Abstract

This study aims to quantify the variability in CO2 transport between global scale and regional scale models during summer frontal passage events over continental US (CONUS). Atmospheric inversions typically use global chemical transport models (CTMs) to simulate the transport of CO2. These models use reanalyzed meteorology to run at coarse resolutions (3° by 2° globally) in contrast to regional scale meteorology models often running at resolutions of 10s of kilometers. Simulations of atmospheric transport of CO2 may be a function of the resolution of the numerical models employed. Studies of the synoptic scale transport of CO2 have shown that during frontal passages there is a sharp change in the atmospheric concentrations of CO2. In order to improve our knowledge of atmospheric inversion products, it is important to characterize the impact of these events on the transport of CO2 over CONUS. The NASA ACT-America 2016 Summer campaign took place between 18th July and 28th August 2016. M
