This data set details the range of treatments applied to experimental plots at a field site at Sourhope, Scotland, between 1999 and 2004. The data can be used in conjunction with other experimental data sets from the NERC Soil Biodiversity Thematic Programme site as an explanatory variable. The NERC Soil Biodiversity Thematic Programme was established in 1999 and was centred upon the intensive study of a large field experiment located at the Macaulay Land Use Research Institute (now the James Hutton Institute) farm at Sourhope in the Scottish Borders (Grid reference: NT8545019630). During the experiment, the site was monitored to assess changes in above-ground biomass production (productivity), species composition and relative abundance (diversity).

Study of intercontinental transport of air pollutants by means of coordinated flights over the East coast of North America, the Azores and the West coast of Europe. ITOP was a component of the International Consortium for Atmospheric Research on Transport and Transformation (ICARTT), an international initiative which coordinates the efforts of various American and European groups who have developed plans for field campaigns in the summer of 2004, with the aim of improving our understanding of the factors determining air quality over the two continents and over remote regions of the North Atlantic. The British contribution to ITOP, referred to as ITOP-UK, was funded by the Natural Environment Research Council (NERC) through the Upper Troposphere Lower Stratosphere (UTLS)-Ozone Directed Research Programme. The ITOP-UK dataset includes trajectories and other forecast products calculated by John Methven (University of Reading), based on European Centre for Medium-Range Weather Forecasts (ECMWF) forecast wind fields, to support ICARTT flight planning, near-real-time chemical analyses produced by the University of Cambridge, and data collected aboard the FAAM Bae-146 aircraft in July and August 2004.

The aim of HITRAN (high-resolution transmission molecular absorption database) was to characterise the amount and wavelength-dependence of absorption by water vapour and other atmospheric species. It was part of the Natural Environment Research Council (NERC) funded Clouds, Water Vapour and Climate (CWVC) program. The dataset contains spectral line parameters derived from laboratory measurements on pure water vapour, and mixtures of water vapour and air. The measurements were made at STFC Rutherford Appleton Laboratory Molecular Spectroscopy Facility, and the line fitting was carried out by the Department of Meteorology at the University of Reading. The spectral line parameters are displayed in HITRAN format. Water vapour lines were fitted to the laboratory data in the spectral range 5037 to 5585 cm-1. These data are public.

The Aerosol Direct Radiative Impact Experiment (ADRIEX) was a joint UK Met Office/Natural Environment Research Council (NERC)/UK Royal Society/University of Oslo project aiming at improving our understanding of the radiative effects of anthropogenic aerosol and gases (ozone and methane) in the troposphere. The project is based on an airborne field campaign (August-September 2004) using the Facility for Airborne Atmospheric Measurements (FAAM) aircraft. The flights were based in Treviso (Italy) and covered areas over Northern Italy, the Adriatic Sea and between Northern Italy and the West coast of the Black Sea. The ADRIEX archive includes forecast trajectories and other products to support ADRIEX flight plans (computed using European Centre for Medium-Range Weather Forecasts (ECMWF) wind fields) and Aerosol Concentrations collected aboard the FAAM Bae-146 aircraft in August and September 2004.

TOPography EXperiment (TOPEX) for ocean circulation (otherwise known as Poseidon) was launched on August 10, 1992 and was a joint satellite mission between NASA, the U.S. space agency, and CNES, the French space agency, to map ocean surface topography. The first major oceanographic research vessel to sail into space, TOPEX/Poseidon helped revolutionise oceanography by proving the value of satellite ocean observations. This dataset collection contains monthly means on a 1x1 latitude/longitude grid for 12 years (1993-2004). The data contains the following parameters: wind speed, squared wind speed, cubed wind speed, wind speed * significant wave height, significant wave height, 1/sigma0(Ku) and gas transfer velocity. The dataset was produced by Fangohr, S. and D.K. Woolf of SOCS, as part of the NERC programme's Centre for observation of Air-Sea Interactions and FluXes (CASIX) and National Centre for Earth Observation (NCEO).

The FAAM is a large atmospheric research BAE-146 aircraft, run jointly by the NERC and the UK Met Office. It has been in operation since March 2004 and is at the scientists' disposal through a scheme of project selection. Data collected by this aircraft is stored in the FAAM data archive and includes "core" data, provided by the FAAM as a support to all flight campaigns, and "non-core" data, the nature of which depends on the scientific goal of the campaign. FAAM instruments provide four types of data: - parameters required for aircraft navigation; - meteorology; - cloud physics; - chemical composition. The data are accompanied by extensive metadata, including flight logs. The FAAM apparatus includes a number of core instruments permanently onboard and operated by FAAM staff members, and a variety of other instruments, grouped into chemistry kit and cloud physics kit, that can be fitted onto the aircraft on demand. FAAM is also a member of the EUropean Facility for Airborne Research (EUFAR) fleet of research aircraft. Apart from some exceptions, access to processed core data is public but requires an online application (application is granted automatically after agreement with the FAAM Conditions of Use). Access to non-core data is ruled by the relevant protocols in force for each project.

The European AQUA Thermodynamic Experiment (EAQUATE) was a study of the atmosphere, the land surface and the ocean surface by means of a range of airborne high resolution souders, in conjunction with observations from the Aqua and Aura satellites. The EAQUATE archive held at the British Atmospheric Data Centre (BADC) includes data collected aboard the Facility for Airborne Atmospheric Measurements (FAAM) Bae 146 aircraft based at Cranfield, UK, during four flights in September 2004.

The dataset comprises maps and aerial photographs of the Falkland Islands. The maps are printers films and final paper printed originals of Falkland Islands OS maps, compiled for the Falkland Islands Government and the Foreign and Commonwealth Office by the Overseas Directorate of the Ordnance Survey. They were discarded by the Ordnance Survey around 2004, and offered to BGS for storage on behalf of the Falkland Islands Government. The Falkland Islands Government retains copyright interest in the maps. There are no access or usage constraints for BGS staff for BGS purposes. The aerial photographs and associated paper overlays represent copies of field slips of geological maps that were compiled by BGS under contract to the Falkland Islands Government. Copyright remains with the Falkland Islands Government , but there are no access or usage constraints for BGS staff for BGS purposes. Access to both datasets are restricted to BGS staff.

The Convective Storm Initiation Project (CSIP) aimed to further the understanding of the mechanisms responsible for the initiation of precipitating convection in the maritime environment of southern England; i.e. to understand why convective clouds form and develop into precipitating clouds in a particular location. Data have been collected from the 13th June 2005 to the 25th August 2005 by the Ultra-violet Raman lidar at Chilbolton Observatory, Hampshire. The dataset contains measurements of attenuated backscatter coefficients of aerosols within the atmosphere, and humidity mixing ratios. Plots of the attenuated backscatter coefficient, and of the humidity mixing ratios, at different heights are also available.

The University of Wales, Aberystwyth, 1290mhz mobile wind profiler - now referred to as the University of Manchester mobile wind profiler, was operated at the Weybourne Atmospheric Observatory during the 2nd field campaign of the Tropospheric ORganic CHemistry Experiment (TORCH) Project. The TORCH project was part of the Natural Environmental Research Council's (NERC) Polluted Troposphere research programme. The field campaign ran from 22nd April to 28th May 2004, during which period the mobile wind profiler obtained vertical profiles of the horizontal and vertical wind components. For each signal beam profiles of the signal to noise (SNR) ratio and spectral widths were also taken. The data consist of files in the netCDF binary format and plots in PNG format. Data are available to all BADC registered users under the Government Open Data licence.
