Ground-level ozone, which forms photochemically in the atmosphere from precursor emissions of oxides of nitrogen (NO _x ) and volatile organic compounds, is a criteria pollutant that harms human health and public welfare. For a representative summer

We conduct the first 4D-Var inversion of NH3 accounting for NH3 bi-directional flux, using CrIS satellite NH3 observations over Europe in 2016. We find posterior NH3 emissions peak more in springtime than prior emissions at continental to national sc

We quantify the source contributions to surface PM2.5 (fine particulate matter) pollution over North China from January 2013 to 2015 using the GEOS-Chem chemical transport model and its adjoint with improved model horizontal resolution (1/4° × 5/16

Recent studies have shown that exposure to particulate black carbon (BC) has significant adverse health effects and may be more detrimental to human health than exposure to PM _2.5 as a whole. Mobile source BC emission controls, mostly on diesel-burn
