Abstract

Abstract: To expand the spatial coverage of conventional environmental monitoring and play an important monitoring and early warning role in air pollution emergencies, a drone is combined with a portable FTIR spectrometer in this work to measure the infrared spectral data of gases in the region. The data from the drone is sent to ground receiving end through a data transmission module, and then the received infrared spectra are quantitatively analyzed to invert the concentrations of various pollutant gases in the air and combined with geographic information system (GIS) technology to achieve a 3D To expand the spatial coverage of conventional environmental monitoring and play an important monitoring and early warning role in air pollution emergencies, a drone is combined with a portable FTIR spectrometer in this work to measure the infrared spectral data of gases in the region.
