中科院藏东南站：嘎隆拉24k冰川基本气象数据（2020）

该数据为中国科学院藏东南高山环境综合观测研究站在嘎隆拉24k冰川的表碛区自动气象站数据（AWS，Campbell公司），地理坐标为北纬29.765°，东经95.712°，海拔3950 m。数据包括气温（℃）、相对湿度（%）、风速（m/s）、净辐射辐射（w/m2）、水汽压（Kpa）和气压（mbar）日算术平均数据，原始数据中2018年10月之前每30分钟记录一个平均值，之后为10分钟记录一个平均值。温湿度采用HMP155A温湿度探头测定，净辐射探头型号为NR01，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：春季由于积雪覆盖，辐射探头积雪结冰导致误差，已剔除。改数据可以供冰川、气象和水文等方面的科研工作者使用。该数据是已发布数据《中科院藏东南站：嘎隆拉24k冰川表碛区基本气象数据（2018-2019）》的更新，后续还会根据情况更新。

This dataset comprises automatic weather station (AWS, Campbell) data collected in the supraglacial debris-covered area of Galongla Glacier 24K by the South-East Tibetan Plateau Station for Integrated Observation and Research of Alpine Environment, Chinese Academy of Sciences (CAS). The observational site has geographic coordinates of 29.765° N, 95.712° E, and an elevation of 3950 m. The dataset includes daily arithmetic mean values of air temperature (°C), relative humidity (%), wind speed (m/s), net radiation (W/m²), vapor pressure (kPa), and atmospheric pressure (mbar). For the original raw data, 30-minute averages were recorded prior to October 2018, while the recording interval was adjusted to 10-minute averages after October 2018. All meteorological variables were measured by sensors installed at 2 m above the ground: HMP155A probes for air temperature and relative humidity, NR01 sensors for net radiation, PTB210 sensors for atmospheric pressure, and 05103 anemometers for wind speed. Regarding data quality, errors caused by snow accumulation and icing on the net radiation sensors during spring due to snow cover have been removed from the dataset. This dataset is available for researchers engaged in glaciology, meteorology, hydrology and other related fields. It is an updated version of the previously published dataset "South-East Tibetan Plateau Station, CAS: Basic Meteorological Data from the Supraglacial Debris-Covered Area of Galongla Glacier 24K (2018–2019)", and will be further updated as appropriate. When using this dataset, please clearly indicate that it is sourced from the South-East Tibetan Plateau Station for Integrated Observation and Research of Alpine Environment, CAS.
