Evaluation of Reanalysis Temperature and Precipitation for the Andean Altiplano and Adjacent Cordilleras
Abstract This study compares temperature, precipitation, and other climate variables from six widely used climate reanalysis products to inform ice‐core climate proxy record calibration in the Altiplano region of the central Andes. The reanalyzes are the European Reanalysis version 5 (ERA5), Europea...
