Title:	Monitoring air pollutant and greenhouse gas emissions from space
Abstract:	Robust predictions of air pollution and climate forcing require better representations of air pollutant and greenhouse gas emissions than we have at present. In this presentation, I will show how we apply satellite observations, an atmospheric chemical transport model, and statistical methods to estimate the sources of major air pollutants and a greenhouse gas. In the first section, I will discuss how we improve the spatial distribution, trend, and sectoral contribution of the emissions of nitrogen oxides (NO x ), sulfur dioxide (SO 2 ), and carbon monoxide (CO). In th second part, I will apply satellite observations to explain the trend and recent surge of global methane (CH 4 ) concentration in 2020 and 2021. In the last section, I will show the impact of international and interstate transport on ozone (O 3 ) exceedances in Yuma, Arizona. Understanding the sources and evolution of these gases is essential for developing effective air quality and climate change regulations.
