Summary
Remote sensing provides a basis upon for quantifying of the atmospheric composition, advancing knowledge ranging from pollution mechanisms to carbon emissions. Here, the speaker will present research progress of his group in remote sensing of aerosol, nitrogen oxide and methane. Firstly, an algorithm to retrieve absorbing aerosol optical depth from TROPOMI near ultraviolet spectrum will be introduced. Secondly, research on the application of nitrogen oxide remote sensing will be presented from improving data quality to estimating ground concentration and then to inversing emission. Finally, quantifying coal mine methane emissions by using satellite- and ground-based measurements will be introduced.
