This repository contains code related to Temperature Controls Erosion along Arctic Rivers by Jordan Fields, Jack Kreisler, Evan Dethier, John Perrotti, and Carl Renshaw. Datasets The primary dataset for this study was Landsat 5, 7, and 8 surface reflectance images (Collection 2). Additional datasets include: - MERIT Hydro- Arctic DEM- SRTM- HydroLAKES- ERA5-Land daily- Downscaled CMIP6 GCM Software Datasets were accessed and analyzed through Google Earth Engine. Results were exported from Earth Engine and further analyzed in R for trend analysis, statistics, and visualizations. We used the data.table package for it's speed during our data organization but created plots using ggplot. Code All code needed to reproduce the results is provided here. The purpose of and any results generated by each file are briefly described here. 1. Google Earth Engine buffer_generator Generates centroids along the Mackenzie River stream network inside the project study area. Exports MERIT_Segment_Buffers (which contains the ...
