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 backscatter ratio measurements.

These data have been created by the Department for Environment, Food and Rural Affairs (Defra) and Joint Nature Conservation Committee (JNCC) in order to cost effectively provide high quality, Analysis Ready Data (ARD) for a wide range of applications. The dataset contains modified Copernicus Sentinel-1 data processed into a normalised radar backscatter product on a linear scale in dB. Products acquired from ESA are Ground-Range Detected (GRD) Interferometric Wide-swath (IW) in the dual VV+VH polarisation (DV) mode, where both VV and VH polarisations are collected. Defra and JNCC data were processed on separate platforms using a common specification to produce complementary outputs up to and including the acquisition date 23/06/2023. Data acquired after that date were processed on a single platform to the same specification. Sentinel-1 scenes processed before July 2021 have had a strip of data clipped from their northern edge to remove an artefact caused by a deprecated processing method. Details can be found in the lineage statement of the metadata for all affected scenes.

An international long-term collaboration to study the climatic and environmental feedback mechanisms involved in the African monsoon, and in some of its consequences on society and human health. The programme, which started in 2004, has developed a network of ground-based observation stations over Sub-Saharan West Africa to measure heat flux and, for some stations, CO2 and H2O vapour fluxes. Files also include concomitant meteorological measurements (wind, temperature, pressure, humidity, rainfall) and soil physics parameters (soil temperature and moisture). The UK branch of AMMA makes use of several instruments provided by the UK Universities Facility for Atmospheric Measurement (UFAM) which are centred on the Niamey meso-site. The Facility for Airbourne Atmospheric Measurements (FAAM) aircraft was used during the July-August 2006 campaign.

The data were collected by a Doppler Sodar, operated by the University of Leeds, at Barongartenhuette near Enzklosterle, Germany. The data provided are 15 minute averages of backscatter, horizontal wind and vertical wind. The dataset contains the following measurements: Wind speed Wind direction Eastward wind Backscatter Upward air velocity Height Northward wind

The data are nanoindentation, high-angular resolution electron backscatter diffraction (HR-EBSD), and transmission electron microscopy data collected on samples of synthetic forsterite bicrystals at room temperature. The data were collected in two samples, with high- and low- angle grain boundaries (HAGB, 60°, [100]/(011) and SB, 13°, [100]/(016)). The EBSD data are the basis for the HR-EBSD calculation. The HR-EBSD results are presented as Matlab data files. The nanoindentation data are categorised as a function of sample (‘ol13’ – low-angle grain boundary; and ‘ol60’ – high-angle grain boundary), and indenter tip geometry (spherical (with a 10 or 5 micron radius) and pyramidal (Berkovich). The data are presented in .xls files. The TEM data are presented as .tif files. The TEM data were collected in specific indents with various distances from the interfaces. These data have been published in the manuscript: : The Role of Grain Boundaries in Low-Temperature Plasticity of Olivine Revealed by Nanoindentation, with the DOI: 10.1029/2023JB026763

This Web service provides layers which show data relating to offshore survey activities undertaken by the British Geological Survey (BGS) and its predecessors. The layers are polygon, line and point layers which indicate the spatial areas of survey activities. The survey overview layer shows the location and basic information for coastal and marine surveys. It includes information about the survey, including the types of equipment deployed during the survey. For some surveys, a zip file of additional data can be downloaded using the URL link provided where available. The geophysical surveys layers show survey lines and shot points along those lines, where applicable. Geophysical surveys include shallow seismic reflection (e.g. airgun, boomer, pinger, sparker and water gun) and sonar (e.g. echo sounder, sidescan sonar and transit sonar). There may be several types of equipment deployed on a single survey line. Survey lines are uniquely named with a survey and line identifier (name or number). For example, 1985/6#16 is line 16 of survey 1985/6. The lines layer includes seismic reflection (sub seabed imaging which provides information about structures below the seabed) and sonar (seabed imaging which provides information about the roughness of the seabed or simple bathymetric data). Links to scanned images of geophysical records are provided (where available) for openly available survey lines where terms of use are known. The backscatter layer shows the location and basic information for bathymetric surveys containing backscatter data. A zip file of the backscatter image files for the survey can be downloaded using the URL link provided. Note that there can be more than one polygon per survey and these will link to the same zip file for the entire survey. The majority of the data were collected and processed for the Maritime and Coastguard Agency (MCA) under the Civil Hydrography Programme. To download the related bathymetry data go to the Admiralty Marine Data Portal (https://datahub.admiralty.co.uk/portal/apps/sites/#/marine-data-portal). The oil and gas industry site surveys layer shows the geographic location of oil and gas industry site surveys. The metadata for these surveys were collated via the BGS MEDIN Data Archive Centre (DAC). BGS do not hold the data. For further information contact the custodian of the data. For more information, contact BGS Marine Enquiries (offshoredata@bgs.ac.uk).
