=========================================================================================================== README for Data from: Expanding the Design Space of Stratospheric Aerosol Geoengineering to Include Precipitation-Based Objectives and Explore Tradeoffs =========================================================================================================== This file describes the datasets used in the ESD paper: Lee, W., MacMartin, D., Visioni, D., & Kravitz, B. (2020). Expanding the design space of stratospheric aerosol geoengineering to include precipitation-based objectives and explore trade-offs. Earth Syst. Dynam., 11(4), 1051–1072. https://doi.org/10.5194/esd-11-1051-2020 Contact Information: Walker Lee, wl644@cornell.edu Doug MacMartin, dgm224@cornell.edu All files in the dataset are NetCDF (Network Common Data Form) and can be easily read in common programming languages (python, Matlab, R, NCL, C++, and others). These data are shared under a Creative Commons Attribution 4.0 International license (CC-BY 4.0, https://creativecommons.org/licenses/by/4.0/). The data are feely available for re-use, but proper attribution must be given to the original authors. The single files are named as follows: [Variable name]_Feedback.[Simulation name]_map_monthly.nc and contains the variable (with a short description) and the spatial and temporal coordinates (i.e. latitude, longitude, and time). All associated coordinates are described in each file. The variables shared are: Variable name dimensions long name units AODVISstdn 2D-map Stratospheric aerosol optical depth 550 nm day night unitless ICEFRAC 2D-map Fraction of sfc area covered by sea-ice unitless PRECC 2D-map Precipitation rate (convective) m/s PRECL 2D-map Precipitation rate (large-scale) m/s TREFHT 2D-map Reference height temperature K Data from files labeled "Precip 1" spans the 2060-2095 period. Data from files labeled "Precip 3" spans the 2061-2095 period. Simulation names in the names of files, and bundled zipped folders for download, refer to the following simulations in the EDS paper: Precip.001 = P0/ITCZ/SSI, or Sim 2 (1 ensemble member) Precip.003 = T0/ITCZ/SSI, or Sim 1 (1 ensemble member) Acknowledgments: We would like to acknowledge high-performance computing support from Cheyenne (doi:10.5065/D6RX99HX) provided by NCAR's Computational and Information Systems Laboratory, sponsored by the National Science Foundation.
