  • Light Detection and Ranging (LiDAR) data was collected by The Geoinformation Group using LiDAR-equipped survey aircraft for the main urban conurbations of England and Wales (including London, Manchester, Birmingham, Liverpool, Newcastle, Edinburgh and Glasgow) as part of the Cities Revealed project, and made available through the Landmap service. The GeoInformation Group (TGG) has processed the data so that they are available as Digital Terrain Models (ground surface only) and Digital Surface/Elevation Models (the ground and all features on it), both geographic databases with height and surface measurement information in the form of regular grids with intervals of 1 or 2 m. In addition, some First Pass and Last Pass data are available. The First Pass data provides height values for the top of the canopy (i.e. buildings, trees etc.) while the Last Pulse data provides height values for the bottom of the canopy and provides information about the shape of the terrain. The data are available in img format. The Joint Information Systems Committee (JISC) funded Landmap service which ran from 2001 to July 2014 collected and hosted a large amount of earth observation data for the majority of the UK, part of which was elevation data. After removal of JISC funding in 2013, the Landmap service is no longer operational, with the data now held at the NEODC.

  • LiDAR data was collected by the UK Environment Agency on 17th June 2006 as part of the Network for Calibration and Validation of EO data (NCAVEO) 2006 Field Campaign. The data was collected from a Cessna 404 aircraft carrying an Optech 3100 LiDAR. The sensor was integrated with the on-board navigation system to provide accurate geometric correction through post-processing. The LiDAR was operated at 33 kHz to give a nominal pulse spacing around 1-2 m, and intensity plus first and last pulse returns were recorded. For further information please see the LiDAR survey report in linked documentation and the dataset's metadata document.

  • The Cloud and Water Vapour Experiment (CWAVE) was a measurement campaign at the CCLRC-Chilbolton Observatory; it was supporting associated with two EC FP5 projects, CLOUDMAP2 and CLOUDNET. A wide range of satellite and ground based instruments measured a variety of atmospheric properties ranging from cloud parameters to water vapour. In addition, the measurements coincided with the results from a reduced resolution Unified Model (UM) run by the Met Office.

  • This dataset contains ozone and backscatter measurements from the CNRS UV LIDAR onboard the UPMC-SA Mystere aircraft flown during the European eXport of Precursors and Ozone by long-Range Transport (EXPORT) project . The primary objective of EXPORT was to characterise and quantify the photochemical air pollution both forming over Europe and being exported eastwards from Europe. The data held at BADC were collected during a co-ordinated 3 aircraft flying campaign in August 2000 based at Oberpfaffenhofen in Southern Germany. Measurements were made of many photochemical parameters including ozone, its precursors, other oxidants and both gas phase and particulate tracers in the air over Europe and that being transported eastwards out of Europe.

  • The EMERALD projects were airborne measurement campaigns designed to study dynamical, microphysical and infra-red radiative properties of cirrus clouds, using both in-situ and remote measurement techniques. The dataset contains static air temperature, static air pressure, relative humidity, water vapour mixing ratio, and ozone mixing ratio. These data are part of the NERC Clouds, Water Vapour and Climate (CWVC) programme.

  • An atmospheric water vapour profile was recorded using a UV Raman LiDAR located at Chilbolton Facility for Atmospheric and Radio Research (CFARR), during the Network for Calibration and Validation of EO data (NCAVEO) 2006 Experiment. The profile was recorded on 16th June 2006, one day before the ‘golden day’. The ground-based Raman LiDAR system at the CFARR transmits a high power Nd:YAG pulse laser beam vertically into the atmosphere at 355 nm wavelength. The LiDAR measures both elastic backscattering and water vapour profiles in the troposphere. Inelastic scattering of the laser radiation by molecules in the atmosphere, termed Raman scattering, is used to determine the atmospheric water vapour and temperature profiles. This dataset contains data for the raw (20s/7.5m) and processed (5min/22.5m) data in separate files. For further information on the parameters used during the data collection and the data's file format please see the dataset's metadata document in linked documentation.

  • 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.
