摘要
气象因子是中国生态系统研究网络(Chinese Ecosystem Research Network,CERN)定位站野外观测的重要要素之一,可为生态系统与全球变化研究、气象预报提供基础数据。四川若尔盖高寒湿地生态系统国家野外科学观测研究站(简称“若尔盖站”)是新获批建设的国内唯一的高寒湿地生态站。若尔盖站在2021年实现气象要素垂直梯度观测,对于解析若尔盖高原的气象特征和高寒湿地的生态保护具有重要意义。本数据集利用若尔盖站垂直梯度自动气象观测系统,通过《地面气象观测规范》的标准规范保障所获取数据的一致性和准确性;通过《生态系统大气环境观测规范》的相关规定进行原始数据的无效剔除,再对缺失数据进行插补以确保数据的完整性。即整理了2022年若尔盖站的梯度气象观测数据24项气象指标,共计8760条日尺度数据,具体包括距离地面2 m的大气压、降水、总辐射、光合有效辐射,距离地面2 m、6 m、12 m、16 m、20 m高度的空气温度、相对湿度、风速以及20 cm、40 cm、60 cm、100 cm、150 cm土层的土壤温度等,以期为若尔盖高原生态环境保护、揭示高原大气环境变化规律及科学研究提供数据支撑。
Meteorological factors are one of the important elements for field observation at the Chinese Ecosystem Research Network(CERN)positioning stations,which can provide basic data for the research on ecosystem and global change,and weather forecasting.Sichuan Zoige Alpine Wetland Ecosystem National Observation and Research Station(referred to as"Zoige Station")stand as the sole newly-approved domestic alpine wetland ecological station.In 2021,Zoige Station built the vertical gradient observation of meteorological elements,which is of great significance for revealing the meteorological characteristics and the ecological protection of the alpine wetlands of Zoige Plateau.We used the Zoige Station's vertical gradient automatic meteorological observation system to ensure consistency and accuracy of the data by following the standard and specifications of the Ground Meteorological Observation Specification,and eliminating invalid data according to the relevant rules of the Ecological System Atmospheric Environment Observation Specification.We then interpolated missing data to ensure data integrity.Specifically,we compiled 24 meteorological indexes totaling 8,760 entries of daily scale data of the gradient meteorological observations at Zoige Station in 2022,including atmospheric pressure,precipitation,total radiation,photosynthetic effective radiation at 2 m above ground,air temperature,relative humidity,wind speed at the heights of 2 m,6 m,12 m,16 m,and 20 m above ground,as well as soil temperature at the depths of 20 cm,40 cm,60 cm,100 cm,and 150 cm.This dataset can provide data support for the ecological environment protection of Zoige Plateauand,reveal the rules of atmospheric environment changing,and scientific research on the plateau.
