Spatial Distribution of Near-surface Air Temperature in the Glacierized Areas of the Tibetan Plateau
This dataset contains spatial distribution of near-surface air temperature in the glacierized areas of the Tibetan Plateau, which has been processed using meteorological observation data, thermal infrared remote sensing data and glacier boundaries from China's Second Glacier Inventory. The data covers a high-altitude area of the Qinghai-Tibet Plateau for seven glacier regions (Guliya, Aru, Naimona'nyi, Gagze, Dunde, Parlung, and XiaodongKemadi), with a spatial resolution of 30 meters, spanning elevations of 3,924-6,078 m and temperatures of -42°C to +21°C. The original temperature data were obtained from multiple sources, including thermal infrared remote sensing data from Landsat 8 (L8) and Landsat 9 (L9) Collection 2 (C2) Level 2 (L2) products, as well as ground station measurements from National Tibetan Plateau/Third Pole Environment Data Center. Missing values were reconstructed through masked nearest-neighbor interpolation, followed by spatial smoothing to minimize residual inaccuracies during the temperature field updating process. This approach (gap-filling, bias-correction, smoothing) ensured robust spatialization of near-surface air temperature data. Technical validations are detailed in Accuracy and Completeness Reports. The dataset provides temperature distributions for glacier-covered areas of the Qinghai-Tibet Plateau. This dataset is suitable for climate research, environmental monitoring, and cryosphere.
The experiment's temporal coverage is discontinuous; the eight datasets have different time ranges. The temporal coverage includes Southeastern data (2023-01 to 2023-03), Xiaodongkemadi data (2012-05 to 2015-08), and Aru, Dagze, Dunde, Guliya, Naimona'nyi, and Parlung data (all from 2019-01, with end dates ranging from 2019-10 to 2019-11).

The surface called "surface" means the lower boundary of the atmosphere. "Bidirectional_reflectance" depends on the angles of incident and measured radiation. Reflectance is the ratio of the energy of the reflected to the incident radiation. A coordinate variable of radiation_wavelength or radiation_frequency can be used to specify the wavelength or frequency, respectively, of the radiation. [CF-Standard Name]; unit: 0.01
