Data for "Transient climate impacts for scenarios of aerosol emissions from Asia: a story of coal versus gas"
Introduction
These files contain output data from CESM-CAM5 climate model simulations. The simulations are described in "Transient climate impacts for scenarios of aerosol emissions from Asia: a story of coal versus gas" by Benjamin S. Grandey, Haiwen Cheng, and Chien Wang (2016), Journal of Climate, doi:10.1175/JCLI-D-15-0555.1. Please refer to the manuscript for details.
File size warning
These files are relatively large, with a total combined size of 2.5GB.
NetCDF file format
All files have been compressed using gzip. After unzipping, all files will end with ".nc", the extension for NetCDF format, a binary data format commonly used for climate model output data. These NetCDF files contain metadata which aid interpretation of the data. The metadata and data can be explored using the free Panoply software tool (http://www.giss.nasa.gov/tools/panoply/ [25-Jan-2016]).
File list
The eight files contain a subset of the output data from the CESM-CAM5 simulations described in the manuscript mentioned above:
- R45_*.nc.gz - output data for transient scenario RCP4.5, for three different initial conditions (f1, h1, h2).
- A2x_*.nc.gz - output data for transient scenario A2x.
- pR45.nc.gz - output data for prescribed-SST simulation pRCP4.5.
- pA2x.nc.gz - output data for prescribed-SST simulation pA2x.
Variable list
All eight output data files contain the following data:
- AEROD_v - aerosol optical depth.
- OMEGA500 - vertical velocity at 500hPa.
- PRECT - total precipitation rate.
- TS - surface temperature.
- U10 - windspeed at 10m.
- U925 - zonal wind at 925hPa.
- V925 - meridional wind at 925hPa.
The six output files for the two transient scenarios also contain the following variable:
- cIceF - sea-ice fraction.
The two prescribed-SST simulation output data files also contain radiative fluxes for diagnosis of radiative flux perturbations (RFPs). If pA2x-pRCP4.5 differences are calculated, these flux variables correspond to the following RFP differences:
- cFNTOA - total net RFP difference.
- FSNTOA - total shortwave RFP difference.
- cDRE - direct effect shortwave RFP difference.
- FSNTOAC_d1 - surface albedo shortwave RFP difference.
- SWCF_d1 - cloud shortwave RFP difference.
- LWCF_d1 - cloud longwave RFP difference.
