Description:
Climate variations on seasonal-to-decadal (S2D) timescales can have enormous social, economic, and environmental impacts, making skillful predictions on these time scales an invaluable tool for policymakers and stakeholders. Such variations modulate the likelihood and intensity of extreme weather events including, tropical cyclones (TCs), heat waves, winter storms, atmospheric rivers (ARs), and floods, which have all been associated with (1) increases in human morbidity and mortality rates; (2)…

Description:
This dataset includes ensemble prediction experiments using the CESM2 model. These are "perfect model prediction experiments" in which the simulations are initialized with nearly identical conditions from CESM2 historical simulations in the year 2010 and then integrated forward for two years. Ensemble prediction sets are initialized on January 1, March 1, May 1, July 1, September 1, and November 1. Five different initial conditions, taken from five different CESM2 historical simulations, are us…

Description:
Two high-resolution versions of a coupled Earth system model (CESM1.3: 0.25 degree atmosphere, 1 degree ocean; CESM1.1: 0.25 degree atmosphere, 0.1 degree ocean) are compared to the standard resolution CESM1.1 and CESM1.3 (1 degree atmosphere, 1 degree ocean). The CESM1.3 versions are documented, and the consequences of model resolution, air-sea coupling, and physics in the atmospheric models are studied with regards to storm tracks in the Southern Hemisphere as represented by 850 hPa eddy kine…

Description:
A global dataset of meteorological forcings has been developed that can be used to drive models of land surface hydrology. The dataset is constructed by combining a suite of global observation-based datasets with the NCEP/NCAR reanalysis. Known biases in the reanalysis precipitation and near-surface meteorology have been shown to exert an erroneous effect on modeled land surface water and energy budgets and are thus corrected using observation-based datasets of precipitation, air temperature an…

Description:
This dataset contains hourly observations and summary of day
information from Australian observing stations generally from
1957 to 1982, but some data go back as far as 1939.

Description:
The Dynamical Core Model Intercomparison Project (DCMIP) in 2016 focused on non-hydrostatic global models, physics-dynamics coupling, and variable-resolution modeling. The required test cases including moist baroclinic wave with terminator chemistry, idealized tropical cyclone and supercell scenarios. The intercomparison results are archived and used to establish new atmospheric model test cases of intermediate complexity incorporating simplified physics parameterizations for global climate an…
Dataset ID:
d580007
Description:
Hourly output is provided from the WACCM-X simulation with specified dynamics via GEOS5. The resolution is 0.9 x 1.25 in geographic latitude and longitude, respectively. At the high latitudes in the ionosphere the Heelis electric field is prescribed. The output includes the neutral wind, temperature and composition, plasma characteristics, ionospheric conductivities and electric field.
Some technical details are that the surface and 3D emissions cycle through 2010, and no EPP flux is specified.…

Description:
This dataset includes climate model output data from NCAR's Community Earth System Model (CESM) CMIP 5 runs, configured as CCSM4 (CAM4), with output fields for the 3-D global atmosphere at six hourly intervals. A basic set of parameters is provided on 26 model hybrid level surfaces: specific humidity, temperature, wind components, and geopotential height to support regional modeling studies. Additional parameters are provided on single level grids to support analysis studies including surfac…

Description:
The CESM Paleoclimate Working Group at NCAR conducted a series of Last Millennium community experiments, referred to as the Last Millennium Ensemble (LME). The LME used a ~2-degree atmosphere and land, ~1-degree ocean and sea ice version of CESM1 (CAM5). Ensemble members extend from 850 to 2006 using reconstructions for the transient evolution of solar intensity, volcanic emissions, greenhouse gases, aerosols, land use conditions, and orbital parameters, together and individually. We have compl…

Description:
The National Oceanography Centre Southampton (NOCS) Version 2.0 Surface Flux Dataset is a monthly mean gridded dataset of marine surface measurements and derived fluxes constructed using optimal interpolation. Input for the period 1973 to 2006 are ICOADS Release 2.4 ship data, the update from 2007 to 2014 uses ICOADS Release 2.5 and data after 2007 are preliminary. The dataset is presented as a time series of monthly mean values on a 1 degree area grid. The quality of the gridded data is q…
