The average monthly concentration of NO2, obtained from the records actually measured at each monitoring station with population representation for gases (EMRPG). It is the temporal mean detected in the air and is expressed in parts per billion (ppbv: Unit of measure of concentration in volume, equivalent to one part per billion) or micrograms per normal cubic meter (µg/m3N). The normal conditions are a pressure of one atmosphere (1 atm.) and a temperature of 25 degrees Celsius (25ºC)".
