青藏高原及周边地区气温和降水格点数据（1998-2017）

数据内容：本数据集包括1998-2017年青藏高原逐年的气温和降水格点数据，是进行气候变化及其对生态环境影响的基础性数据。数据来源及加工：源数据来自基于国家气象信息中心基础资料专项最新整编的中国地面高密度台站（2400多个国家级气象观测站）的气温和降水日值资料，对缺测站点进行预处理之后，利用ANUSPLIN软件的薄盘样条法 (TPS，Thin Plate Spline)进行空间插值，生成青藏高原及200km缓冲区空间分辨率1km的年值格点数据。数据应用：该数据可用于气候变化对生态环境影响的研究中。

Data Content: This dataset includes annual grid data of air temperature and precipitation over the Qinghai-Tibet Plateau from 1998 to 2017, which serves as fundamental data for research on climate change and its impacts on the ecological environment.
Data Sources and Processing: The source data is derived from daily air temperature and precipitation records of over 2,400 national-level ground meteorological observation stations in China, which were recently compiled under the Basic Data Special Project of the National Meteorological Information Center. After preprocessing the stations with missing observations, the Thin Plate Spline (TPS) method integrated in ANUSPLIN software was adopted for spatial interpolation, generating annual grid data with a spatial resolution of 1 km for the Qinghai-Tibet Plateau and its 200 km buffer zone.
Data Application: This dataset can be applied to studies on the impacts of climate change on the ecological environment.
