The Campaign
The Central Equatorial Pacific Experiment (CEPEX) was a field investigation that studied the role of cirrus radiative effects and surface evaporation in limiting maximum sea surface temperature (SST) across the Central Pacific Ocean. CEPEX consisted of one deployment from March to April 1993 in the Central Pacific Ocean. NASA ER-2, Aeromet Learjet, NOAA P-3, and NCAR Electra aircraft collected in situ and remote measurements of cloud properties, radiation, and water vapor. Shipborne and radiosonde observations were also collected. CEPEX was primarily supported by the National Science Foundation (NSF) and the Department of Energy (DoE), and NASA was only a significant participant.
