The map shows the (predicted) current state of pollution from the power station at Selby, North Yorkshire.
The red line shows wind direction. Green rings show distance (km). Colours show concentration of particulates PM10 at ground level. Maximum: 160 pg/m3. This is the concentration at the location that is most polluted by the plume.
CO2 emission rate: 459 kg/s. This is approximately 232 m3/s: enough to fill 1673 typical houses every hour.
Breakdown of pollutants at most polluted location (green = background, red = added by plume):
Oxides of nitrogen

The emission rates were reported at 22:50 on Mon, 08 Aug 2022.
As well as the toxic pollutants in the plume, carbon dioxide (CO2) is currently being emitted at a rate of 459 kilograms per second. (How is this calculated?)
Each hour this is 1653 tonnes, equivalent to a volume of approximately 836328 cubic metres, which is enough to fill 1673 typical houses.
See here for an explanation of how these CO2 emissions are accounted for.
The map shows the predicted distribution of pollution. The key below the map shows the predicted concentration of the main pollutant at each location.
The text shows the maximum concentration of the main pollutant in the map area.
DETAILS shows maximum concentrations of all pollutants in the map area, compared with the existing background concentrations.
MORE DETAILS shows concentrations of all pollutants in more detail (in a new window).
The plume is modelled using Planned emission rates (e.g., from the planning application) or Historical emission rates (from emissions reports for a recent year).
The map can be zoomed in or out and can be Centred on the source or Downwind from the source.
