Soil respiration data from Climoor fieldsite in Clocaenog Forest

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 Oct 2013 (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 EGM-4 (from PP Systems), and soil respiration chamber and Li8100 (from Licor Biosciences). The method used is detailed in the data and described further in the supporting documentation.

Three soil collars were installed per plot (5-10cm into the soil) in the plots in 1999. Any above-ground plan growth within the collars was removed on a regular basis. A soil respiration chamber connected to an EGM-4 from PP Systems was used prior to 2008, here data were downloaded from the EGM, and converted from the units provided (gCO2 m-2 hr-1) into mg CO2-C m-2 hr-1. From 2008, a survey soil respiration chamber and Li-8100 (Licor biosciences) were used. Data was downloaded from the Li-8100 into a raw data file. Within the raw data file linearity of the measurement was checked visually using the li-8100 software and the checked data was then saved under a separate file name. Following this, data was converted from the units provided (umol/m2/s) to mg CO2-C m-2 hr-1. For all time periods, measrements from the 3 soil collars in each plot were meaned to give an experimental plot average.
