We use the Community Earth System Model Large Ensemble 2 (LENS2) to take the 100-member ensemble mean difference between the monthly mean future (2070-2100) and historical period (1999-2021), and add that delta to the ERA5 reanalysis data that forces MPAS at boundary and initial conditions. All other aspects of this PGW simulation are the same as the historical simulations, as we use MPAS-A version 8.0.1 with a 15-3km variable mesh centered at 20 degrees North and 80 degrees West. This regional domain extends from 20 degree South to 61 degree North and from 145 degree West to 15 degree West. The inner, 3km nest covers Central America and the Caribbean, while the 15 km portion of the domain extends well into South and North America. These simulations were developed to enable research as part of the NSF NCAR Mesoamerica Affinity Group (MAAG) in collaboration with Dr. Kelly Nunez Ocasio at Texas A&M. Alongside the historic simulations, these novel PGW MPAS simulations will allow for an analysis of how warmer and moister conditions could change hurricanes, low-level jets, ITCZ, extreme rainfall, and MCSs, among other features, in this region. The dataset includes output on the native MPAS grid, for flexibility in plotting directly in using U Xarray or to use a remapping function. Namelist files for running the model are also included. 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 MODELS > MODELS U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-05-13 revision 23.9 NASA Global Change Master Directory orginator Valids List: Platforms EARTH SCIENCE > ATMOSPHERE > ALTITUDE > GEOPOTENTIAL HEIGHT EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > OUTGOING LONGWAVE RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > DEW POINT TEMPERATURE > DEWPOINT DEPRESSION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > UPPER AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > HUMIDITY > SPECIFIC HUMIDITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR INDICATORS > TOTAL PRECIPITABLE WATER EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > U/V WIND COMPONENTS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > UPPER LEVEL WINDS > U/V WIND COMPONENTS EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > WIND DYNAMICS > VERTICAL WIND VELOCITY/SPEED EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > LIQUID PRECIPITATION > RAIN EARTH SCIENCE > ATMOSPHERE > WEATHER EVENTS > Stability/Severe Weather Indices > CONVECTIVE AVAILABLE POTENTIAL ENERGY (CAPE) EARTH SCIENCE > SPECTRAL/ENGINEERING > RADAR > RADAR REFLECTIVITY EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR PROCESSES > CONDENSATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > WIND DYNAMICS > CONVECTION EARTH SCIENCE > LAND SURFACE > SURFACE THERMAL PROPERTIES > HEAT FLUX EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > UPPER AIR TEMPERATURE > POTENTIAL TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SEA LEVEL PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > WIND DYNAMICS > VORTICITY U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-05-13 revision 23.9 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 climatologyMeteorologyAtmosphere 2017-09-15T000000+00 2017-09-30T000000+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 3489844.619 https://gdex.ucar.edu/datasets/d797484/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d797484/dataaccess/ https Data Access Related Link download none asNeeded
