Snow and ice surface temperatures measured during RV POLARSTERN cruise PS149

During the Polarstern cruise PS149 from July 2025 to August 2025 in the Atlantic part of the Arctic snow and ice surface temperatures were measured using a waterproof thermometer with a needle probe during 29 ice stations. A ruler was used to determine the measuring height. In snow pits, snow and surface scattering layer (SSL) could be distinguished, thus, in the "Height, relative, from ice/snow interface [cm]" column, 0 cm indicates the snow-ice interface. These measurements included the surface and the snow-ice interface temperature. Additional temperature measurements were taken at 2 cm spacing within the snow and SSL, and at 5 cm and 2 m height above the surface. For the snow pits the total "Snow depth [m]" is also given. Apart from snow pit temperature measurements, the snow /SSL was sampled within a small (2-4 m) radius around the snow pit. Here, a ruler was used to determine the height, but a clear distinction between snow and SSL was not done or was not possible and because the SSL could potentially be penetrated by a ruler, it is a combined measurement. Thus, these measurements were taken at the "Snow+surface scattering layer, height [m]". The "Measurement_ID" column is counting the measurements per Event and is of the form n_k where n is a number for the specific vertical profile that was sampled and k indicates the measurement number at that profile.
