Definition of parameter perturbations
We do not know of a neat way to download these CSVs other than going to the raw text file and copying and pasting from that in to a text editor. If the file is too large for github to format, you will see a download button. If you click download you get the raw text file. However, if the file is small, github formats it. In that case, hit “raw” to reveal the raw text.
Link to notebook on how to read CSV files that store the parameter perturbations for the following base model configurations:
- GA7
- Full set of perturbations
- [20 parameter combinations used for Yamazaki et al (2020)]
- 15 parameter combinations used for part of UKCP Global projections
- GA8
- To be finalised Dec 2020
