Data for "Effective radiative forcing in the aerosol-climate model CAM5.3-MARC-ARG compared to default CAM5.3"

These data accompany the manuscript titled "Effective radiative forcing in the aerosol-climate model CAM5.3-MARC-ARG compared to default CAM5.3" by B. S. Grandey, D. Rothenberg, A. Avramov, Q. Jin, H.-H. Lee, and C. Wang (in preparation). The files contain input data and output data associated with the CESM-CAM5 climate model simulations described in the manuscript.

Please also see https://github.com/grandey/p17c-marc-comparison/ for details of the experimental design, model configuration, data management, and analysis.

input_data_p17c.tar.gz, a tar archive, contains the input data files for the CAM5-MARC-ARG simulations. The tar archive also contains the scripts used to generate the emissions input data files and a readme file. The scripts and readme file can also be viewed via https://github.com/grandey/p17c-marc-comparison/tree/master/input_data_p17c/.

output_timing.tar.gz contains timing data files from the timing simulations. For an example of how these data can be used, see https://github.com/grandey/p17c-marc-comparison/blob/master/analysis_draft2017b/timing_table_draft2017b.ipynb

The p17c_*.nc NetCDF files contain a subset of the output data from the comparison simulations. These data have been converted to time-series format using PyReshaper, as described in https://github.com/grandey/p17c-marc-comparison/blob/master/manage_data/data_management.org

The file naming convention is as follows:

where

1. [SIMULATION] refers to a comparison simulation casename (e.g. "p17c_marc_2000"; see https://github.com/grandey/p17c-marc-comparison/blob/master/experimental_design.org);

2. [HISTORY_FILE_TYPE] is either "cam.h0" (monthly atmosphere data), "clm2.h0" (monthly land data), or "cice.h" (monthly sea-ice data); and

3. [VARIABLE] refers to a specific variable code (e.g. "AEROD_v" is aerosol optical depth).

For an example of how these data can be used, see analysis_cdo_nco_draft2017b.ipynb and figures_draft2017b.ipynb in https://github.com/grandey/p17c-marc-comparison/tree/master/analysis_draft2017b/.

Most of the data files are in 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. For example, the metadeta contain a description of each output variable. The metadata and data can be explored using the free Panoply software tool (http://www.giss.nasa.gov/tools/panoply/ [accessed 11-Dec-2017]).
