UAE United Arab Emirates, GER Germany. The given concentrations in the unit µg/m3 were calculated using the formula c (µg/m3) = 0.0409 × c (ppb) ×MW (g/mol) (at 1013.25 mbar and 25° C, c = concentration, ppb = parts per billion, MW = molecular weight, MW NO = 30.01 g/mol, MW NO2 = 46.01 g/mol). Standard deviations are stated in brackets. n/a = not available.
