  • Airborne Southern Hemisphere Ozone Experiment and Measurements for Assessing the Effects of Stratospheric Aircraft (ASHOE/MAESA) was a combined experiment which was conducted in four phases between March and November 1994 at NASA Ames Research Center, California; Barbers Point, Hawaii; and Christchurch, New Zealand. This dataset contains ground-based spectrometer and monochromator measurements.

  • Universities Weather Research Network (UWERN) Urban Meteorology Programme (URBMET) was a Natural Environment Research Council (NERC) Urban Regeneration and the Environment (URGENT) Air project (GST/02/2231 - Duration: 1/01/1999 - 30/6/2002) led by Dr Stephen Belcher, University of Reading. This dataset contains wind tunnel model data from the University of Surrey.

  • Met Office high resolution (2 second) radiosonde data from the Dunkerswell station from November 1999. The data consist of vertical profiles of pressure, temperature, relative humidity, humidity mixing ratio, sonde position, wind speed and wind direction. Measurements are taken at 2 second intervals and the ascents extend to heights of approximately 20-30 km.

  • The Network for the Detection of Atmospheric Composition Change (NDACC), formerly known as the Network for the Detection of Stratospheric Change (NDSC), is a set of high quality, remote-sounding research stations for observing and understanding the physical and chemical state of the stratosphere. These stations, where ozone and key ozone-related parameters are measured, are complemented by both secondary stations and satellite measurements. Following five years of planning, instrument design and implementation, the NDACC began network operations in January 1991. The dataset contains high quality measurements of a wide range of stratospheric chemical species and parameters derived from instruments operated at a number of ground stations around the world.

  • The SMMR and SSM/I Pathfinder brightness temperatures provide scientists with more than 20 years of consistently processed, passive microwave data for use in climatological and earth science research. Each file represents gridded data for a single sensor channel and polarization, derived from either ascending or descending orbits for one day, thereby allowing discrimination of diurnal changes in earth surface processes. Each data sets consists of three series: the Northern and Southern Hemispheres and a global projection. Grids represent spatially interpolated data. The interpolation techniques maximize the radiometric integrity of original brightness temperature values, maintain high spatial and temporal precision, and involve no averaging of original swath data. SMMR coverage began October 1978 and continued through July 1987. Grid resolution is 25 km for all channels. SSM/I coverage began August 1987 and continues through the present. Processing is ongoing with current data available within three to six months of sensor data acquisition. Resolution is 25 km for all channels and 12.5 km for the 85 GHz channels. A sample data set comprising selected SSM/I EASE-Grid brightness temperature data and time files for all three projections from September 8 (day 251), 1997 is included on this CD-ROM.

  • The Meteosat Second Generation (MSG) satellites, operated by EUMETSAT (The European Organisation for the Exploitation of Meteorological Satellites), provide almost continuous imagery to meteorologists and researchers in Europe and around the world. These include visible, infra-red, water vapour, High Resolution Visible (HRV) images and derived cloud top height, cloud top temperature, fog, snow detection and volcanic ash products. These images are available for a range of geographical areas. This dataset contains infa-red images from MSG satellites over the tropics. Imagery available from March 2005 onwards at a frequency of 15 minutes (some are hourly) and are at least 24 hours old. The geographic extent for images within this datasets is available via the linked documentation 'MSG satellite imagery product geographic area details'. Each MSG imagery product area can be referenced from the third and fourth character of the image product name giving in the filename. E.g. for EEAO11 the corresponding geographic details can be found under the entry for area code 'AO' (i.e West Africa).

  • This dataset contains output data from a number of models from the UK Met Office Hadley Centre which was processed into text files at the Climate Research Unit at the University of East Anglia. The data extraction was intended for use by the Climate Impacts Community (and was funded by the UK Departement of Environment Food and Rural Affairs, Defra). Output from each model is stored in a separate directory in the BADC archive, and the majority of the data comes from experiments performed using the Hadley centre Coupled Model, Version 3 (HadCM3). Note that is dataset is kept for historical purposes only. More consistent and complete HadCM3 data is available from the main British Atmospheric Data Centre (BADC) HadCM3 archive.

  • The European Arctic Stratospheric Ozone Experiment is a European Commission (EC) measurement campaign undertaken in the Northern Hemisphere winter of 1991-92 to study ozone chemistry and dynamics. This dataset contains ozone and meteorology measurements.

  • The Airborne Arctic Stratospheric Expedition (AASE) which was based in Stavanger, Norway during January and February, 1989, was designed to study the production and loss mechanisms of ozone in the north polar stratospheric environment, and the effect on ozone distribution of the Arctic polar vortex and of the cold temperatures associated with the formation of Polar Stratospheric Clouds (PSC). This dataset contains ozone measurements taken on board the NIMBUS 7 Satellite.

  • Tropospheric ORganic CHemistry Experiment (TORCH) was a Natural Environment Research Council (NERC) Polluted Troposphere Research Programme project (Round 1 - NER/T/S/2002/00145. Duration 2002 - 2005) led by A. Lewis, University of York. TORCH 2 took place in April and May 2004 at Weybourne Atmospheric Observatory, on the north Norfolk coast. This dataset contains formaldehyde (HCHO) measurements.
