  • The Total Ozone Mapping Spectrometer (TOMS) is an instrument built and operated by the National Aeronautics and Space Administration (NASA). The instrument uses backscattered ultraviolet radiance to infer total column ozone measurements. The data consists of daily gridded averages of total ozone covering the entire globe. The original Nimbus-7 TOMS operated from November 1978 until May 1993. Meteor-3 TOMS was launched in August 1991 and operated until December 1994. These CDs contain the total ozone and UV radiance data.

  • The Total Ozone Mapping Spectrometer (TOMS) is an instrument built and operated by the National Aeronautics and Space Administration (NASA). The instrument uses backscattered ultraviolet radiance to infer total column ozone measurements. The data consists of daily gridded averages of total ozone covering the entire globe. The original Nimbus-7 TOMS operated from November 1978 until May 1993. Meteor-3 TOMS was launched in August 1991 and operated until December 1994. After a gap of one and a half years, two new TOMS instruments began operation in 1996: Earth-Probe TOMS was launched on 2nd July 1996 and started to produce data on 25th July. ADEOS TOMS was launched on 17th August 1996 and started producing data on 11th September. The satellites were originally placed in different orbits, giving complete global coverage with the ADEOS data, while Earth-Probe had complete coverage at the poles with an increased ability to measure UV-absorbing aerosols in the troposphere. ADEOS failed in June 1997 and Earth-Probe was subsequently placed in a higher orbit to give global coverage. On Saturday, december 2, 2006, contact with Earth Probe was lost. There has been no communication with the spacecraft since. The spacecraft is intact and Earth-oriented which mean that it is still operational and maintaining attitude. On Wednesday December 6, the spacecraft was commanded to go to SAFE mode, in which it points at the sun, which will maintain power indefinitely. The spacecraft is now sun-pointing, indicating that the receiver and processor are working. Earth Probe has been operating on its backup transmitter since 1998 when the primary failed. The operations team tried to switching to the zenith antenna in hopes that the problem was the nadir antenna, but still no signal was received. This likely means that the transmitter has failed. At this point the probability of recovering looks poor but the Earth Probe team is still trying. Before contact was lost with Earth Probe, there were calibration problems with EP TOMS and so in the view of the good performance of the Ozone Monitoring Instrument (OMI) on the AURA spacecraft, OMI data of ozone are now available for the entire OMI mission beginning with August 17, 2004 through the most recent data. In addition to ozone data, OMI data for aerosol and reflectivity are available from August 17, 2004; images are available from here.

  • The International Satellite Land Surface Climatology Project was established in 1983 under the United Nation's Environmental Programme to promote the use of satellite data for the global land surface data sets needed for climate studies. This CD-ROM set contains the Initiative I data collection. The collection four areas : land cover, hydro-meteorology, radiation, and soils, spanning the 24 month period 1987-1988. All but one are mapped to a common spatial resolution and grid (1 degree x 1 degree). Temporal resolution for most datasets is monthly; however, a few are at a finer resolution (e.g., 6-hourly). The data within the four areas are organized into five groups within this collection: vegetation, Hydrology and Soils, Snow, Ice and Oceans, Radiation and Clouds, and Near-Surface Meteorology. This dataset collection is public. While ISLSCP Inititative I covers 2 years (1987 and 1988), ISLSCP Inititative II spans a 10-year period for 1986 to 1995.

  • BIRPS (the British Institutions Reflection Profiling Syndicate) acquired almost 650 km of offshore seismic data and 300 km of onshore seismic data over the Chicxulub impact crater. The data were recorded to 18 s two-way time.

  • An index to the manuscript notebook collection was set up in the 1990's. The notebooks themselves contain detailed information gathered by BGS geologists (or other recognised geologists) from various sources as part of the mapping of Great Britain since the 1840s. Examples include observations linked directly to field slips, borehole logs, sections and drawings. All the notebooks held by National Geological Records Centre (NGRC) are indexed but other notebooks held in the Library may not be included. The index is to the notebooks and is not a detailed index of the information in the notebook. Detailed information from coalfield areas is held in the Happs Hall Index. For the basic field mapping work notebooks have now been replaced by field record sheets.

  • This dataset of paper records holds details of analysis of all the sample batches (from both internal and external customers) analysed by the Analytical Geochemistry Laboratory of the BGS since June 1996. It was installed to underpin the UKAS (United Kingdom Accreditation Service) accreditation of the geochemistry laboratories at Keyworth, which was awarded in August 1999. There is a file for each batch of samples submitted for analysis. The file documents the progress of the samples through the laboratories, including sample registration, sample processing, raw data from analytical instruments and the data reported to the client. The records are archived to provide supporting evidence for any query regarding geochemical data provided by the laboratories.

  • Index data from field note record sheets. These records are produced by BGS geologists as part of the geological mapping process and are written descriptions of localities, or sections, or records of measurements taken in the field. Most are linked to a specific field map. The index was setup in 1999 and covers the whole of Great Britain.

  • Data from the Total Ozone Mapping Spectrometer (TOMS), which used backscattered ultraviolet radiance to infer total column ozone measurements (gridded daily for the entire globe). This CD-ROM contains one file for each day from November 1, 1978 to March 6, 1993 (with a few missing days). Each file contains data representing the relative daily areal exposures of ultraviolet (UV) radiation effective in causing skin irritation, computed at each 1 degree latitude by 1.25 degree longitude pixel, between latitudes 65S and 65N. These data were derived from measurements made by NASA's Total Ozone Mapping Spectrometer (TOMS), which was flown aboard the Nimbus-7 satellite.

  • Data from the Total Ozone Mapping Spectrometer (TOMS), which used backscattered ultraviolet radiance to infer total column ozone measurements (gridded daily for the entire globe). This 2 CD-ROM set contains the latest version (version 7) of reflectivity data from the TOMS (Total Ozone Mapping Spectrometer) instrument onboard the Nimbus 7 spacecraft. Data covering the entire Nimbus 7 TOMS lifetime, November 1, 1978 through May 6, 1993, are given as daily files of gridded data, as zonal means, and as monthly averages. A similar CD-ROM set (OPT_004A and OPT_004B) containing TOMS total ozone values is also currently available. A CD-ROM of version 7 data from the Meteor 3 TOMS instrument (August 1991 - December 1994) will be produced soon.
