We used CAM-chem at 0.9 degree by 1.25 degree horizontal resolution simulation with 32 vertical levels. Temperatures, and winds are adjusted to MERRA2 reanalysis fields with a 12 hour relaxation (10%). Data is saved as instantaneous fields every 6 hours into daily files. Chemistry is the MOZART-T1 mechanism. Descriptions of all simulated species are available online. We use the MAM4-VBS scheme to model aerosols. Anthropogenic emissions are from CAMS V5.1. Biogenic emissions are from online MEGAN2.1. The fire emissions are from QFED CO2 fields combined with emission factors collated for the FINN inventory to create all the emissions necessary for the CAM-chem simulation. Online ocean DMS emissions are used. onGoing datahelp@ucar.edu pointOfContact irregular dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png NetCDF NetCDF4 dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral CAM-chem > Community Atmosphere Model with 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 > ATMOSPHERIC TEMPERATURE > UPPER AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > UPPER LEVEL WINDS 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 grid 1.25 eng utf-8 climatologyMeteorologyAtmosphere -180.0 180.0 -90.0 90.0 2001-01-01T0000+00 2023-01-01T0000+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 16401378.6 https://gdex.ucar.edu/datasets/d313008/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d313008/dataaccess/ https Data Access Related Link download none asNeeded
