NERC EDS UK Polar Data Centre. https://doi.org/10.5285/eddc907c-f8e9-48c4-9f23-de0f674dbee0 This dataset presents ERA5 daily downscaled surface air temperature and snowfall from two sites next to the first ice core drilled from Cordillera Darwin, Chile. These records were presented in Tetzner et al. (2025) to study regional-to-local environmental conditions at the firn core site. These local surface air temperature and snowfall estimations suggest the icefield has been progressively exposed to surface melt conditions, but not enough to produce significant melt at the firn core site. This dataset was created with the support of the Dieter R Tetzner's National Geographic Early Career Grant 2019.

The use of this downscaling routine to generate high spatial resolution climate variables was thoroughly implemented and validated in the Cordillera Darwin Region in Temme et al. (2023). Data used in this study was generated with the same inputs as detailed in Temme et al. (2023).Temme, F., Farias-Barahona, D., Seehaus, T., Jana, R., Arigony-Neto, J., Gonzalez, I. & Furst, J. J.
