Emissions inventories provide information on pollutants’ mass contributions and emission characteristics during a given period for sources located in a geographic area. Researchers further transform them into model-ready files that are input to air quality models by aggregating emission rates for each pollutant and source in a computational domain. As such, emissions inventories used in air...
A data assimilation method combined with machine learning has been developed and applied to adjust anthropogenic emissions and improve forecasting accuracy in Chinese unified atmospheric chemistry environment (CUACE) model. This is an attempt to combine data assimilation and machine learning. Nudging method was used to create the database of nudging gain matrixes, using simulations of CUACE...
Seasonal open biomass burning contributes to significant carbonaceous aerosol loading over South Asia. This study analyzes long-term trends in emissions in two hot spot regions, Myanmar and Punjab, based on data from the Global Fire Emissions Database (GFED4s) and Fire INventory (FINN) from the National Center for Atmospheric Research (NCAR). Our analysis reveals that emissions during active...
The dispersion patterns and arrival times to the Mexican coast of the Gulf of Mexico (GoM) of atmospheric pollutants that would result from surface oil burns are studied using the WRF and FLEXPART models. Dispersion scenarios are analyzed under different meteorological conditions in the GoM basin: sea-breeze days (for winter, spring, summer, and autumn), cold fronts (Nortes), southerly wind,...
