NowCast and 24-hour mean AQI

For hourly data from Clarity Nodes and Reference Monitors, we display the PM2.5 NowCast AQI. The NowCast AQI is an index developed by the US Environmental Protection Agency (US EPA) to estimate air quality conditions during a given hour, using a weighted-average of the past several hours of pollutant concentration data. The exact number of hours used is dependent on the variability of concentrations. Read more about EPA’s NowCast methodology here.

For daily data from Clarity Nodes and Reference Monitors, visible when viewing monthly or annual plots, we are displaying PM2.5 24-hour mean AQI, calculated using PM2.5 24-hour mean concentration. Data from the government reference network is being added to OpenMap through three sources: the AirNow, the European Environment Agency (EEA) and OpenAQ.

Who needs to be concerned?
Air quality is satisfactory, and air pollution poses little or no risk.
Some people who may be unusually sensitive to particle pollution.
Sensitive groups include people with heart or lung disease, older adults, children and teenagers, minority populations, and outdoor workers.
What should I do?
It’s a great day to be active outside.
Unusually sensitive people: Consider making outdoor activities shorter and less intense. Watch for symptoms such as coughing or shortness of breath. These are signs to take it easier.

Everyone else: It’s a good day to be active outside.
Sensitive groups: Make outdoor activities shorter and less intense. It’s OK to be active outdoors, but take more breaks. Watch for symptoms such as coughing or shortness of breath.

People with asthma: Follow your asthma action plan andkeep quick relief medicine handy.

People with heart disease:
Symptoms such as palpitations, shortness of breath, or unusual fatigue may indicate a serious problem. If you have any of these, contact your health care provider
Sensitive groups: Avoid long or intense outdoor activities. Consider rescheduling or moving activities indoors.*

Everyone else: Reduce long or intense activities. Take more breaks during outdoor activities.
Sensitive groups: Avoid all physical activity outdoors.
Reschedule to a time when air quality is better or move
