Maps cover the UK and Ireland at 2 km resolution in the Ordnance Survey National Grid (OSGB) projection. Maps are produced in near-real time, lagging by about one week. Data are available from early 2016 to 2023, on a daily basis. The model was calibrated on a network of cosmic-ray neutron sensors (COSMOS-UK) and remotely-sensed soil moisture data. A key parameter was estimated from the national-scale spatial pattern in the catchment response to rainfall seen in the National River Flow Archive (NRFA) data. Precipitation and humidity data to drive the model came from the Met Office High Resolution Numerical Weather Prediction model (NWP-UKV) which incorporates the C-band rainfall radar network. The maps have a variety of uses in hydrology and elsewhere, for example as inputs to ecosystem models of greenhouse gas exchange, where soil moisture affects numerous processes. The modelling was carried out as part of UK-SCAPE Virtual Survey Lab, and the NERC project 'Detection and Attribution of Regional Emissions (DARE-UK)'. There are some gaps in the time series of meteorological and remote sensing inputs, and data are unavailable for these days. The NRFA data are only available for Great Britain, so estimates in Ireland and continental Europe will be less accurate." ; dcterms:provenance [ a dcterms:ProvenanceStatement ; rdfs:label "We developed a statistical model of soil moisture, calibrated on a network of cosmic-ray neutron sensors in the UK. We found that applying an exponentially-weighted moving-average filter effectively linearised the effect of precipitation, so we could form a simple linear model. With this, we integrated remotely-sensed soil moisture data. To extrapolate across the whole country, we inferred information on the soil water retention properties from daily water balance data from approximately 1200 catchments with wide coverage. We used a Bayesian approach to allow the uncertainty from the calibration at 40 sites to be propagated through the extrapolation on a grid covering the whole UK. The Met Office High Resolution Numerical Weather Prediction model (NWP-UKV), which incorporates the C-band rainfall radar network, provides very detailed data on the variation in precipitation which arises from the sporadic nature of rainfall events and interactions with orography in near-real time, to predict small-scale, short-term variation in soil moisture." ] ; dcterms:spatial [ a dcterms:Location ; dcat:bbox "POLYGON((-8.648 49.864, -8.648 60.861, 1.768 60.861, 1.768 49.864, -8.648 49.864))"^^geo:wktLiteral ; ] ; dcterms:temporal [ a dcterms:PeriodOfTime ; dcat:startDate "2016-01-01"^^xsd:date ; dcat:endDate "2023-12-31"^^xsd:date ; ] ; dcat:contactPoint ; dcterms:publisher ; dcterms:subject "UK", "NRFA", "SCAT-SAR", "ASCAT", , , , "soil water retention curves", "rainfall", "hydrological modelling", , , , , , , , , ; prov:wasGeneratedBy :5aa8c5b4-4485-4954-b5c3-18d937a418f7_fund0, :5aa8c5b4-4485-4954-b5c3-18d937a418f7_fund1 ; a dcat:Dataset; dcterms:type dcmitype:Dataset ; dcterms:available "2024-05-08"^^xsd:date ; dcat:landingPage , ; dcterms:license ; dcterms:accessRights ; dcterms:theme , , ; dcat:distribution [ dcat:accessURL ; dcterms:license ; dcterms:accessRights ; dcterms:format [ a dcterms:IMT ; rdf:value "TIFF" ; rdfs:label "TIFF" ] ; ]; dcterms:creator ; dcterms:language . a foaf:Person ; foaf:name "Levy, P.E." ; foaf:familyName "Levy" ; foaf:givenName "P.E." ; vcard:hasEmail "enquiries@ceh.ac.uk" ; foaf:member ; . a foaf:Organization ; foaf:name "NERC EDS Environmental Information Data Centre" ; vcard:hasEmail "info@eidc.ac.uk" ; foaf:member ; . a foaf:Person ; foaf:name "Levy, P.E." ; foaf:familyName "Levy" ; foaf:givenName "P.E." ; vcard:hasEmail "enquiries@ceh.ac.uk" ; foaf:member ; . a skos:Concept; skos:prefLabel "Soil"; rdfs:label "Soil" . a skos:Concept; skos:prefLabel "Hydrology"; rdfs:label "Hydrology" . a skos:Concept; skos:prefLabel "Mapping"; rdfs:label "Mapping" . a skos:Concept; skos:prefLabel "soil moisture"; rdfs:label "soil moisture" . a skos:Concept; skos:prefLabel "soil water"; rdfs:label "soil water" . a skos:Concept; skos:prefLabel "modelling"; rdfs:label "modelling" . a skos:Concept; skos:prefLabel "soil"; rdfs:label "soil" . a skos:Concept; skos:prefLabel "hydrology"; rdfs:label "hydrology" . a skos:Concept; skos:prefLabel "atmospheric precipitation"; rdfs:label "atmospheric precipitation" . a skos:Concept; skos:prefLabel "catchment"; rdfs:label "catchment" . a skos:Concept; skos:prefLabel "mapping"; rdfs:label "mapping" . a skos:Concept; skos:prefLabel "remote sensing"; rdfs:label "remote sensing" . a foaf:Organization ; foaf:name "UK Centre for Ecology & Hydrology" . :5aa8c5b4-4485-4954-b5c3-18d937a418f7_fund0 a prov:Activity ; . :5aa8c5b4-4485-4954-b5c3-18d937a418f7_fund1 a prov:Activity ; .
