The minimum 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).
