纳木错常规积雪气象数据集（2022-2023）

本气象数据集来源于在西藏自治区当雄县纳木错乡五组，念青唐古拉山北麓山脚建立的综合积雪观测站（E91°02'58'', N30°43'28'', 4848 m）测量所得，包含2022.6.28-2023.4.24期间的2 m处的气压、风速、风向、气温、相对湿度、四分量辐射，以及降水、雪深、地表温度、4层（5 cm-10 cm-20 cm-40 cm）土壤温-湿-盐数据等。该数据集采样频率为30分钟，数据质量好，无缺失或异常值，未进行任何加工。数据集可以为青藏高原积雪质能平衡、陆面过程以及陆-气耦合作用等研究领域提供数据支持。This meteorological dataset is derived from measurements conducted at a comprehensive snow observation station established at Group 5, Namco Township, Damxung County, Tibet Autonomous Region, at the northern foothills of Nyainqentanglha Mountains, with coordinates of E 91°02'58'', N 30°43'28'' and an altitude of 4848 m. The dataset covers variables including atmospheric pressure, wind speed, wind direction, air temperature, relative humidity, four-component radiation measured at 2-meter height, as well as precipitation, snow depth, surface temperature, and soil temperature, moisture and salinity data from four layers (5 cm, 10 cm, 20 cm, 40 cm) during the period from June 28, 2022 to April 24, 2023. With a sampling frequency of 30 minutes, this dataset has excellent data quality with no missing or abnormal values, and no post-processing has been performed. It can provide data support for research fields such as snow energy and mass balance, land surface processes, and land-atmosphere coupling interactions over the Qinghai-Tibet Plateau.
