This repository contains the code for the Basal melt rates Using Rema and Google Earth Engine (BURGEE) method. This is a method to obtain basal melt rates at high spatial resolution and is accompanied with a paper to be submitted soon.
BURGEE creates high resolution co-registered DEMs using the Reference Elevation Model of Antarctica (REMA) in combination with CryoSat-2. The DEMs can be used to to calculate surface elevation changes in both a Eulerian and Lagrangian framework, from which the latter is used to obtain high resolution basal melt rates. So far BURGEE has been tested on the Dotson Ice Shelf.
The Dotson/ folder contains the code used in Zinck et al, 2023.
The Dotson/ folder contains the scripts to
- Perform the initial co-registration.
- Perform the second co-registration.
- Calculate the Eulerian elevation change.
- Calculate the Lagrangian elevation change and the basal melt rate.
The Dotson/modules/ folder contains two scripts with functions used for the co-registration and the Eulerian elevation change, respectively.
All code is provided in javascript which can be copy-pasted and run on the Google Earth Engine
