Title: The 2022 Asian Summer Monsoon Chemical and Climate Impacts Project (ACCLIP)
The Asian summer monsoon Chemical and Climate Impact Project (ACCLIP) used the NSF/NCAR Gulfstream V (GV) research aircraft, the NASA WB-57f research aircraft, the Korean NARA King Air, and a broad set of balloon launches to investigate atmospheric processes that influence ozone depletion and climate in the Korea/Japan region. The WB-57 and NSF GV part of the field campaign was flown from Osan Air Base, Republic of Korea during the July-August 2022 period.
The circulation of the northern hemisphere, upper troposphere, summer is dominated by the Asian summer monsoon anti-cyclone (ASMA or oftentimes called the Tibetan anti-cyclone). This anti-cyclonic summer flow develops in response to the southern Asia monsoon, and is broadly centered on Tibet. ACCLIP was designed to examine how the ASMA influences the upper troposphere and lower stratosphere of the northern hemisphere.
The presentation will provide background on the ASMA and discuss its wider importance. In particular, I will show some of the dynamical and transport aspects during the summer of 2022. The strength and flow aspects of the ASMA will be illustrated and shown in the context of a climatology. The ACCLIP mission will be described and flight overviews will be shown. Flow fields will show detrainment events from the ASMA to the Pacific Ocean domain. Flight profiles will also show how ACCLIP made extensive sampling of the ASMA’s eastern flank – mapping of the vertical and horizontal structure in the upper troposphere and lower stratosphere.
Dr. Paul A. Newman studies the Earth’s atmosphere and, particularly, the ozone layer. He is the Chief Scientist for Earth Sciences in the Earth Sciences Division at NASA's Goddard Space Flight Center. He is also a co-chair of the Scientific Assessment Panel for the “Montreal Protocol on Substances that Deplete the Ozone Layer” - the landmark international treaty banning ozone-depleting substances to protect Earth’s ozone layer.
He earned his Bachelor of Physics at Seattle University in 1978, and his Doctorate in Physics at Iowa State University in 1984. Dr. Newman was a National Research Council postdoctoral researcher at NASA Goddard, worked for several years as science contractor, and became a NASA civil servant scientist in 1990.
Newman has authored more than 200 refereed scientific papers and reports, including several significant studies of atmospheric ozone. He helps direct Goddard's analysis of the dynamics, chemistry, and radiative properties of the atmosphere. He is a leader in aircraft use for atmospheric research, and has participated in or led more than 20 aircraft field campaigns. Dr. Newman is Vice President of the International Ozone Commission (IOC), and the past-President of the Atmospheric Sciences Section of the American Geophysical Union. He is the recipient of many awards including the American Meteorological Society’s Cleveland Abbe Award for Distinguished Service to the Atmospheric and Related Sciences (2021), the NASA Distinguished Service Medal (2017), and the Montreal Protocol’s Scientific Achievement Award (2017). He is a Fellow of both the American Geophysical Union and the American Meteorological Society.
