The Summer 1997 SCM IOP was scheduled with the SGP97 Campaign. With
additional NASA funding, the IOP was extended so that the total IOP
covered 30 days. This IOP was been chosen for a model intercomparison
of Single-Column Models (SCMs) and Cloud-Resolving Models (CRMs)
conducted jointly by ARM and the GEWEX Cloud System Study (GCSS). In
addition, this IOP was chosen for ARM/GCSS case study since it was
convectively driven, and the period contained a wide range of
summertime weather conditions. The period was characterized by three
distinct weather segments: (1) the first segment was dominated by
local convection and frequent, heavy precipitation; (2) the next
segment was generally clear and hot; (3) the last segment was affected
by a large, convective complex with sustained precipitation. This case
study presents data from 18 June 1997 to 18 July 1997 and covers a
region from 25N to 45N latitude and from 120W to 80W longitude.
The data for this experiment is under Working Group 1 (Boundary Layer
Clouds) of the GEWEX Cloud System Study (GCSS) to improve physical
parameterizations of clouds, other boundary layer processes, and their
interactions. See: http://www.convection.info/blclouds/
The data for this experiment is also under Working Group 4 (Precipitating
Convective Cloud Systems) of the GEWEX Cloud System Study (GCSS) to
improve the parameterization of precipitating convective cloud systems
in global climate models (GCMs) and numerical weather prediction
models through an improved physical understanding of cloud system
processes. See: http://www.met.utah.edu/skrueger/gcss/wg4.html
