Angola PM2.5 Looks wrong

[CPBRA]

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:
