Code to prepare, homogenise and analyse digital elevation models from Mårmaglaciären and Mårmapakteglaciären, northern Sweden

Overview

Code to prepare, homogenise and analyse DEMs from Mårmaglaciären and Mårmapakteglaciären, northern Sweden.

The inputs (downloaded in the Dockerfile) consist of:

  • Uncorrected DEMs from different sources from 1959–2021.
  • Glacier outlines from 1959–2021.

The outputs are provided as separate datasets in the Bolin Centre database:

  • Corrected DEMs from 1959–2021.
  • Calculated geodetic mass balance from 1959 to 2021.

Prerequisites

  • Docker and docker-compose
  • bash, or knowledge to recreate the steps in the build.sh script.

Language

Python

File description

Call the build.sh script to build and export the results.

See run.py for the main logic in the analysis.

Most of the code exists in the marma_dems python package:

  • marma_dems.inputs: Parsing and formatting tools for reading different types of non-massbalance input data.
  • marma_dems.analysis: Tools for analysing and correcting the input data.
  • marma_dems.plotting: Graphical plotting tools
  • marma_dems.utilities: General-purpose utility functions
  • marma_dems.main: Synthesis functions that bring together the functionality in different scripts
  • marma_dems.mb_parsing: The entire logic of mass balance field data parsing.

Comments

The code can be used to reproduce the datasets by Schytt Mannerfelt (2022a, 2022b) and uses input data in the dataset by Schytt Mannerfelt (2022c).
