Efficacy of Regional Air Quality Policies in China

China implemented aggressive emission controls in Autumn-Winter 2017-2018 in the Beijing-Tianjin-Hebei (BTH) region in North China to curb poor air quality in winter. Here we use the national monitoring network, satellite observations, and the GEOS-Chem chemical transport model to assess the efficacy of these emission controls.
