Abstract
Design of Inversion Procedure for the Airborne CO<sub>2</sub>-IPDA LIDAR: A Preliminary Study
Highlights
THE increase in anthropogenic carbon emissions since the Industrial Revolution has led to considerably elevated atmospheric CO2 concentrations and is considered as an important contributor to climate change [1]
We found that the XCO2 obtained by integrated path differential absorption (IPDA)-LIDAR was highly sensitive to xCO2 variations in the lower troposphere
An initial version of the data-processing frameworks was developed to assess the validity of the observations acquired by the IPDA LIDAR automatically and to further obtain XCO2 retrievals
Summary
THE increase in anthropogenic carbon emissions since the Industrial Revolution has led to considerably elevated atmospheric CO2 concentrations and is considered as an important contributor to climate change [1]. The novel data provide insights into the carbon cycle and climate change [11,12,13,14] These missions cannot obtain effective observations at high latitudes, at night, in heavy pollution, and under cloudy conditions owing to the intrinsic shortcomings of the passive remote sensing technique [15, 16]. A thermal infrared detector uses thermal infrared radiation to perform atmospheric CO2 detection, whereas the radiation of ground and lower atmosphere in the thermal infrared band is very similar It can obtain the CO2 concentration information only in the middle and upper atmospheres and is very insensitive to the CO2 concentration in the atmosphere at the bottom of the troposphere.
