This dataset includes individual passive detector measurements of radon Rn-222 in the air of artificial burrows, Rn-222 measurements by instrumentation in soil gas of interstitial soil pores and burrow air, gamma analyses results for soil samples and, soil moisture and temperature data. Estimates of absorbed dose rates to wildlife from exposure to natural background radionuclides are required to put estimates of dose rates arising from regulated releases of radioactivity and proposed benchmarks into context. These data are from a study conducted at seven sites in northwest England (comprising broadleaved and coniferous woodlands, scrubland and pastures). Passive track etch detectors were used to measure the Rn-222 concentrations in artificial burrows over a period of approximately one year (July 2009 to June 2010). Instrumented measurements of burrow air and soil pore gas were also conducted in October 2009. The data result from a study funded by NERC-CEH and the England & Wales Environment Agency.

The 20th Century Reanalysis (Version 2) Dataset was produced by the National Oceanic and Atmospheric Administration (NOAA) and University of Colorado's Cooperative Institute for Research in Environmental Sciences (CIRES), members of the international Twentieth Century Reanalysis (20CR) project. This dataset collection contains twentieth century global climate reanalysis data, including output from each 56 members of the ensemble runs, their means, spreads and input observational data. The reanalysis was performed in various runs, each producing a 5 year period of output data. The data were produced through international cooperation under the auspices of the international Atmospheric Circulation Reconstructions over the Earth (ACRE) initiative, and working groups of the Global Climate Observing System (GCOS) and the World Climate Research Program (WCRP). The 20CR project produced comprehensive global atmospheric circulation data spanning from late 19th century to the early 21st century, having only assimilated surface synoptic pressure observations and using observed monthly sea-surface temperature and sea-ice distributions from the HadISST dataset, courtesy of the Met Office Hadley Centre, as boundary conditions. Analyses every 6 hours on a 2 degree grid were produced to give the most likely state of the atmosphere based on a 56 ensemble member runs. Means, spreads and all ensemble members for each time step are available in the dataset archived at the BADC. The current 20CR output produced spans from 1871 to present with the BADC copy being updated when possible.

This data consist of measurements on soil microbial enzyme activity of six hydrolytic enzymes and related soil measurements from the experimental field sites at Clocaenog forest and Peaknaze. Samples were collected in 2012 from plots subjected to experimental drought and warming as well as untreated control plots. Soil cores were taken for the topsoil 0 to10 centimetres. Enzymes were measured at the climate change field site Climoor that is located in Clocaenog forest, North East Wales and the Peaknaze field site located in the Peak District. The experimental field sites each consist 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). Six hydrolytic soil microbial enzymes and one oxidase were extracted from the topsoil to test the effect of these enzymes that are involved in carbon, nitrogen and phosphorus cycling, under the imposed long-term climate change treatments. The hydrolytic enzymes were assayed using 4-methylumbelliferone (MUF) or 7-amino-4-methyl coumarin (AMC) linked-substrates, whereas the oxidase was extracted in pure water. All enzyme extracts were measured colorimetrically. The Clocaenog and Peaknaze field experiments intend to answer questions regarding the effects of warming and drought on ecosystem processes. Plot level microbial related measurements are important to investigate ecosystem carbon dynamics and changes in the soil carbon under the imposed climatic treatments. Measurements were undertaken by trained members of staff at the UK Centre for Ecology & Hydrology.

WCRP CMIP5: Met Office Hadley Centre (MOHC) HadGEM2-A model output collection.

Land surface and marine surface observations data from the Met Office station network and other world wide stations as stored in the Met Office MIDAS database. Data are available for the period 1853 to present. The dataset comprises daily and hourly weather measurements, hourly wind parameters, max and min air temperatures, soil temperatures, sunshine duration and radiation measurements and daily, hourly and sub-hourly rain measurements, some climatology data and marine observations (including sea surface temperature, swell and wave associated parameters). This dataset collection supersedes the Met Office Land Surface Stations Dataset collection (1900-2000), also archived at the BADC.

Future Flows Climate (FF-HadRM3-PPE) is an 11-member ensemble climate projection for Great Britain at a 1-km resolution spanning from 1950 to 2098. It was specifically developed for hydrological application and contain daily time series of Available Precipitation, which is the precipiated water available to hydrological processes after delays due to snow and ice storage are accounted for; and monthly reference Potential Evapotranspiration calculated using the FAO56 method. Future Flows Climate is derived from the Hadley Centre's Regional climate projection ensemble HadRM3-PPE based on 11 different variants of the regional climate model run under the SRES A1B emission scenario. HadRM3-PPE is underpinning the UKCP09 products. Bias correction and spatial downscaling were applied to the total precpitation and air temperature variables before Future Flows Climate APr and PE were generated. The development of Future Flows Climate was made during the partnership project 'Future Flows and Groundwater Levels' funded by the Environment Agency for England and Wales, Defra, UK Water Research Industry, NERC (Centre for Ecology & Hydrology and British Geological Survey) and Wallingford HydroSolutions.
