This dataset contains in-situ temperature (T) measurements collected in the Sierra Nevada mountain range, Spain, from March to May 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 temperature automatic sensors placed in the Borreguiles del Dílar sector snow pole at different heights.
