中科院藏东南站：易贡基本气象数据（2020-2021）

该数据为中国科学院藏东南高山环境综合观测研究站2018年在易贡藏布流域架设自动气象站数据（AWS，Campbell公司），地理坐标为北纬30.1741，东经94.9334，海拔2282m，下垫面为草地。
数据包括气温（℃）、相对湿度（%）、风速（m/s）、水汽压（Kpa）和气压（mb）日算术平均数据和降水的日累计值，原始数据为10分钟记录一个平均值。温湿度采用HMP155A温湿度探头测定，降雨量仪器型号为TB4，大气压力传感器探头为PTB210，风速传感器为05103，这些探头离地面2 m高。数据质量方面：原始数据质量较好，缺失较少。该数据站点为青藏高原较低海拔的气象站，后续会不定期更新，可供研究气候、水文、冰川等的科研工作者使用。

This dataset comprises automatic weather station (AWS, Campbell Company) data collected in 2018 within the Yigong Zangbo River Basin, deployed by the Comprehensive Observation and Research Station for Alpine Environments in Southeastern Tibet, Chinese Academy of Sciences. The station has geographic coordinates of 30.1741° N, 94.9334° E, an elevation of 2282 m, and its underlying surface is grassland. The dataset includes daily arithmetic mean values of air temperature (℃), relative humidity (%), wind speed (m/s), water vapor pressure (kPa), and atmospheric pressure (mb), as well as daily cumulative precipitation. The raw data were recorded as 10-minute averages. Air temperature and relative humidity were measured using HMP155A probes, precipitation using a TB4 sensor, atmospheric pressure using a PTB210 sensor, and wind speed using a 05103 sensor, all installed at a height of 2 m above the ground. Regarding data quality, the raw dataset has good quality with minimal missing values. This station is a low-elevation meteorological station on the Qinghai-Tibet Plateau, and the dataset will be updated irregularly in the future. It is available for researchers studying climate, hydrology, glaciology, and other related disciplines.
