西昆仑地区古里雅冰帽重建的气象数据和物质平衡数据集（1970-2019）

该数据集包含1970-2019年校正后的西昆仑古里雅冰帽日值气象数据和重建的古里雅冰帽冷季（10-5）、消融季（6-9）和年物质平衡及其分量。日值气象数据是利用冰面实测气象数据对ERA5格点数据进行校正而得到，数据包括6004米处的气温（ºC）、相对湿度（%）、风速（m/s）、入射短波辐射（W m-2）和气压（hPa）和5491米处降水（mm）。物质平衡及其分量数据是根据能量-物质平衡模型进行重建，利用多源数据进行了验证，论证了该数据成果的合理性。数据校正方法和模型的验证可参考以下论文。

This dataset contains corrected daily meteorological data of the Guliya Ice Cap in the West Kunlun Mountains from 1970 to 2019, as well as reconstructed cold season (October–May), ablation season (June–September) and annual mass balance and their components for the Guliya Ice Cap.
The daily meteorological data were obtained by correcting ERA5 gridded data using in-situ meteorological measurements on the ice surface, including air temperature (°C), relative humidity (%), wind speed (m/s), incoming shortwave radiation (W m⁻²), atmospheric pressure (hPa) at 6004 m a.s.l., and precipitation (mm) at 5491 m a.s.l.
The mass balance and its components were reconstructed based on the energy-mass balance model, validated with multi-source data, and the rationality of this dataset has been demonstrated. Please refer to relevant papers for details on the data correction method and model validation.
The dataset is stored in Excel files.
This observational dataset is available for researchers studying climate, hydrology, glaciology and related fields.
