If you get above 1x10^16 it is highly polluted. This is basically a duplicate of this question: earthscience.stackexchange.com/questions/9108/… | |

Of course, there are limit values set for NO2, but (as far as I know) only for concentrations [ug/m3]. To obtain ground-level concentrations from vertical column density to be able to confront them with the limit values is quite a complicated matter - and a different question. | |
