• The published paper can be found here: "https://doi.org/10.1073/pnas.1616020114".
• The MATLAB code can be run using the "DriverScript.m" file.
• The inversions use publicly available datasets. As such, we have not included those datasets in our tarball.
• We have included scripts to download all of the datasets though. This can be done by running the "download_data.csh" script.
• Users could also manually download the data by navigating the websites (see below), contacting the PIs for those datasets, contacting Alex Turner ([email protected]), or Christian Frankenberg ([email protected]).
• The code will still run without the original datasets and will just use the hemispheric averages that were bootstrapped from Turner et al.
• The code in the tarball is consistent with the code on the github (as of December 23, 2016).
