青藏高原西大滩气象要素数据集（2014-2018）

本数据集为2014-2018青藏高原西大滩（XDT）气象要素数据集。气象要素包括：2m空气温度（℃）、2m空气湿度（%）、降水（mm）、2m风速（m/s）、总辐射（w/㎡）。降水观测采用T200B。数据来源于中国科学院青藏高原冰冻圈观测研究站位于青藏线西大滩的综合监测场（场点编号：XDTMS），数据根据原始监测数据（监测频率为每半小时一次）计算日均值，缺测部分或不满足计算日均值条件的以NAN表示。数据经过人工整理及校验，缺测时段为2017-7-7至2017-10-3。

This dataset is the 2014–2018 meteorological variable dataset from Xidatan (XDT) on the Qinghai-Tibet Plateau. Meteorological variables include 2-meter air temperature (℃), 2-meter relative air humidity (%), precipitation (mm), 2-meter wind speed (m/s), and total global radiation (W/㎡). Precipitation was measured using the T200B sensor. The data were collected at the comprehensive monitoring site (site ID: XDTMS) of the Cryosphere Research Station on the Qinghai-Tibet Plateau, Chinese Academy of Sciences, located at Xidatan along the Qinghai-Tibet Railway. Daily mean values were calculated from the original monitoring records with a sampling frequency of once every 30 minutes. Missing data or data that failed to meet the criteria for daily mean value calculation are denoted as NAN. The dataset has undergone manual organization and quality validation, with the missing data period spanning from July 7, 2017 to October 3, 2017.
