资源简介:

This dataset contains the subsurface temperature observation interpolated at a 10 m depth compiled for the following study: Vandecrux, B., Fausto, R. S., Box, J., Covi, F., Hock, R., Rennermalm, A., Heilig, A., Abermann, J., van As, D., Bjerre, E., Fettweis, X., Smeets, P.C.J.P., Kuipers Munneke, P., van den Broeke, M., Brils, M., Langen, P.L., Mottram, R., Ahlstrøm, A.: Historical snow and ice temperature observations document the recent warming of the Greenland ice sheet, Submitted to the Cryosphere, 2023. When using this dataset please cite both the study above and the individual studies listed in the \"reference\" field. Data processing: For the temperatures continuously recorded by thermistor or thermocouple strings, the depth of each temperature sensor below the surface was calculated using installation depths and recorded surface height. Wherever necessary, we interpolated the available temperature profiles linearly to 10 m depth and allowed linear extrapolation if at least two measurements were available within 2 m of the 10 m depth. The resulting T10m values were then aggregated as monthly means if they originated from continuous measurements, or left as instantaneous values otherwise. Data structure: In the 10m_temperature_dataset_monthly.csv file, each data point has the following attributes: date: in YYY-MM-DD format site latitude longitude elevation depthOfTemperatureObservation: currently 10 m for all. May expend to all depths in future releases temperatureObserved reference: see list below reference_short note error durationOpen (for compatibility with the SUMup dataset often not known) durationMeasured: Indicate if a measurement is a monthly average or an instantaneous value method Dataset composition: Reference Start End Number of measurements Koch (1913) 1912 1913 5 Wegener (1930) 1930 1930 8 Heuberger (1954) 1950 1950 2 Benson (1962) 1954 1955 59 Schytt (1955) 1954 1954 31 Nobles (1960) 1954 1954 7 Heuberger (1954) 1954 1954 1 Meier et al.
