In the last decades, an increase in rockfalls has been documented and has been attributed to air warming and to solar radiation. However, in-situ relationship between solar radiation and rock temperature is still little known, while a comprehensive understanding of heat transfer in rocks and their thermophysical properties are crucial to rockfall risk mitigation. This issue is being investigated in the Bessanese high-elevation experimental site, that is located in the Western Italian Alps. This site is representative of the glacial and periglacial environments of the Alps and is registered in DEIMS-SDR (see https://deims.orgf8718e56fb4d-49a3-92a9-3670e7f10ee9). Solar radiation and rock temperature data collected at three different depths are available here for the scientific community.Rock temperature, RT (°C), with a measurement uncertainty of 0.03°C in the range from -20 °C to +40 °C
