Select a site by clicking on it. This tool has been restricted to plotting one site at a time.

Select a variable by clicking on it. The pollutants available will depend on the selections of other parameters (e.g. site and date range selected). This tool is restricted to plotting one pollutant at a time.

Choose to enter either 'Specific Dates' or 'Specific Years'. 'Specific Dates' allow you to choose day, month and year to start and stop your analysis. 'Specific Years' will allow you to quickly choose the years of interest to you and the analysis will commence on 1st January and run until 31st December of those selected years.

Use this drop-down menu to select the way you want your data split. The default option will produce a single plot covering the entire range of the data. Selecting 'Hour' will produce an individual plot for each of the 24 hours throughout the day and so helps to represent diurnal differences. Selecting 'Weekday' will produce an individual plot for each day of the week and so is helpful in highlighting differences throughout the working week and weekends. Selecting 'Month' will produce an individual plot for each month of the year and so is helpful in highlighting differences throughout the year. Selecting 'Season' will split the plot into proper seasons showing the trend within seasons.

Select from a variety of set colour templates.
