The Coupled Ocean Atmosphere and European Climate (COAPEC) is a NERC thematic programme designed to examine the variability of the Earth's climate. The goal of COAPEC is to determine the impact on climate, especially European climate, of the coupling between the Atlantic Ocean and the atmosphere. The British Atmospheric Data Centre (BADC) is the primary distribution data centre for COAPEC. This dataset contains output from the 500 year HadCM3 control integration performed with UM version 4.5 on a Linux Beowulf Cluster for COAPEC.

Stratospheric Aerosol and Gas Experiment III (SAGE III) was an instrument on board a Meteor-3M spacecraft, launched on December 10, 2001. Routine measurement operations began in March 2002 until the SAGE III mission was terminated in March 2006. The specific measurement objectives of SAGE III provide 1 km vertical resolution profiles of: aerosols and clouds at seven wavelengths from the mid-troposphere into the stratosphere and where appropriate, the mesosphere; O3 from the mid-troposphere to 85 km; H2O from the planetary boundary layer to 50 km; NO2 from the tropopause to 45 km; NO3 from 20 to 55 km; OClO from 15 to 25 km; and, O2 from the mid-troposphere to 70 km. This dataset contains level 1B version 3 transmission profiles. The Level 1B Transmission product contains the SAGE III atmospheric slant path transmission profiles at 87 spectral channels. The profiles are skewed vertically and extend from sea level to an altitude of 100 km in 0.5 km intervals. The standard deviation of the binned transmission data is also provided for each reported altitude and channel. These data have been geolocated and normalized against exoatmospheric solar measurements to produce slant path transmission profiles.

The University of Wales, Aberystwyth 1290 MHz mobile wind profiler, deployed as part of a suite of instrument from Universities' Facility for Atmospheric Measurements (UFAM), was sited at Linkenholt, Hampshire, UK, for the duration of the Convective Storm Initiation Project (CSIP)'s main field campaign. The instrument was operated throughout the campaign, producing vertical profiles of wind speed and direction (horizontal and vertical components), signal to noise ratio and spectral width measurements from 2nd June to 1st September 2005. This instrument is now referred to as the University of Manchester mobile wind profiler (man-radar-1290mhz).

The Global Ozone Monitoring Experiment (GOME) was an instrument aboard ERS-2. The main scientific objective of the GOME mission is to measure the global distribution of ozone and several trace gases which play an important role in the ozone chemistry of the Earth's stratosphere and troposphere, for example, NO2, BrO, OClO, and SO2. This dataset contains version 2.0 ozone profiles derived by the Remote Sensing Group (RSG) at the STFC Rutherford Appleton Laboratory, Oxfordshire, UK, as part of the National Centre for Earth Observation (NCEO). These were derived from radiances measured by the GOME on-board ERS-2. The collection also includes total column ozone, column BrO, and column NO2 as well as cloud heights derived from the Along Track Scanning Radiometer (ATSR), which are included to aid interpretation of the ozone profiles.

The Meteorological Research Flight (MRF) was a Met Office facility, which flew a well-instrumented C-130 Hercules aircraft for atmospheric research purposes. This dataset contains airborne atmospheric and chemistry measurements taken on board the Met Office C-130 Hercules aircraft flight A400 for research purposes.

The University of Aberystwyth mobile ozone lidar data contain measurements of ozone mixing ratios and aerosol information. The data were collected at Chilbolton observatory, Hampshire on the 7th and the 8th of June 2005. The data collected on the 7th of June 2005 are of ozone mixing ratios only. The data collected on the 8th of June 2005 are of ozone mixing ratios, aerosol backscatter, and boundary layer height information.

The Meteorological Research Flight (MRF) was a Met Office facility, which flew a well-instrumented C-130 Hercules aircraft for atmospheric research purposes. This dataset contains airborne atmospheric and chemistry measurements taken on board the Met Office C-130 Hercules aircraft flight A298 for research purposes.

Data were collected by stations at Cyprus and Gibraltar from 1900 until 2000. These data are the Met Office's 'old' Land Surface Observation data and have been superseded by the MIDAS dataset collection. This dataset remains for historic purposes only. The data contain measurements of hourly and daily meteorological values, such as rainfall, sunshine duration, temperature, and wind speed. The MIDAS dataset supersedes this dataset and new users should apply for access to that by following the on-screen instructions. If necessary, you will be able to access this historic dataset once you have been granted access to the MIDAS data. The dataset contains the measurements of the following parameters: Sunshine duration Snow depth Visibility Wind speed and wind direction Temperature Cloud type Past and present weather

The UK soil temperature data describes daily and hourly values of soil temperatures at depths of 5, 10, 20, 30, 50, and 100 centimetres. The measurements are recorded by observation stations across the UK and transmitted within NCM or DLY3208 messages. The data spans from 1900 to present.

The global weather observation data contain meteorological values observed at 3-hrly intervals by non-UK stations, as reported in SYNOP and METAR codes. The messages contain measurements of the concrete state, wind speed and direction, cloud type and amount, visibility, temperature, sunshine duration, precipitation amount, and present and past weather. The data span from 1974 to present.
