典型冰川前端气象数据集（2019-2020）

包括典型冰川（浪卡子县枪勇冰川：东经90.23°，北纬28.88°，海拔4898米，地表覆被为基岩；申扎县甲岗山冰川：东经88.69°，北纬30.82°，海拔5362米，地表覆被为碎石和杂草）2019-2020年自动气象观测数据。枪勇冰川记录包含1.5米温度、1.5米湿度、2米风速、2米风向、地表温度等数据。该自动气象站的数据采用USB离线获取的方式收集，初始记录时间为2019年8月6日19时10分，记录间隔为10分钟，2019年10月24日现场下载数据，未能连接上。2020年12月20日16:30到现场下载数据，仍然无法连接到电脑，于是将数采仪取回带到北京后将数据读出。数据未缺失，但风速数据在2020年7月14日9:30之后有问题（极可能是风向标被破坏所致）。甲岗山冰川初始记录时间为2019年8月9日15时00分，记录间隔为1分钟，电源主要是通过蓄电池和太阳能板来维持。该自动气象站无内部存储，数据每小时通过GPRS上传至HOBO网站，由专人定期下载。2020年1月5日23:34，1.5米温湿度传感器出现异常，温度和湿度数据丢失。2020年6月30日21:20之后所有数据完全无法通过网站下载。2020年12月19日将数采仪取回，下载到2020年6月23日19:43至9月25日3:36的数据。之后更换温湿度传感器，于12月21日12:27重新开始观测。目前数据由三段组成（2019.8.9-2020.6.30；2020.6.23-2020.9.25；2020.12.19-2020.12.29），经检查，数据有部分缺失，个别数据因记录电池电压，时间上有重复，需要核对。甲岗山冰川前端气象观测数据使用美国ONSET 公司HOBO RX3004-00-01型号自动气象站采集，温湿度探头型号为S-THB-M002 ，风速风向传感器型号S-WSET-B ，地温温度传感器型号S-TMB-M006 。枪勇冰川前端气象观测数据使用美国ONSET 公司HOBO U21-USB型号自动气象站采集，温湿度探头型号为S-THB-M002 ，风速风向传感器型号S-WSET-B ，地温温度传感器型号S-TMB-M006 。

This dataset contains automatic meteorological observation data from 2019 to 2020 for two typical glaciers: Qiangyong Glacier (Langkazi County: 90.23° E, 28.88° N, elevation 4898 m, surface cover: bedrock) and Jiagangshan Glacier (Shenzha County: 88.69° E, 30.82° N, elevation 5362 m, surface cover: crushed stones and weeds).

The observational records of Qiangyong Glacier include data of 1.5 m air temperature, 1.5 m relative humidity, 2 m wind speed, 2 m wind direction, surface temperature, and other related parameters. Data from this automatic weather station was collected via offline USB retrieval. The initial recording started at 19:10 on August 6, 2019, with a recording interval of 10 minutes. On October 24, 2019, on-site data download failed due to connection issues. On December 20, 2020 at 16:30, another on-site download attempt also failed to connect to the computer, so the data logger was retrieved and brought back to Beijing for data extraction. The dataset is generally complete, but wind speed data after 09:30 on July 14, 2020 are problematic, most likely due to damage to the wind vane.

For Jiagangshan Glacier, the initial recording started at 15:00 on August 9, 2019, with a recording interval of 1 minute. The power supply was mainly maintained by batteries and solar panels. This automatic weather station had no internal storage, so data was uploaded to the HOBO website via GPRS every hour, and downloaded regularly by dedicated personnel. At 23:34 on January 5, 2020, the 1.5 m temperature and humidity sensor malfunctioned, resulting in lost temperature and humidity data. After 21:20 on June 30, 2020, all data could no longer be downloaded via the HOBO website. On December 19, 2020, the data logger was retrieved, and data from 19:43 on June 23, 2020 to 03:36 on September 25, 2020 was downloaded. Afterwards, the temperature and humidity sensor was replaced, and observation resumed at 12:27 on December 21, 2020. The current dataset consists of three segments: 2019.8.9–2020.6.30; 2020.6.23–2020.9.25; 2020.12.19–2020.12.29. Post-inspection reveals partial data loss, and some individual data entries have duplicate timestamps due to battery voltage logging during recording, which require verification.

Meteorological observation data at the front of Jiagangshan Glacier were collected using an automatic weather station of model HOBO RX3004-00-01 from ONSET Corporation (USA), with the temperature and humidity probe model S-THB-M002, wind speed and direction sensor model S-WSET-B, and soil temperature sensor model S-TMB-M006. Meteorological observation data at the front of Qiangyong Glacier were collected using an automatic weather station of model HOBO U21-USB from ONSET Corporation (USA), with the same sensor models: S-THB-M002 (temperature and humidity probe), S-WSET-B (wind speed and direction sensor), and S-TMB-M006 (soil temperature sensor).
