cussh-py

Python codebase for CUSSH project funded by UEA PVC award 2023.

Contents

• load-cussh-isimip-metadata.py - python reader to load in downloaded netCDF-4 ISIMIP climate model ensemble members and extract metadata
• load-cussh-isimip-timeseries.py - python reader to load in downloaded netCDF-4 ISIMIP climate model ensemble members and extract timeseries per variable per experiment across models
• load-cussh-isimip-timeseries-combined.py - python code to load in ISIMIP experiment .pkl files and combine historical and SSP projections and apply Gaussian filter to 90% C.I.
• load-cussh-cmip6-metadata.py - python reader to load in downloaded netCDF-4 CMIP6 climate model runs for TAS and PR and extract metadata
• load-cussh-cmip6-timeseries.py - python reader to load in downloaded netCDF-4 CMIP6 climate model runs for TAS and PR and extract timeseries per variable per experiment across models
• load-cussh-cmip6-timeseries-combined.py - python code to load in CMIP6 experiment .pkl files and combine historical and SSP projections and apply Gaussian filter to 90% C.I.
• merge_netcdfs.py - python script to merge CMIP6 run fragments along the time dimension (overcomes CDO mergetime fail error)
• merge_stats.py - python script to merge the 30-yr climatological period stats from the ISIMIP and CMIP6 variable runs into single, sorted spreadsheets
• downscale-nc-single_dir.sh - bash script to interpolate ISIMIP model runs from their native resolution to the CRU TS 0.5 degree resolution (single directory version)
• compress_nc.sh - bash script to compress model run archives

The first step is to clone the latest cussh-py code and step into the check out directory:

$ git clone https://github.com/patternizer/cussh-py.git
$ cd cussh-py

Usage

The code was tested locally in a Python 3.8.11 virtual environment.

$ python downscale-nc-single_dir.sh
$ python load-cussh-isimip-metadata.py
$ python load-cussh-isimip-timeseries.py
$ python load-cussh-isimip-timeseries-combined.py
$ python load-cussh-cmip6-metadata.py
$ python load-cussh-cmip6-timeseries.py
$ python load-cussh-cmip6-timeseries-combined.py
$ python merge-stats.py

Observations and projection source data extracted from C3S CDS are available on request. Example plots (updating) are in the /PLOTS directory.
