Abstract

​Within this work, we are mainly interested to explore how does the columnar CO2 content change across cold front boundaries. We used airborne lidar measurements of columnar CO2 measurements obtained during NASA-funded ACT-America (Atmospheric Carbon Transport-America) field campaign in summer 2016. Using the high-resolution measurements, we examine the nature of CO2 variation and transport inside above the convective boundary layer (CBL). In particular, we used measurements obtained by MFLL (multi-functional fiber laser lidar) onboard NASA’s C-130 aircraft. We investigate the spatial variability of columnar CO2 across the frontal boundary (i.e. warm sector versus cold sector) and compare these measurements with those taken by an in-situ instruments. The lidar measurement technique is desirable because it allows for simultaneous examination of the CBL and the FT.First, we establish a baseline spatial variation for the columnar data using measurements o
