You can select any period from one day to one year.<br /> <br /> You can also choose either a time series line graph showing values over time, or a wind plot showing average pollutant values depending on wind direction.<br /> <br /> Please be patient, requests for long time periods may take a long time to fetch, especially during busy periods.<br /> <br /> Make your selection from the boxes below and press 'View': <h3>Line Graphs</h3> <br /> <label for="site1">Select a site:</label> <select name="site" id="site1" tabindex="1"> <option></option> <option value="TD0">- National Physical Laboratory (closed 2018)</option> <option value="BG3">Barking and Dagenham -

New</h3> These are prototype visualisations of the annual objectives for monitoring sites, designed to be explored and to inspire comment: <ul> <li> The <a href="/LondonAir/Data-Visualisations/objectivevstime.aspx"> objectives over time graph </a> shows the trend in the selected objective at the selected subset of sites since 1993 when the LAQN started.</li> <li> The <a href="/LondonAir/Data-Visualisations/meanVSpeak.aspx"> mean verses peak graph </a> enables you to explore the relationship between the pollution around us across the year and the short peaks we sometimes get.</li> </ul> <h3>Air Quality Statistics</h3> These flexible statistical tools are designed to allow statistical analysis of the LAQN database for up to four sites at a time. The <strong>'Air Quality Objectives'</strong> tool assesses compliance with the Government's AQ Objectives over any twelve month period as defined by the start date. The <strong>'Air Quality Indices'</strong> tool calculates the number of days recorded in each Air Quality Index band over any period.<br /> <br /> The <strong>'Sustainability Indicator'</strong> tool calculates the indicator value over any twelve month period. Please note that there are a number of requirements that a monitoring site must meet before a regional indicator can be compared to the National Sustainability Indicator. Visit the <a href="https://www.gov.uk/government/organisations/department-for-environment-food-rural-affairs" target="_blank" title="Sustainable Development web site">Sustainable Development</a> web site for more information.</td> Alternatively, you can define statistics of your own. The <strong>'My own choice'</strong> tool is very flexible, allowing you to enter your own dates, averaging periods and even exceedence criteria. Give it a try and if there are any other calculations that you would find useful, please let us know and we may be able to add them.
