Spring SCM IOP

27 April 1998 - 17 May 1998

Lead Scientist: David Randall

Observatory: sgp, sgp

The Spring 1998 SCM/Cloud IOP was conducted from 27 April to 17 May 1998 at the ARM SGP site. All objectives outlined in the planning document were addressed to some degree. As is typical of mid-spring in Oklahoma, the meteorology was quite varied ranging from cold rain to severe thunderstorms to clear and hot. The majority of the period was clear, however.

The goals of the IOP included:

  • Intensive observations of cirrus clouds with in situ aircraft and surface-based and space-based remote sensors
  • Resolution of MMCR calibration uncertainty
  • In situ sampling of airborne insects that are causing non-cloud echoes in the MMCR radar data. (Summary of CU Kite-Borne Activities (Insect Studies) (pdf file))
