol impacts on solar radiation.
The aerosol particle size concentrations ranging in diameter from 0.1 to
3.169701 µm (accumulation and coarse modes) were measured in 20 channels (size
ranges). The geometric mean radius of the class interval was used for computing
d(ln r an ). The data sets were obtained from ARM IOP Data Archive http://www.

3.5.3 Data Set III, Cloud Drop Size/Number Concentration

Cloud drop size/number concentration. Project SAFARI 2000, CARG Aerosol and
Cloud Data from the Convair-580. Web Site: http://cargsun2.atmos.washington.
edu/ . The Cloud and Aerosol Research Group (CARG) of the University of
Washington participated in the SAFARI-2000 Dry Season Aircraft campaign
with their Convair-580 research aircraft. This campaign covered five countries in
southern Africa from 10 August through 18 September, 2000 on the 31 research
flights. (http://daac.ornl.gov/data/safari2k/atmospheric/CV-580/comp/SAFARI-
