Initial and boundary conditions are from the Modern-Era Retrospective analysis for Research and Applications version 2 (MERRA-2). Aerosol processes are represented with the Goddard Chemistry Aerosol Radiation and Transport (GOCART) model. Atmospheric chemistry is not explicitly resolved. We use gas climatologies to produce sulfate aerosols. Aerosol emissions from fires are represented with the Fire Inventory from NCAR (FINN) version 2.5 whereas anthropogenic emissions are based on the U.S. Environmental Protection Agency National Emissions Inventory (NEI). Sea salt emissions are accounted for by the GOCART emissions. The mineral dust emissions use the GOCART model with the Air Force Weather Agency extensions (GOCART-AFWA). Soil moisture retrievals from the Soil Moisture Active Passive (SMAP) mission were inserted every 12 hours starting on April 1 2015. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png NetCDF dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral WRF-Chem > Weather Research and Forecasting Model Coupled to Chemistry U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-15 revision 23.7 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > ATMOSPHERE > AEROSOLS > SULFATE PARTICLES U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-15 revision 23.7 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 2015 2019 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 1539899.443 https://gdex.ucar.edu/datasets/d010047/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d010047/dataaccess/ https Data Access Related Link download none asNeeded
