HAPPI Heatwaves 2018

This page describes data and software used in this paper: Michael Wehner, Daithi Stone, Dann Mitchell, Hideo Shiogama, Erich Fischer, Lise S. Graff, Viatcheslav V. Kharin, Benjamin Sanderson, Harinarayan Krishnan (2018) Changes in extremely hot days under stabilized 1.5oC and 2.0oC global warming scenarios as simulated by the HAPPI multi-model ensemble. https://www.earth-syst-dynam-discuss.net/esd-2017-89/

Software:

We use the cdat version of python (https://uvcdat.llnl.gov/index.html) to run these two scripts:

make_3dayaverage_from_daily.py

make_rv_ensemble.py

Data Collections:

The five HAPPI models (variable name = tasmax) can be obtained by running these bash scripts or going directly to portal.nersc.gov/c20c

download_CanAM4.sh

download_ECHAM6.sh

download_ETH_CAM4.sh

download_MIROC5.sh

download_NorESM1.sh

The CESM1 data must be obtained from NCAR ESG server https://www.earthsystemgrid.org/

Click on "CESM1 CAM5 BGC 20C + RCP8.5 Large Ensemble"

Then click on "CESM1 CAM5 BGC Large Ensemble Atmosphere Post Processed Data, Daily Averages"

Then click on "ucar.cgd.ccsm4.CESM_CAM5_BGC_LE.atm.proc.daily_ave.TREFHTMX"

This will get you to the present day simulations.

The 1.5 and 2 degree stabilization simulations are not yet publically available (March 22, 2018) but are described at http://www.cesm.ucar.edu/experiments/1.5-2.0-targets.html

Please contact NCAR directly if you require this data. The variable name is TREFHTMX.
