Abstract
The article presents a study on the validation of the tropospheric methane (CH4) mole derived from ground-based Fourier Transform InfraRed (FTIR) (CH4) spectroscopy. It says that CH4 is important in atmospheric chemistry, affecting the oxidizing capacity of the atmosphere and serves as a precursor of tropospheric ozone (O3). The results showed that profile retrieval lets the direct estimation of the tropospheric column-averaged CH4 amounts.
