Annually produced 1x1km background concentrations from Department for Environment, Food and Rural Affairs (Defra) national Pollution Climate (PCM) models. These are typically (but not uniquely) annual mean concentrations. The download webpage shows the years available for each pollutant and provides additional information on the relevant units/metrics. The model results are used in conjunction with measured concentrations from Defra's national monitoring networks to provide an air quality assessment that is reported to the European Commission in accordance with European Directives. The methodology and results are described in a mapping report published by Defra on UKAIR website. Note that these background maps are distinct from the source sector split concentration maps produced for Local Air Quality Management (LAQM) purposes and should not be used for LAQM operations.

Please use them in conjunction with reading the Background Maps User Guide. The projections in the 2018 LAQM background maps are based on assumptions which were current before the Covid-19 outbreak in the UK. In consequence these maps do not reflect short or longer term impacts on emissions in 2020 and beyond resulting from behavioural change during the national or local lockdowns.Only the most recent mapped data should be used for new air quality assessments.

The air quality indicator is one of the 68 indicators of the Government’s Sustainable Development Strategy. It measures annual levels of pollution from particulates (PM10) and ozone (O3), the two pollutants thought to have the greatest health impacts. In 2016 ONS proposed the cessation of these indicators due to limited use of these statistics: https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/articles/sustainabledevelopmentindicators/2015-07-13

The main cause of pollution in Middlesbrough is traffic. Although emission limits set for new cars are reducing the pollutants being emitted this is counteracted by the increasing number of cars on our roads. Controls on industry place limits on the emissions produced, and permits, regulation and enforcement ensure that these limits are adhered to.We monitor air quality at two static sites. Air quality analysers operate continuously to measure a number of pollutants, including those produced by vehicle exhausts such as nitrogen dioxide and PM10 particulates. The measured results confirm that Middlesbrough's air quality is often better than other towns and cities in Britain.In the event that measured levels of pollutants exceed the air quality objectives set by the government, an Air Quality Management Area must be declared. Middlesbrough's air quality has always met the objectives set and the town has never needed to declare an Air Quality Management Area. Monitoring will continue in order to ensure that current and future standards are met.It's also an objective of Middlesbrough Council to reduce pollution. Everyone can help by taking a few minutes to think of ways they can reduce pollution by making small changes to their lifestyle.There are a number of ways you can obtain up to date information regarding air quality in the borough.Through the Defra website you can see an overview of pollution levels in the north east along with detailed hourly data from the Breckon Hill air monitoring site in Middlesbrough.You can also get information regarding air quality in the north east of England by calling 0800 55 66 77 (freephone).Public Health and Public Protection ServicePO Box 505Civic CentreMiddlesbroughTS2 9FZTelephone (01642) 728272Email: EHTS@middlesbrough.gov.uk

Layer DescriptionThis layer contains the regional mean of the monthly maximum daily air quality index of particulate matter with diameter less than 10 µm (PM₁₀-DAQI) for 2003 to 2019 for UK regions, from the UK Air Quality Reanalysis dataset.This dataset forms part of the Met Office Air Quality Data Portal: https://air-quality-1-themetoffice.hub.arcgis.com/Temporal ResolutionThis is a monthly dataset, covering the period 2003 to 2019.Spatial ResolutionThis data is aggregated into regions. The regions correspond to the Office for National Statistics (ONS) International Territorial Level 2 regions for the UK (January 2021 BUC).Monthly maximum values have been calculated for each grid box. Regional values are then calculated as the weighted mean across all grid boxes included within the region. Weights are based on the proportion of the grid box area within the region.The UK Air Quality Reanalysis DatasetThe UK Air Quality Reanalysis has been generated as part of the SPF Clean Air Programme. It combines an air quality forecast model system with observations of pollutants to produce an enhanced representation of past pollutant concentrations across the UK over a long time period.The data covers the UK and Ireland at 0.1 degree horizontal resolution and hourly time resolution for the period 2003 to 2019.For further details of the dataset see: UK Air Quality Reanalysis.Please complete this quick questionnaire to give us some information about our users.The Daily Air Quality IndexThe Daily Air Quality Index (DAQI) is a scale used to describe the levels of air pollution and provide recommended health advice. It uses a scale from 1 (low pollution) to 10 (very high pollution). Further information about the DAQI can be found on Defra UK Air or in the Overview of Air Quality.Limitations of the DataThe reanalysis dataset is only representative of ambient background pollutant concentrations.The reduced temporal and spatial resolution means that short term pollution episodes, or highly localised fluctuations in pollutant levels are not captured by this data layer.Useful LinksFurther air quality information, data and applications can be found on the Met Office Air Quality Data Portal.For help exploring this data, see the Air Quality Data Portal User Guide.

This data set is a collection of estimated daily mean and maximum values for a range of air quality and meterological measurements and model forecasts for the UK and crown dependencies postcode districts (e.g. 'AB') for the years 2016-2019, inclusive.

The paper describing this dataset is available here: https://www.nature.com/articles/s41597-022-01135-6

The data uses a 'concentric regions' method to estimate the measurement for all regions, as follows. If measurements exist within the region, the mean of those measurements is used, if not, then a ring of neighbouring postcode regions are selected, and the mean of their measurement values used. If no measurement sites/data are found in the first ring, the process continues, taking the next ring of postcode district regions, working outwards until one or more sensors are found in a ring. As well as the measurement estimations, the number of rings required to find site data and make the estimations is also published. As a result, please note that estimations with higher ring counts ('rings') are likely to be calculated from more distant sensors. This distance depends upon the size of the postcode regions surrounding the location being estimated. Please use the ring count ('rings') to limit/filter estimations based on your required level of confidence.

The meteorological, pollen and air quality measurement data used to make the regional estimations can be found at this Zenodo archive. The data there contains Temperature, Relative Humidity, and Pressure data, downloaded from the Met Office MIDAS archives via the MEDMI server (https://www.data-mashup.org.uk/). Also downloaded from the MEDMI server are daily pollen measurements for the UK. PM10, PM2.5, NO2, NOx (as NO2), O3, and SO2 measurements from the DEFRA AURN network, and also model forecasts of the same made using the EMEP model.

The code used to make the estimations is available at this Zenodo archive.

The postcode data in postcode_district_data.csv are collated from several sources:

https://www.doogal.co.uk/UKPostcodes.php (population figures for the UK (UK Census 2011))

Department for Environment, Food and Rural Affairs (DEFRA) collect Carbon (CO2) Emissions figures nationally with a 2 year time delay. These figures are published on an annual basis at Local Authority level. This dataset contains Calderdale Carbon Emissions from 2005 to 2014 broken down by industrial and commercial, residential (including waste, housing and heating) and transport. Calderdale has a target to reduce the Total CO2 levels and Tonnes of CO2 per capita by 40% from 2005 to 2020. The 40% target is derived from UK government carbon reduction commitments set out under the Climate Change Act 2008 (the result of an EU directive and our assent of the Kyoto Protocol). The targets have in turn been adopted into an overall local strategy-the Calderdale Energy Future strategy. For further information see Calderdale's energy future The two Trajectory columns show progress to date and what reductions need to be achieved year on year to achieve this target.

Locations of Bristol City Council operated air quality monitoring sites, which defines the areas of poor air quality in Bristol. Data displayed is annual nitrogen dioxide (NO2) concentrations measured using diffusion tubes. Green dots indicate concentrations, for the latest year of data available, below the national annual objective for this pollutant of 40 ug/m3. Yellow indicate concentrations between 40 ug/m3 and 60 ug/m3 and exceed the annual objective for this pollutant. Red dots show those locations with concentrations greater than 60 ug/m3. Data are bias adjusted and annualised where required. Full details of air quality monitoring results are reported to Defra on an annual basis. The most recent reports on air quality in Bristol are available for download at: https://www.bristol.gov.uk/pests-pollution-noise-food/air-quality

Air quality management areas within Milton Keynes. Officers from the council’s Environment Health Team monitor a number of air quality pollutants in Milton Keynes and report the figures annually to DEFRA. This is a statutory function under the Local Air Quality Management (LAQM) regime set out in the Environment Act 1995.

Air quality is monitored continuously at several sites in and around the city with continuous analysers. Real time data from our air quality monitoring network, and from sites in Bristol that are part of the national network. Monitoring focuses on the key traffic pollutants as prescribed by the National Air Quality Strategy so the network is dominated by oxides of nitrogen (NOx) analysers which are located at roadside (<5m from kerb) locations and represent residential exposure.
