Show moreThe CONvective TRansport of Active Species in the Tropics (CONTRAST) field campaign, was conducted using the NSF/NCAR GV research aircraft (HIAPER) to investigate the role of convective transport in TTL chemistry and the vertical distribution of the short‐lived species in the western Pacific region. The flights were based in Guam (13.48oN, 144.8oE) and occurred during January‐February 2014. These dates were designed to coordinate with flights of the Global Hawk (GH) as part of the NASA Airborne Tropical TRopopause Experiment (ATTREX) program and of the BAe‐146 as part of the NERC Coordinated Airborne Studies in the Tropics (CAST) program. The scientific objective of the TORERO project, conducted out of San Jose Costa Rica and Antofagasta, Chile was to study the release and transport of halogenated gases and oxidized VOCs in the Eastern Tropical Pacific during the season of high biologic productivity.
