Air Quality Data - Unedited Hourly Concentrations

Special status notes:

IMPORTANT NOTE: As roads and parking lots dry out after the most recent application of sand & salt the residue can be stirred up by winds and traffic. Therefore, coarse particle pollution levels could be high nearby and downwind of roads & parking lots.


Use the form below to retrieve hourly air quality concentrations recorded from a number of ozone and particle (particulate matter 2.5) pollution monitoring stations across the State. This is "Raw" data which has not been converted to the Air Quality Index and is "preliminary."
