The real-time monitoring data section features up to date particulate concentrations and internal meteorological conditions of currently deployed monitors. The data is updated hourly with 5-minute averages from the operating site.
There are two methods to obtain the real-time data:

BY UNIT NUMBER - If you know the unit number of the monitor you wish to view, select the “by unit number” drop down selection under the real-time data menu. You may also view the data by clicking on the “real-time data by unit number” to the right.

BY LOCATION – If you know the location of the monitor and not the unit number, select the “by location” drop down selection under the real-time data menu. A map of the United States will appear with dots indicating where current monitors are in operation. Individual states can be selected for a closer view where individual unit numbers can be selected.

The information displayed on the real-time data pages are neither quality checked nor quality assured for accuracy.
