      Hello all,

      Could somebody explain me how this would be possible ?

      546 micrograms/m³ ?

      Reading some articles I saw that the anual averege in Angola is 42 micrograms/m³ .

      Am'I reading this information wrongly ?

      Best Regards

        This high concentration of PM 2.5 is probably due to wildfires near north boarder. They are confirmed by NASA observation:

        And shown by CO layer on Windy:

        These fires increase the content of PM 2.5 as displayed in you post and also the NO2 as below:
