  • The CRYOspheric STudies of Atmospheric Trends in stratospherically and radiatively important gases (CRYOSTAT) will undertake the first combined measurements of virtually all significant Greenhouse gases (GHGs)(other than water vapour), ozone-depleting substances (ODSs), and related trace gases in contiguous firn and ice profiles, spanning as much as 200 years, from both the northern and southern polar ice caps. The dataset contains concentrations of isotopes (CH4, N20, CO, CO2, N20, SF6, CH3Br, halocarbons, and hydrocarbons) in firn, N2O concentrations in ice, ice core density, firn diffusivity, and weather measurements. CRYOSTAT is an evolution of the FIRETRACC/100 project, the data from which is also held at BADC.

  • The dataset contains dissolved greenhouse gas and water chemistry data collected across 12 axial surveys of the Tay estuary, Scotland, starting in April 2009 and ending in July 2011. Ten fixed sampling points on the estuary were surveyed on each boat based campaign. Data were obtained either via direct, field-based measurements, or via subsequent sample processing and analysis in laboratories at UKCEH Edinburgh.

  • An international long-term collaboration to study the climatic and environmental feedback mechanisms involved in the African monsoon, and in some of its consequences on society and human health. The programme, which started in 2004, has developed a network of ground-based observation stations over Sub-Saharan West Africa to measure heat flux and, for some stations, CO2 and H2O vapour fluxes. Files also include concomitant meteorological measurements (wind, temperature, pressure, humidity, rainfall) and soil physics parameters (soil temperature and moisture). The UK branch of AMMA makes use of several instruments provided by the UK Universities Facility for Atmospheric Measurement (UFAM) which are centred on the Niamey meso-site. The Facility for Airbourne Atmospheric Measurements (FAAM) aircraft was used during the July-August 2006 campaign.

  • The FLUXEX (Flux Experiment) project was an experiment to establish the fluxes of many ozone depleting gases (CFCs, HCFCs, halons) and greenhouse gases (HFCs, PFCs, SF6) from the UK. Its aim was to assess regional emission inventories of these gases to feed the UNEP/WMO Ozone Assessment and the UNFCCC. Attempts were also made to measure for the first time "new" ozone depleting gases, such as n-propyl bromide and hexachlorobutadiene, and to estimate UK emissions. To achieve this purpose, the FAAM aircraft, fitted with air sampling bottles, was flown in the boundary layer upwind and downwind of the UK. A total of 9 flights took place between 30. March and 29. September 2005.

  • The data resource consists of half hourly time series of heat (latent and sensible) and trace gas (carbon dioxide and methane) fluxes obtained by eddy-covariance, gas concentrations and ancillary meteorological data (e.g. air temperature, relative humidity, pressure, photosynthetically active radiation, total incoming radiation, wind speed and direction). The data were collected at Guma Lagoon (18°57'53.01"S; 22°22'16.20"E), in the perennially flooded area of the Okavango Delta, Botswana, for the purpose of quantifying greenhouse gas fluxes over a Cyperus papyrus stand. The measurement period was 01/01/2018 to 31/12/2020. The instrumentation was installed the UK Centre for Ecology and Hydrology; monthly maintenance and data collection visits were effected by the Okavango Research Institute, University of Botswana. The research was funded through NERC grant reference NE/N015746/2 - The Global Methane Budget.

  • The dataset contains aquatic carbon and dissolved greenhouse gas data collected from 6 headwater stream sampling sites within the UK’s largest tract of blanket bog, the Flow Country of N. Scotland. The streams drain from catchments under different peatland management regimes: natural non-drained peatland, drained peatland, and restored peatland (achieved via ditch blocking). Sites were sampled on an approximately fortnightly basis between September 2008 and August 2010. Data were obtained via collection of water and gas samples in situ, and concentrations were derived via subsequent sample processing and analysis.
