Data from the Climoor climate change experimental fieldsite in Clocaenog forest, UK

Datasets within this series include site meteorological data, plot level micro-meteorological data, rainfall chemistry and volume, soil respiration, plant survey data (includes biomass and species diversity/abundance), spring emergence data for dominant plant species, annual vegetative growth and flowering, photosynthesis, vegetation chemistry of both green and senesced material, root biomass, litterfall, soil water chemistry, plant herbivory and fungal infection. The Climoor field site is a climate change experiment which investigates the possible impact of increase temperatures and repeated summer drought on an Atlantic upland moorland. The experiment uses automatic roof technology to warm experimental plots by 0.5 - 1 degC and reproduces drought conditions in other experimental plots(July to September annually). We have measured a range of key community characteristics and processes (ranging from plant diversity to rates of soil respiration) since the experiment began in 1998. In 2014, the Climoor experiment was the second longest running climate change experiment in the UK and data from the experiment has been used in several modelling exercises. The site was originally established under a EU consortium project - called CLIMOOR - where replica manipulation experiments were built in six European countries. As well as our site in North-East Wales (United Kingdom), there are identical sites in Denmark, the Netherlands, Sardinia (Italy) and Hungary. There was also a site in Catalonia (Spain). Detailed descriptions of the site (including both vegetation and soil) and treatments are included in the supporting information as well as the methods used, and it is vital that this is considered when re-using this data.
