  • The World Climate Research Program (WCRP) Coupled Model Intercomparison Project, Phase 6 (CMIP6) data from the Met Office Hadley Centre (MOHC) HadGEM3-GC31-MM model output for the "Assimilation run paralleling the historical simulation, which may be used to generate hindcast initial conditions" (dcppA-assim) experiment. These are available at the following frequency: Omon. The runs included the ensemble members: r10i1p1f2, r1i1p1f2, r2i1p1f2, r3i1p1f2, r4i1p1f2, r5i1p1f2, r6i1p1f2, r7i1p1f2, r8i1p1f2 and r9i1p1f2. CMIP6 was a global climate model intercomparison project, coordinated by PCMDI (Program For Climate Model Diagnosis and Intercomparison) on behalf of the WCRP and provided input for the Intergovernmental Panel on Climate Change (IPCC) 6th Assessment Report (AR6). The official CMIP6 Citation, and its associated DOI, is provided as an online resource linked to this record.

  • This is version v3.3.0.2022f of Met Office Hadley Centre's Integrated Surface Database, HadISD. These data are global sub-daily surface meteorological data. The quality controlled variables in this dataset are: temperature, dewpoint temperature, sea-level pressure, wind speed and direction, cloud data (total, low, mid and high level). Past significant weather and precipitation data are also included, but have not been quality controlled, so their quality and completeness cannot be guaranteed. Quality control flags and data values which have been removed during the quality control process are provided in the qc_flags and flagged_values fields, and ancillary data files show the station listing with a station listing with IDs, names and location information. The data are provided as one NetCDF file per station. Files in the station_data folder station data files have the format "station_code" The station codes can be found under the docs tab. The station codes file has five columns as follows: 1) station code, 2) station name 3) station latitude 4) station longitude 5) station height. To keep informed about updates, news and announcements follow the HadOBS team on twitter @metofficeHadOBS.

  • This dataset provides measurements of the cuticular pheromone, 7,11-heptacosadiene of individual female vinegar flies. The purpose of the dataset is to compare the levels between two sibling species, Drosophila simulans and Drosophila sechellia. Single female virgins were isolated from males at eclosion, aged five days, and then washed in hexane to extract cuticular hydrocarbons. The extracts were analyzed by gas chromatography relative to an internal standard. Full details about this nonGeographicDataset can be found at

  • Concentrations of total organic carbon (TOC), total petroleum hydrocarbons, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) were determined in 84 near-surface soils (5-20 cm depth) taken from a 255 km2 area of Glasgow in the Clyde Basin, UK, during July 2011. Total petroleum hydrocarbon ranged from 79-2,505 mg kg-1 (mean 388 mg kg-1; median 272 mg kg-1) of which the aromatic fraction was 13-74 % (mean 44 %, median 43 %) and saturates were 28-87 % (mean 56 %, median 57 %). Σ16 PAH varied from 2-653 mg kg-1 (mean 32.4 mg kg-1; median 12.5mg kg-1) and Σ31 PAH range was 2.47-852 mg kg-1 (mean 45.4 mg kg-1; median 19.0 mg kg-1). PCB tri-hepta range was 2.2-1052 mg kg-1 (mean 32.4 mg kg-1; median 12.7 mg kg-1) and the ΣPCB7 was 0.3-344 mg kg-1 (mean 9.8 mg kg-1; median 2.7 mg kg-1). This data is associated with the published research paper Kim, A.W., Vane, C.H., Moss-Hayes, V. Berriro, D.B., Fordyce, F., Everrett, P. Nathanail, P.C. 2018.

  • Radiocarbon ages of planktic and benthic foraminifera from sediment core EW9302-2JPC in the Northwest Atlantic from 0 to 30,000 years ago. Picked monospecific planktic foraminifera (G. bulloides and N. pachyderma) and mixed planospiral benthic formanifera (Cibicidoides, Melonis, Elphidium) were prepared to graphite at the NERC Radiocarbon Facility - East Kilbride and passed to the Keck Carbon Cycle AMS Facility, University of California, Irvine, USA for 14C analysis.

  • Major and trace element data of lava and tephra samples from the 2021 Tajogaite eruption. Major and select trace element collected by XRF, trace elements collected by ICPMS, both at the University of Granada. Data collected as part of NERC Urgency Grant led by K Chamberlain (Liverpool), in collaboration with M Pankhurst (INVOLCAN), J Scarrow (Granada), D Morgan (Leeds), J Hickey (Exeter), D Neave (Manchester), for understanding how eruptions begin, evolve and end. Samples analysed span the entire September - December 2021 eruptive sequence of Tajogaite, and data were collected between December 2021 and August 2022.

  • Groundwater and gas samples collected from sites in the Vale of Pickering and analysed for major gas concentrations, methane stable isotopes, and noble gas compositions.

  • X-discontinuity observations recorded from receiver function stacks of passive-source seismic data. Receiver functions are recorded between January 1990 and October 2021 at numerous seismometers on the African continent (see Pugh et al., 2023 for details). Receiver functions are downloaded, processed using SMURFPy (Cottaar et al., 2020). They are subsequently stacked in the depth and time-slowness domains in 1 degree radius overlapping bins and interpreted for the presence of the X-discontinuity. The dataset comprises 597 stacks, their location, the depth of the X-discontinuity, a classification of the stack and the amplitudes of the X-discontinuity. See Pugh et al., 2023 for further details on the method, the code used to download, process and stack receiver functions can be found at: Pugh et al., 2023 - Multigenetic Origin of the X-discontinuity Below Continents: Insights from African Receiver Functions.
