Simulations with preindustrial (PI) and present day (PD) aerosol emissions are run for 2 years to analyze the parametric uncertainty associated with the radiative forcing from aerosol cloud interactions (ACI). New MODIS cloud fraction joint histograms are output to efficiently decompose the radiative forcing from ACI into forcing from liquid and ice-phase clouds, as well as into microphysical and macrophysical cloud responses. 161 ensemble members are generated to explore variability in the cloud response to aerosol perturbations. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png HDF5/NetCDF4 dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral CESM > NCAR Community Earth System Model U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-29 revision 23.8 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD MICROPHYSICS EARTH SCIENCE > ATMOSPHERE > CLOUDS > CLOUD RADIATIVE TRANSFER > CLOUD RADIATIVE FORCING U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-04-29 revision 23.8 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 2010-01-01T000000+00 2012-01-01T000000+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 0 https://gdex.ucar.edu/datasets/d158793/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d158793/dataaccess/ https Data Access Related Link download none asNeeded
