The East Pacific Investigation of Climate Processes in the Coupled Ocean-Atmosphere System (EPIC)

Overview of the Experiment

EPIC-2001 was a combined oceanic-atmospheric field program aimed at improving our understanding of air-sea coupling processes in the east Pacific ITCZ and cold tongue regions (see scientific overview document). The intensive observation period (IOP) of the experiment was carried out from September to October 2001in the vicinity of 0-10°N, 95°W (see map). The ultimate objective of the EPIC dataset is to improve air-sea interaction and boundary-layer parameterizations in models of the ocean and the atmosphere, and to validate coupled models.

The focus of the CSU Radar Meteorology group activities in EPIC was to study convective processes in the warm pool region using the C-band radar and launching upper air soundings on-board the NOAA R/V Ronald H. Brown. EPIC participants from the CSU Radar Meteorology Group on-board the Brown included: Robert Cifelli, Walt Petersen, and Bob Bowie. Dennis Boccippio of the Global Hydrology and Climate Center at NASA MSFC also participated in the CSU group activities (click here for a group photo courtesy of J. Richards). Participation and research analyses for EPIC was supported by the National Science Foundation.
