The maximum hourly annual value of NOx obtained from the records actually measured in each monitoring station with population representativity for gases (EMRPG). It is expressed in parts per billion (ppbv: unit of measure of concentration in volume, one part per billion) or micrograms per normal cubic meter (?g/m3N). The normal condition is the pressure of one atmosphere (1 atm.) and a temperature of 25 degrees Celsius (25ºC).
