1979-2019年青藏高原地面气象数据集（气温、降水、辐射）栅格数据集

青藏高原地面气象观测数据产品地面气象要素驱动数据集，包括近地面气温、地面降水率、短波辐射和长波辐射4个要素。方便不会使用nc格式的此类同化数据的科研人员和学生使用。在高寒网各野外站和泛第三极地区境外台站的长期观测数据基础上，建立泛第三极地区气象、水文及生态要素系列数据集；通过重点区域的强化观测与样地和样点验证，完成气象要素、湖泊水量与水质、地上植被生物量、冰川冻土变化等数据产品的反演；基于物联网技术，研制建立多站联网的气象、水文、生态数据管理平台，实现联网数据实时获取与远程控制及共享。Ground Meteorological Element-Driven Dataset for Ground Meteorological Observation Data Products over the Qinghai-Tibet Plateau encompasses four core meteorological elements: near-surface air temperature, surface precipitation rate, shortwave radiation, and longwave radiation. This dataset is developed to facilitate access for researchers and students who are not familiar with handling such netCDF-format assimilated data. Based on long-term observation data from field stations under the Alpine Network and overseas stations in the Pan-Third Pole region, a series of datasets covering meteorological, hydrological and ecological elements in the Pan-Third Pole region have been constructed. Through intensive observations in key regions and validation via sample plots and sampling points, inversion of data products including meteorological elements, lake water quantity and quality, above-ground vegetation biomass, and glacial and permafrost changes has been finalized. Leveraging Internet of Things (IoT) technology, a multi-station interconnected meteorological, hydrological and ecological data management platform has been established, enabling real-time acquisition, remote control and sharing of interconnected observation data.
