Airborne Lidar Measurements of XCO₂ in Synoptically Active Environment and Associated Comparisons With Numerical Simulations.

ABSTRACT: Frontal boundaries have been shown to cause large changes in CO₂ mole-fractions, but clouds and the complex vertical structure of fronts make these gradients difficult to observe. It remains unclear how the column average CO₂ dry air mole-fraction (XCO₂) changes spatially across fronts, and how well airborne lidar observations, data assimilation systems, and numerical models without assimilation capture XCO₂ frontal contrasts (ΔXCO_2, i.e., warm minus cold sector average of XCO₂). We demonstrated the potential of airborne Multifunctional Fiber Laser Lidar (MFLL) measurements in heterogeneous weather conditions (i.e., frontal environment) to investigate the ΔXCO₂ during four seasonal field campaigns of the Atmospher
