Coordinated Airborne Studies in the Tropics (CAST) Field Campaign Report

摘要: The last field campaign held at the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility site on Manus Island, Papua New Guinea (PNG), was conducted in February 2014 as part Co-ordinated Airborne Studies Tropics (CAST) campaign. This a collaboration between National Aeronautics and Space Administration (NASA), Center for (NCAR), United Kingdom’s (UK) Natural Environment Council (NERC) to study composition Tropical Tropopause Layer (TTL) impact deep convection this composition. There are three main areas interest: i) transport trace gases tropical atmosphere (especially short-lived halogenated compounds that can be lifted rapidly into TTL, where they augment stratospheric loading these species); ii) formation cirrus its TTL; iii) upper-atmosphere water vapor budget. Overall, aim improve understanding dynamical, radiative, chemical role TTL. operation joint experiment Universities Manchester Cambridge UK Centre Science (NCAS).
