The ACCLIP Science Team Meeting was held 14-17 November 2022 in Boulder. The agenda and presentations are available here.
Call for abstracts to EGU 2023 in Vienna from April 23-28, 2023: Dynamics and chemistry of the UTLS. Abstracts due 10 January 10, 2023 by 1300 CET.
The National Center for Atmospheric Research (NCAR) and the National Aeronautics and Space Administration (NASA) will conduct a jointly funded one-month campaign in Summer of 2022 in South Korea: the Asian Summer Monsoon Chemical & CLimate Impact Project (ACCLIP). Two aircraft, including the NSF/NCAR GV and NASA WB-57, are outfitted with state-of-the-art sensors. Approximately 80 scientists from the US and other international research organizations will participate in ACCLIP. The National Science Foundation funds the NCAR portion of ACCLIP, with additional funding from NOAA and the Office of Naval Research.
The Asian Summer Monsoon (ASM) is the most prominent meteorological pattern in the Northern Hemisphere summer. Persistent convection and the large anticyclonic flow pattern in the upper troposphere and lower stratosphere (UTLS) associated with ASM produce a prominent enhancement of chemical species of pollution and biomass burning origins in the UTLS.
The monsoon convection occurs over South, Southeast, and East Asia, a region of uniquely complex and rapidly changing emissions tied to its high population density and significant economic growth. The coupling of the most polluted boundary layer on Earth to the most extensive dynamical system in the summer season through the deep monsoon convection has the potential to create significant chemical and climate impacts.
An accurate representation of the ASM transport, chemical and microphysical processes in chemistry-climate models are needed for characterizing ASM chemistry-climate interactions and predicting its future impact in a changing climate.
The scientific objectives of ACCLIP are:
