  • Skin Sea Surface Temperature data from the (A)ATSR Validation Campaign by SISTeR. The prime objective of the (A)ATSR mission is to return accurate measurements of the global sea surface temperature. To ensure the accuracy of the measurement, there have been joint efforts to validate the data. One of these efforts is the (A)ATSR Validation Campaign which involves the deployment of the Scanning Infrared Sea surface Temperature Radiometer (SISTeR). The SISTeR is a self-calibrating radiometer that measures the skin sea surface temperature. The SISTeR was mounted on MS Color Festival and MS Prinsesse Ragnhild to return skin sea surface temperature in the North Sea in 2006, and was on-board RMS Queen Mary 2 collecting data from the Atlantic Ocean, Indian Ocean and Western Pacific between 2010 and 2014. Data was collected continuously throughout the cruises unless severe weather conditions required the instrument to be protected, which results in the prevention of the data collection.

  • The Met Office NU-WAVE (Ice Nuclearisation in Wave Clouds) project aimed at studying ice crystal nucleation in orographic wave clouds. NU_WAVE was to study the nucleation of ice crystals in orographic wave clouds and its dependence on the physical and chemical properties of the input aerosol. The primary aim was to study heterogeneous nucleation processes acting in the temperature range 0 to -35C (but principally -15 to -35C). Where possible, however, the influence of homogeneous nucleation a temperatures colder than -35C were also studied. It was based on a 2-flight campaign (November 2004) on board the FAAM aircraft. Flights involved penetration of single wave clouds, trains of wave clouds and extensive sheets of cirrus formed by orographic effects.

  • The Contrail Forecast Verification Experiment (COVEX) was a Met Office experiment to validate the new contrail forecasting techniques based on engine parameters and environmental conditions. It was based on a one-flight experiment on board the Facility for Airborne Atmospheric Research (FAAM) aircraft, that took place in December 2004.

  • 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.

  • These data are held by the BADC for the Natural Environment Research Council (NERC) Molecular Spectroscopy Facility (MSF). MSF provides world-class scientific equipment and support for infrared (IR),visible, and ultraviolet (UV) spectroscopy. The MSF laboratories are used by many UK and international customers in a wide range of research and development programmes. The data are spectra of various atmospheric gases. These data are public. The data held covers the following areas: Water vapour line parameters Molecular oxygen absorption cross-sections Molecular oxygen/nitrogen absorption cross-sections Hydrofluorocarbon (HFC) infrared absorption cross-sections Perfluorocarbon (PFC) infrared absorption cross-sections Computer software

  • [THIS DATASET HAS BEEN WITHDRAWN]. This dataset includes manual measurements of water table depth at the Climoor fieldsite in the Clocaenog Forest, north-east Wales. Water table depth was collected via water permeable tubes installed through the soil profile down to bedrock. Measurements were taken, usually every two weeks, using a tape measure and head torch to assist in seeing the water level in the tube. Data are available from May 2009 to January 2014.

  • This dataset includes weekly data from monitoring of stream, rainfall and groundwater hydrochemistry in the Vyrnwy research catchment between 1994 and 2001. Data for over 50 chemical determinands are presented alongside data for some in-situ measurements such as water temperature. Full descriptions of the analytical methods used for each determinand is included. Intensive and long-term monitoring within the catchments underpins a wealth of hydrological and hydro-chemical research; other linked datasets include river flow, meteorology and a variety of detailed spatial datasets representing the topography, soils and rivers of the catchments. Monitoring is funded by the Centre for Ecology & Hydrology. Full details about this dataset can be found at https://doi.org/10.5285/68f4a12f-740d-4705-9c27-6a7fb7127046

  • Data collected during field experiments to investigate the effect of wildfires on greenhouse gas emissions across forests of differing ages in Sweden. Data comprise greenhouse gas measurements, soil horizon depth, bulk density, loss on ignition, pH, soil phosphorus, carbon and nitrogen, plant species cover, air temperature, soil temperature, soil moisture and surface leaf moisture. Greenhouse gas measurements were taken in the field. Soil cores were collected, then processed and analysed in the laboratory. Plant species cover was by visual estimate and final plant biomass was collected, dried, and weighed. Weather stations were used to collect temperature and moisture data. Data were collected from six Swedish boreal forest sites forming a chronosequence ranging in age from approximately 45 to 365 years since last wildfire. This part of the project used soil and plant property data, climatic data, and age since wildfire to investigate controls on forest floor greenhouse gas fluxes. The project ran from 2012 to 2015.

  • The dataset comprises counts of ten waterfowl species collected from Loch Leven from 1968-2007 by staff at Scottish Natural Heritage (SNH) and its predecessor bodies (Nature Conservancy), as part of their long-term monitoring programme of the lake. Counts are for the whole loch and represent an annual peak count based on the monthly counts recorded from September (of the year indicated) through to March (of the following year).

  • [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.
