The AQ stripes presented here show daily median pollutant concentrations at variaous sites across the UK on a grid of year against day of year. The top set of stripes show the absolute concentrations, whereas the bottom show the concentration difference from the grand median per day between 2015 - 2019. For example, the daily median on January 1st 2017 is compared to the median of the daily medians of each January 1st in 2015 - 2019
