Synoptic and Meso Scale Variability in Greenhouse Gases across Fronts in Four Seasons

Research output: Contribution to conferencePaper

Abstract

Diverse meteorological processes associated with mid-latitude cyclones (e.g. cold and warm fronts, dry lines, meso-scale convective systems) play distinct roles in distributing atmospheric greenhouse gases (GHG, e.g., CO2, CH4) and other tracer atmospheric constituents (e.g. aerosols, water vapor, O3). However, our understanding of the horizontal structures and vertical variability in GHGs across frontal boundaries remains limited. The Atmospheric Carbon and Transport–America (ACT-America, a NASA Earth Venture Suborbital project) mission collected the first measurements of atmospheric GHGs and state variables across many different fronts within the atmospheric boundary layer (ABL) and free troposphere (FT) covering all four seasons (summer 2016, winter 2017, fall 2017, and spring 2018) in three regions of the United States (Mid-Atlantic, Mid-West, and South). By deploying two NASA aircraft (C-130 and B-200), we collected more than 850 hours of high-resolution (5s) airborne in-situ and
