This dataset contains soil respiration data from the Climoor fieldsite in Clocaenog forest, north-east Wales. Measurements began in March 1999 at the field site, and were repeated in approximately bi-weekly intervals until June 2015 (although there are some larger gaps for technical or logistical reasons in this 14 year dataset). The data were collected using 3 different methods/machines over the years: static chambers, soil respiration chamber and Environmental Gas Monitor (EGM)-4 (from PP Systems), and soil respiration chamber and Automated Soil Gas Flux System Li8100 (from Licor Biosciences). The method used is detailed in the data and described further in the supporting documentation. Data was collected by CEH staff and PhD students trained in the use of the different methods / machines. Climoor is a climate change manipulation experiment that utilises automated roof technology to produce drought and warming experimental treatments that reflect climate change predictions for the next 20-30 years.
