Point Source Carbon Dioxide Emission Monitoring Using Radiative Transfer Simulations and AVIRIS-NG Data

The significant amount of Carbon Dioxide (CO2) emission causes radiative forcing in the atmosphere that increases the earth's temperature. To reduce the emission from anthropogenic activity, it is important to monitor the major sources and sinks of atmospheric CO2 such as coal-fired Thermal Power Plant (TPP). Airborne hyperspectral sensors with contiguous spectral bands have capabilities to measure point source CO2 emission. In this study, we have estimated CO2 concentration using Radiative Transfer (RT) simulations and Airborne Visible/InfraRed Imaging Spectrometer - Next Generation (AVIRIS-NG) data acquired on Maithon TPP at Jharkhand in India. Due to its higher sensitivity to the boundary layer atmosphere, the Short-Wave InfraRed (SWIR) region is most suitable for the detection of CO2 emission sources. we used a $2.0 \mu \mathrm{m}$ absorption band for CO2 plum detection. This paper describes the Continuum Interpolated Band Ratio (CIBR) method for measurement of CO2 concentration in the atmosphere which is emitted by TPP.
