Novaggio, Switzerland: Long-term forest meteorological data from the Long-term Forest Ecosystem Research Programme (LWF), from 1996 onwards

High quality meteorological data are needed for long-term forest ecosystem research, particularly in the light of global change. The long-term data series published here comprises almost 20 years of measurements for two meteorological stations in Novaggio in Switzerland where one station is located within a natural deciduous forest stand (NOB) with Turkey oak (_Quercus cerris_; 70 yrs), sweet chestnut (_Castanea sativa_; 90 yrs) and silver birch (_Betula pendula_; 70 yrs) as dominant tree species. A second station is situated in the very vicinity outside of the forest (field station, NOF). The meteorological time series are presented in hourly time resolution of air temperature, relative humidity, precipitation, photosynthetically active radiation (PAR) and wind speed. Novaggio is part of the Long-term Forest Ecosystem Research Programme (LWF) established and maintained by the Swiss Federal Research Institute WSL.

全球变化背景下，长期森林生态系统研究亟需高质量气象数据。本次发布的长期观测数据集涵盖瑞士诺瓦焦（Novaggio）两处气象站点近20年的监测数据：其中一处站点设于天然落叶林分（NOB）内，该林分的优势树种为土耳其栎（*Quercus cerris*，树龄70年）、欧洲栗（*Castanea sativa*，树龄90年）与垂枝桦（*Betula pendula*，树龄70年）；另一处站点设于林外紧邻区域，作为野外对照站点（NOF）。本数据集的气象时间序列以小时分辨率记录了气温、相对湿度、降水量、光合有效辐射（photosynthetically active radiation，PAR）及风速等核心气象要素。诺瓦焦地区是由瑞士联邦森林、雪与景观研究所（WSL）建立并维护的长期森林生态系统研究计划（Long-term Forest Ecosystem Research Programme，LWF）的组成部分。
