The map below shows the current highest carbon monoxide 8-hour levels measured in parts per million (ppm) for each of the metropolitan or other areas across Clark County where carbon monoxide is measured by the DAQ. More detailed maps showing the current 8-hour carbon monoxide levels measured at each site in a particular area are available by clicking on the boxes on the map. These levels are based on data measured at the DAQ's continuous air monitoring stations and may include data from local governments and private monitoring networks.
The latest imagery available is for Tuesday February 28, 2017 01:00 PST.
