Moulin distributions during 2016-2021 on the southwest Greenland Ice Sheet

This repository provides the datasets and codes accompanying the manuscript "Mapping diverse interannual moulin distributions on the southwestern Greenland Ice Sheet", currently under review for Journal of Geophysical Research - Earth Surface. The datasets include moulin distributions mapped from 10 m resolution satellite imagery during 2016-2021, while the codes reproduce the analyses and figures presented in the manuscript. Detailed discriptions are provided below.<br>00_Satellite-derived moulins: Moulins directly mapped from Sentinel-2 imagery, representing actual moulin positions;01_Snapped moulins: Moulins snapped to DEM-modeled supraglacial drainage networks, primarily used for analyses;02_Moulin recurrences: Recurring moulins determined from the snapped moulins;03_Internally drained catchments: Internally drained catchment (IDC) associated with each moulin;04_Surface meltwater runoff: surface meltwater runoff calculated from MAR for the study area, elevation bins, and IDCs; 05_DEM-derived: Topographic features modeled from ArcticDEM, including elevation bins, depressions and drainage networks;06_GWR: Variables for conducting geographically weighted regression (GWR) analysis;<br>Code_01_Mapping moulins on the southwestern GrIS.ipynb: A Jupyter Notebook to analyze moulin distributions, reproducing most of the analyses and figures presented in the manuscript using the provided datasets;Code_02_pre1_calculate Strain Rate from XY ice velocity.py: A preprocessing Python script to calculate strain rate for the GWR analysis;Code_02_pre2_calculate Driving Stress from ice thickness and surface slope.py: A preprocessing Python script to calculate driving stress for the GWR analysis;Code_02_GWR analysis.ipynb: A Jupyter Notebook to conduct the GWR analysis using the provided datasets.
