Air Quality Graphs & Wind Plots
These flexible graphing tools are designed to allow graphical analysis of the LAQN database. You can either plot measurements from up to six species (pollutants or meteorological parameters) at one site, or compare measurements of one species at up to six different sites. You can select any period from one day to one year. 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. Please be patient, requests for long time periods may take a long time to fetch, especially during busy periods.
