  • [THIS DATASET HAS BEEN WITHDRAWN]. This dataset includes rainfall data from a ground level rain gauge as well as from basic storage rain gauges within the experimental plots in the Climoor field site in the Clocaenog Forest. Data includes volume of rainfall at both site and plot level, and rainfall chemistry (site level) from 1999-2012. Determinands include: Sodium (Na), Potassium (K), Calcium (Ca), Magnesium (Mg), Aluminium (Al), PO4-P, Chlorine (Cl), Phosphorus (P), Nitogen (N), Ammonium Nitrogen (NH4-N), Nitrate Nitrogen (NO3-N), Sulphate (SO4), dissolved organic Carbon (DOC) and pH for 1999-2002; and NH4-N, NO3-N, SO4, DOC and pH for 2002-2012.

  • The "ISOMAP UK" project was a combined data-modelling investigation of water isotopes and their interpretation during rapid climate change events project was a Natural Environment Research Council (NERC) RAPID Climate Change Research Programme project (Round 1 - NER/T/S/2002/00460 - Duration 1 May 2003 - 30 Apr 2008) led by Prof J.A. Holmes of the University College London, with co-investigators at the University of Southampton, University of Liverpool, University of Manchester, University of Bristol and the NERC British Antarctic Survey. This dataset contains comparison of high-resolution isotope records from terrestrial archives in NW Europe with model simulations of isotopes in precipitation. This is a control 9K simulation, and a freshwater hosing experiment. The freshwater hosing experiment had 5Sv of freshwater added to the North Atlantic for 1 year. The freshwater forcing was then removed and the model allowed to adjust. Rapid Climate Change (RAPID) was a £20 million, six-year (2001-2007) programme for the Natural Environment Research Council. The programme aimed to improve the ability to quantify the probability and magnitude of future rapid change in climate, with a main (but not exclusive) focus on the role of the Atlantic Ocean's Thermohaline Circulation.

  • Rapid Climate Change (RAPID) was a £20 million, six-year (2001-2007) programme for the Natural Environment Research Council. The programme aimed to improve the ability to quantify the probability and magnitude of future rapid change in climate, with a main (but not exclusive) focus on the role of the Atlantic Ocean's Thermohaline Circulation. This dataset collection contains comparison of high-resolution isotope records from terrestrial archives in NW Europe with model simulations of isotopes in precipitation. The aims of the proposal were to compare high-resolution isotope records from terrestrial archives in NW Europe with model simulations of isotopes in precipitation in order to investigate the role of different forcing factors in rapid climate change during the late glacial and Holocene and to undertake model validation. The proposal constitutes a UK contribution to the PAGES ISOMAP initiative. A water isotope model was developed for the UK Hadley centre model HadCM3. Comparisons have been made between simulations of the isotopic composition of precipitation during periods of rapid climatic change and reconstructions from well-dated and well-calibrated palaeo-archives (lake sediments, peat and speleothem) generated in this study and obtained from the literature, in order to investigate the causes and nature of abrupt climatic events.

  • [THIS DATASET HAS BEEN WITHDRAWN]. This dataset includes a range of determinands present in soil water in the experimental plot at the Climoor field site in the Clocaenog Forest, in north-east Wales. Soil water was collected at two depths in the soil profile - approximately 5cm and 20cm. At the bottom of the rooting zone (approximately 5cm depth) zero tension lysimeters were used. At the deeper depth (approximately 20cm depth) ceramic cup suction samplers were used. Data were collected between October 1998 and March 2009 at two weekly intervals. Determinands include: pH, Ammonium nitrogen (NH4-N), Nitrate nitrogen (NO3-N), Sulphate (SO4-S), dissolved organic carbon, dissolved organic nitrogen, Calcium (Ca), Potassium (K), Magnesium (Mg), Sodium (Na), Phosphate phosphorus (PO4-P), Chloride (Cl), total dissolved phophorus and total dissolved nitrogen.

  • This dataset consists of monthly mean inshore surface water temperature (degrees C) data from Windermere, a lake in northern England. Data collection began in 1933, but data are presented here from 1946 onwards. The data were initially collected by the Freshwater Biological Association (FBA), then by CEH and its predecessor Institute of Freshwater Ecology (IFE) from 1989 to 2003, and subsequently again by FBA.

  • Future Flows Hydrology (FF-HydMod-PPE) is an 11-member ensemble projections of river flow and groundwater levels time series for 283 catchments and 24 boreholes in Great Britain. It is derived from Future Flows Climate, an 11-member 1-km bias-corrected and downscaled climate projection products based on the SRES A1B emission scenario. River Flows data are at a daily time step: Groundwater Levels data are at a monthly time step. Future Flows Hydrology span from 1951 to 2098. The development of Future Flows Hydrology 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.

  • Data comprise estimates of activity concentrations of naturally occurring radionuclides (40K, 238U and 232Th series radionuclides) in environmental media (soil and stream sediments and waters) and non-human biota (focusing on the ICRP Reference Animals and Plants). For soil, stream sediments and stream waters data were derived from total K, U and Th concentrations mainly from the ongoing geochemical survey of the United Kingdom (G-BASE), conducted by the British Geological Survey. The geochemical survey data are currently incomplete for England and Wales, but almost complete coverage was obtained for K in stream sediments by using the Wolfson Atlas data for southern England. For U and Th in sediments and K, U and Th in soils, more complete coverage was achieved by geological extrapolation (using relationships between soils/sediments and bedrock/superficial geology). For media and sediments, datasets are provided for both: (i) geometric mean concentrations from measured samples on a 5 x 5 km square basis where data are available; and (ii) extrapolated surfaces covering all of England and Wales. Data for non-human biota are from targeted sampling and analyses and data review. Full details about this dataset can be found at https://doi.org/10.5285/bb2d7874-7bf4-44de-aa43-348bd684a2fe

  • This dataset contains modelled outputs of the European river network modelled as 33,668 cells (5° longitude by 5° latitude). For each cell, modelled monthly flows were generated for an ensemble of tenscenarios for the 2050s and for the study baseline (naturalized flows for 1961 to 1990). Score classes are categorisation of flow alteration scenarios. Full details about this dataset can be found at https://doi.org/10.5285/d8ef71eb-3d22-4f98-af15-9d8e046ccb63

  • Data from observations made at the Cape Verde Atmospheric Observatory (CVAO) which exists to advance understanding of climatically significant interactions between the atmosphere and ocean and to provide a regional focal point and long-term data. The observatory is based on Calhau Island of São Vicente, Cape Verde at 16.848N, 24.871W, in the tropical Eastern North Atlantic Ocean, a region which is data poor but plays a key role in atmosphere-ocean interactions of climate-related and biogeochemical parameters including greenhouse gases. It is an open-ocean site that is representative of a region likely to be sensitive to future climate change, and is minimally influenced by local effects and intermittent continental pollution. The dataset contains long term measurements of CO mixing ratio made from 7.5m using a fast response vacuum ultraviolet fluorescence CO analyser (Aerolaser 5001) 2008-2015 and using a Picarro G2401 Analyser from 2015 onwards .

  • This dataset consists of total weekly catch data of mature Perch (Perca fluviatilis) from trapping at Green Tuft, Windermere, Cumbria, sampled between 1946 and 2012. Perch have been monitored in the north and south basins of Windermere by trapping with variations in sampling sites and efforts from 1943 to the present. The data were initially collected by the Freshwater Biological Association (FBA) but have been collected by the Centre for Ecology & Hydrology (CEH) and its predecessor Institute of Freshwater Ecology (IFE) since 1989.
