Dataset
Andes glaciers and ice caps outlines during the Little Ice Age (LIA)
Abstract
This dataset comprises a shapefile of >5500 outlines of glaciers and ice caps during the Little Ice Age (LIA) approximately 1400 to 1850, spanning across the Andes from the equator to -60 degrees South. These outlines have been manually digitised by reshaping Randolph Glacier Inventory version 6 (RGI_v6) (https://doi.org/10.7265/4m1f-gd79) outlines to the extent interpreted to best represent the LIA. The LIA extent was deduced manually-visually by interpreting geomorphological evidence; primarily moraine crests and trimlines, within high-resolution aerial imagery; primarily WorldView and GeoEye. More methodological details and usage of this dataset for analysis of glacier area changes from the LIA to post year 2000 are presented in the parent paper: Carrivick et al., 2024. Accelerating glacier area loss across the Andes since the Little Ice Age. Geophysical Research Letters (submitted).
