title: Data for "Radiative effects of inter-annually varying versus inter-annually invariant aerosol emissions from fires"

description: <b>Introduction:</b> These files contain CESM-CAM5 climate model emissions and output data. The simulations are described in <i>"</i><i>Radiative effects of inter-annually varying versus inter-annually invariant aerosol emissions from fires"</i> by B. S. Grandey, H.-H. Lee, and C. Wang, <i>Atmos. Chem. Phys. Discuss.</i>, doi:10.5194/acp-2016-599. Please refer to the manuscript for details. <b>File size warning:</b> These files are relatively large.<b>NetCDF file format:</b>The atmosphere output files have been compressed using gzip. After unzipping, the files will end with ".nc", the extension for NetCDF format, a binary data format commonly used for climate model input and 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-July-2016]). <b>Atmosphere output data files (bb*_o2000.nc.gz):</b>The 15 gzipped NetCDF files (bb*_o2000.nc.gz) contain data derived from the atmosphere output files of the prescribed-SST simulations described by Grandey et al. (2016):- <i>bb0_o2000</i> corresponds to simulation F0.- <i>bb1997_o2000</i> corresponds to simulation F1997, <i>bb1998_o2000</i> corresponds to simulation F1998 etc.. These ten simulations are referred to as the {Fyyyy} ensemble.- <i>bb9706_o2000</i> corresponds to simulation FMEAN.- <i>bc9706_o2000</i> corresponds to simulation BMEAN.- <i>oc9706_o2000</i> corresponds to simulation OMEAN.- <i>so9706_o2000</i> corresponds to simulation SMEAN. <b>Atmosphere output data variables:</b>The output data files contain the following variables analysed by Grandey et al. (2016):- cFNTOA - total net (shortwave plus longwave) top-of-atmosphere flux, used to calculate total net RFP differences.- <i>SWCF_d1</i> - clean-sky shortwave cloud forcing, used to calculate cloud shortwave RFP differences.- <i>LWCF_d1</i> - clean-sky longwave cloud forcing, used to calculate cloud longwave RFP differences.- <i>cDRE </i>- solar flux minus clean-sky solar flux, used to calculate direct effect RFP.- <i>FSNTOAC_d1 - </i>clean-sky clear-sky solar flux, used to calculate surface albedo RFP.- <i>PRECL</i> - large-scale precipitation rate.- <i>PRECC</i> - convective precipitation rate.- <i>cPRECT</i> - total precipitation rate.- <i>pom_a1_SRF</i> - surface organic carbon concentration.- <i>CLDHGH</i> - high cloud fraction.- <i>TGCLDIWP</i> - grid-box-average ice water path.<b>Snow cover output data (snow.tar.gz):</b><i>snow.tar.gz</i> contains a folder containing two files. These two files, derived from the land output files, contain the fractional snow cover data for the F0 (<i>bb_o2000</i>) and the FMEAN (<i>bb9706_o2000</i>) simulations.<b>Emissions files (emissions_mam3.tar.gz):</b><i>emissions_mam3.tar.gz</i> contains a folder of the modified MAM3 emissions files used to drive the 15 simulations (see "Atmosphere output data files" above). In addition to the emissions files, the folder also contains the <i>user_nl_cam</i> namelist files used to configure the CAM5 model. The <i>user_nl_cam</i> files (which are in plain text format) show which emissions files were to used to drive each simulation. The <i>user_nl_cam</i> files also refer to standard CESM-CAM5-MAM3 emissions files (not included here).<b>Contributions:</b> B.S.G. designed the experiment, performed the simulations, analysed the data, wrote the manuscript (Grandey et al., ACPD, 2016), and uploaded the data to Figshare. H.H.L. and C.W. contributed to the experimental design, analysis methodology, and redrafting of the manuscript.<b>Acknowledgements:</b>This research was supported by the National Research Foundation (NRF), Prime Minister's Office, Singapore under its Campus for Research Excellence and Technological Enterprise (CREATE) programme.
