Indoor microclimate measurements in a modernized mountain rescue station in Podlesice, Poland (August 2025)

This dataset contains indoor thermal microclimate measurements collected in room 0/7 of the Central Rescue Station of the Jurajska Group of GOPR in Podlesice, Poland, following the modernization of the building. The indoor dataset comprises 298 observations recorded at 10-minute intervals between 8 and 10 August 2025 using a Delta OHM HD32.1 Thermal Microclimate meter. The recorded and calculated variables include wet-bulb temperature, globe temperature, indoor air temperature, barometric pressure, relative humidity, air velocity, mean radiant temperature, WBGT, PMV and PPD. A separate external air-temperature series derived from an IMGW data extract is provided at 30-minute intervals. A mechanical supply-and-exhaust ventilation system with heat recovery was installed in the building but remained inactive throughout the indoor monitoring period. The deposit includes cleaned UTF-8 CSV files, the raw instrument log, an instrument-generated report and a README file describing the variables, units, measurement uncertainties and data-processing procedure. No personal data or questionnaire responses are included.
