CPEX-CV

Convective Processes Experiment - Cabo Verde

The Convective Processes Experiment - Cabo Verde (CPEX-CV) was a NASA campaign that focused on studying atmospheric dynamics and marine boundary layer properties within the tropical East Atlantic region. CPEX-CV consisted of one deployment during September 2022 and operated out of Sal Island, Cabo Verde. 

NASA’s DC-8 aircraft was equipped with several instruments that collected measurements of tropospheric aerosols, winds, and precipitation. 

CPEX-CV was a continuation of the CPEX - Aerosols and Winds (CPEX-AW) campaign that took place in September 2021 in St. Croix.
