for this dataset we ran WRF-Chem 3.9.1 (https://www2.acom.ucar.edu/wrf-chem)
RESEARCH OVERVIEW:
We develop a new, wind-driven lake spray aerosol (LSA) emissions parameterization that resolves both particle size and chemical composition, and investigate the impact of these emissions on regional chemistry in the Great Lakes region. We conduct WRF-Chem simulations for November 2015, a time period with high LSA emissions. LSA particles emitted from the surface of the Great Lakes increase particulate NO3 by 46% over the Great Lakes and by 16% over land, primarily due to heterogeneous reactions between CaCO3 and HNO3. Cations emitted from lake spray affect the thermodynamic equilibrium, reducing particulate NH4 by 42% over the Great Lakes and by 6% over the surrounding land. This also influences gas-phase species in the region, decreasing nitric acid by up to 71% over lakes. Overall, these simulations suggest that understanding LSA and its impact on other air pollutants is important for determining health and climate effects in the Great Lakes region.
Anahita Amiri-Farahani, Allison L. Steiner and Andrew P. Ault conducted the research. It took place at university on Michigan. Funding for this project was provided by the University of Michigan Cooperative Institute for Great Lakes Research (CIGLR), through the National Oceanic and Atmospheric Administration (NOAA) Cooperative Agreement NA17OAR4320152.
METHOD:
This dataset is the output of WRF-Chem model for several simulations, the format of data (*.nc, wrfout*, and wrfchemi*) is NETCDF, to read the data there are several programming languages including Python and NCL.
This dataset also contains GRIB (*.grb2) files which are read by the WRF-Chem model.
