  • Measurements from a LI-COR LI-7500 open path gas analyser operating at infra-red wavelengths deployed at the Chilbolton Facility for Atmospheric and Radio Research site in Chilbolton, Hampshire. The instrument measures the absorption due to carbon dioxide at specific wavelengths along its 0.125m measurement path. Internally-stored calibration data are used to convert these absorption values to a mole concentration for each gas. Carbon dioxde and water vapour mole concentrations from this instrument are also provided with sonic anemomenter data at a 20Hz data acquisition rate for eddy covariance calculations in another CFARR dataset. Measurements are taken at 10s intervals and are archived at this temporal resolution. Data are in netCDF.

  • Data from Marine Conservation Zone (MCZ) surveys are archived in the MEDIN Data Archive Centre (DAC) for Geology and Geophysics at the British Geological Survey. This includes geology (Particle Size Analysis) data and multibeam backscatter data. Data are delivered via the BGS Offshore GeoIndex. Additional data are available on request enquiries@bgs.ac.uk. Other data types are archived with the other MEDIN DACs as appropriate (UKHO DAC for bathymetry data and DASSH DAC for biological data). https://www.gov.uk/government/collections/marine-conservation-zone-designations-in-england.

  • This dataset contains level 1b altimetry data from the Synthetic Aperture Radar Altimeter (SRAL) aboard the European Space Agency (ESA) Sentinel 3B Satellite. Sentinel 3B was launched on the 25th of April 2018. These level 1b products are geo-located and fully calibrated multi-looked High-Resolution power echoes. Complex echoes (In-phase (I) and Quadrature (Q)) for the Low-Resolution Mode (LRM) and/or Synthetic Aperture Radar (SAR) mode both for C Band and Ku band. When the altimeter is in SAR mode, this product also contains the so-called Pseudo LRM (PLRM) echoes. All Sentinel-3 Non-Time Critical (NTC) products are available in less than 30 days. Data are provided by ESA and are made available via CEDA to any registered user.

  • Data generated by a range of scientific projects, including: UK Geoenergy Observatories in Glasgow & Cheshire: UK future energy monitoring and testing, Cardiff Urban Observatory: monitoring geothermal heat recovery and storage project, Seismic monitoring: a network of more than 100+ seismograph stations, River Thames ground water monitoring. BGS collect data from sensors located throughout the UK and beyond.

  • The Radio Acoustic Sounding System (RASS) messages data describe hourly observations from around 120 stations distributed globally. The observations, which are later transmitted in reports, give measurements of parameters such as wind speed, and temperature. The data are collected by observation stations worldwide and transmitted within the RASS message. Data are extracted daily at around 00 UT from the Met Office's MetDB system for the previous day's coverage. The dataset contains measurements of the following parameters: - Station height (in m) - Virtual temperature (in Kelvin) - Wind w velocity component (in m/s) - Signal to noise ratio See linked documentation for general information about surface station readings can be obtained from the abridged version of "MIDAS Data Users Guide", provided by the Met Office. This document describes the meteorological surface data in the Met Office Database - MIDAS. This guide is rich in information and is aimed at those with little familiarity with observing methods or instrumentation. Details of the WMO Meteorological codes used at weather observing stations (daily and hourly weather) explain the codes used in this dataset further are also linked to on this record.

  • Data were collected by the Chilbolton Facility for Atmospheric and Radio Research (CFARR) Present Weather Sensor from 21st of August 2009 to the present at Chilbolton, Hampshire. The dataset contains reports of current weather conditions and those over the last hour using both NWS (National Weather Service) and WMO (World Meteorological Organisation) weather codes.

  • Scanned images of the records of onshore Great Britain (or near shore) site investigation reports held in the BGS archives in paper, microfilm or digital format. The entire collections in BGS Edinburgh have been scanned, but in BGS Keyworth currently only new reports received since 2002. Scanning started in 2002 and is ongoing with new records being scanned and added to the collection. Images are stored in TIFF format (Tagged Image File Format). Indexed on the site investigation database and the boreholes within the report, and their images, are associated via the borehole database.

  • Database of palaeontological specimens, world-wide coverage, including both "Museum" and "Survey" fossil collections from Keyworth and Edinburgh. Development commenced in Autumn 2000 and is ongoing. The database currently contains over 100,000 entries, including half of the taxonomic reference collection held at BGS Keyworth. Internet search access is available on the BGS web site. Key fields in the dataset, many of which can be searched for, include, sample number, nature of sample, confidentiality, collector/donator & year, register details, locality information (including grid reference, map sheet etc.), stratigraphy, type status, identifications & authority and publication details.

  • Dual-polar products from the Met Office's Clee Hill C-band rain radar, Shropshire, England. Data from this site include augmented ldr (linear depolarisation ratio) and zdr (differential reflectivity) scan data (both long and short pulse), available from August 2018 to present. The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.

  • Dual-polar products from the Met Office's Hameldon Hill C-band rain radar, Lancashire, England. Data include augmented ldr and zdr scan data (both long and short pulse). The radar is a C-band (5.3 cm wavelength) radar and data are received by the Nimrod system at 5 minute intervals.
