Description
Summary:This dataset comprises of codes (written in MATLAB) and gridded files (exported as GeoTIFF) presented in Bodart et al. (2023; The Crysophere; https://doi.org/10.5194/tc-2022-199). A summary of the key findings from this study is provided as follows: "Using a spatially extensive IRH over Pine Island Glacier, Thwaites Glacier, and Institute and Möller Ice Streams (covering a total of 610 000 km2 or 30% of the WAIS), and a local layer approximation model, we infer mid-Holocene accumulation rates over the slow-flowing parts of these catchments for the past ~4700 years. By comparing our results with modern climate reanalysis models (1979 – 2019) and observational syntheses (1651 – 2010), we estimate that accumulation rates over the Amundsen-Weddell-Ross divide were on average 18% higher during the mid-Holocene than modern rates. However, no significant spatial changes in the accumulation pattern were observed." This dataset contains a series of files (5x .m files, 10x .tif files). The numbering of the figures in ... : {"references": ["Bodart, J.A., Bingham, R.G., Young, D.A., MacGregor, J.A., Ashmore, D.W., Quartini, E., Hein, A.S., Vaughan, D.G. and Blankenship, D.D., 2022.
