Fortnightly soil respiration and related measurements from Climoor field site in Clocaenog Forest (2015-2016)

The data resource comprises of two datasets. The first dataset comprises of fortnightly measurements soil respiration, soil temperature, soil moisture and photosynthetic activity. The second data set comprises of fortnightly measurements of rainfall, throughfall and water table depth. Data were collected from the climate change field site Climoor that is located in Clocaenog forest, Northeast Wales during 2015 and 2016. The experimental field site consists of three untreated control plots, three plots where the plant canopy air is artificially warmed during night time hours and three plots where rainfall is excluded from the plots at least during the plants growing season (March to September,)
All measurements of this dataset have been carried out every fortnight if not indicated otherwise. Rainfall in millimetres (mm) was measured at the site using a ground-level rain gauge. Rain throughfall (in mm) was measured in each plot using a funnel-bottle construction to collect rain water in the plant canopy. Water table depth was measured for each plot using a measuring tape.
Soil respiration and related soil temperature and soil moisture were measured in three areas of each plot. Soil respiration was measured in pre-installed opaque soil collars (20 centimetre diameter) that were installed in 1999. An infra-red gas analyser (EGM-4) was used. Photosynthetic active radiation was measured above the canopy while the soil respiration measurement was conducted. The measurements were carried out by different groups of CEH Bangor staff.
The Climoor field experiment intends to answer questions regarding the effects of warming and drought on ecosystem processes. Plot level soil respiration measurements are important to investigate soil carbon dynamics and changes in soil carbon cycling and storage under the imposed climatic treatments.
More detailed information about the field site, measurements and related datasets can be found in the supporting documentation. Soil respiration data for 1999-2015 are published and can be requested using the NERC Environmental Information Data Centre and the DOI: 10.5285/4ed6f721-b23b-454e-b185-02ba54d551f0.

Provenance & quality

Rainfall was collected using a ground-level rain gauge at the site that was emptied fortnightly. Volumes were recorded in millilitres (mL) and converted to millimetres (mm).

Throughfall was measured in each plot using a funnel-bottle construction. Volumes were recorded in mL and were converted to mm.

Water table depths was measured in pre-installed tubes using a measuring tape. The distance from the water surface to the soil surface was measured and subsequently converted to water table depth in centimetres..

Soil respiration was measured in pre-installed soil collars in three location in each plot using an infra-red gas analyser. The soil respiration measurement took 120 seconds and was recorded in grammes of Carbon dioxide per square metre per hour (g CO2-C m-2 hr-1). Values were then converted to mg CO2-C m-2 hr-1 and the three plot measurements were averaged to a plot average.

Soil temperature and soil moisture were measured alongside the soil respiration measurement close to the pre-installed soil respiration collars. Soil temperature was measured using a thermometer, soil moisture was measured with a hand-held Theta-probe. Photosynthetic active radiation was measured above the canopy using a pyranometer.

All results were entered into Excel spreadsheets. Results from all the analyses were combined into one Excel spreadsheet. Data were then exported from this combined Excel spreadsheet as .csv files for ingestion into the EIDC.
