Summary

During the IOP, 1180 sondes were launched, with 4 missing data due to weather related problems and 24 terminating before 10,000 m (10 km).

Abstract

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.
