Meteorological data collected at Grizedale (1995-2009)

In response to widespread concern that air pollution could affect forest condition, the International Co-operative Programme on the Assessment and Monitoring of Air Pollution Effects on Forests (ICP forests) was established under the UN/ECE Convention on Long-range Transboundary Air Pollution (CLRTAP) in 1985. ICP Forests was mandated to monitor air pollution effects on forests and to contribute to a better understanding of cause-effect relationships.
Within the complex of anthropogenic and natural stresses, air pollution continues to be regards as an important stress factor. Air pollution and its effects on forest ecosystems are complex and difficult to isolate and quantify. A large number of other stress factors also have an influence on forest condition and must therefore be taken into consideration. The objective of the Level II network was therefore: to contribute to a better understanding of the relationships between the condition of the forest ecosystems and anthropogenic factors (in particular air pollution) as well as natural stress factors through intensive monitoring on a number of selected permanent observation plots spread over Europe and to study the development of important forest ecosystems in Europe.
Data collection in the Level II/(Later FutMon) was modular in nature, in that it each assessment type was independent of the others. Included here are the daily meteorological data. Attribution statement: Please quote Forest Research as the source of the data in any subsequent papers/products.

鉴于对空气污染可能影响森林状况的普遍担忧，国际评估和监测空气污染对森林影响合作计划（ICP forests）于1985年在联合国欧洲经济委员会关于长距离跨境空气污染公约（CLRTAP）框架下成立。ICP Forests 被赋予监测空气污染对森林的影响并促进对因果关系的更深入理解的职责。在人类活动与自然压力的复杂交织中，空气污染持续被视为一个重要的压力因素。空气污染及其对森林生态系统的影响错综复杂，难以分离和量化。众多其他压力因素也对森林状况产生影响，因此必须予以综合考虑。二级网络的目的是因此：通过在欧洲多个选定的永久观测样地上的密集监测，增进对森林生态系统状况与人类活动因素（特别是空气污染）以及自然压力因素之间关系的理解，并研究欧洲重要森林生态系统的发展。在二级网络/后来的FutMon中，数据收集具有模块化特性，即每种评估类型相互独立。其中包括每日气象数据。归属声明：请在任何后续论文/产品中引用森林研究作为数据的来源。
