glacial-SPEI

Code to quantify the effect of including glacial runoff in Standardized Precipitation Evapotranspiration Index (SPEI).

Collaborators

• Sloan Coats (University of Hawaii)
• Jonathan Mackay (British Geological Survey)
• Lizz Ultee (Middlebury College)

What's included

This repository includes MATLAB code, used to calculate the SPEI for each climate model, scenario, and basin; and Python code, used to analyse the SPEI data. The Jupyter notebook "SPEI-analysis.ipynb" guides users through an analysis of SPEI with/without glacial runoff for any basin of choice.

Organization

The main repo contains all analysis scripts. In subfolders are:

• archived: older scripts used to develop parts of the analysis that may have been superseded
• data: all data required to reproduce our results
• SPEI_computation: code used to produce the basin-total SPEI data from output of GCMs and the glacier model
