This dataset comprises in-situ derived snow depth (SD) measurements collected in the Sierra Nevada mountain range, Spain, from November 2023 to June 2024. The in situ measurements were derived from snow poles installed at specific locations along the mountain range. Quality control procedures included the exclusion of all NoData values and SD measurements falling outside the physical range [0, 6] m. The dataset presented here corresponds specifically to a SD automatic sensor placed the Loma Pua sector snow pole.
