The Hawaii Department of Health on Wednesday posted an interactive map online to help visitors and residents learn of air quality conditions throughout the state.

The data taken from monitoring stations at strategic locations , the most of them on Hawaii Island.

“The unprecedented severity and duration of last summer’s Kilauea eruption pointed to the need for useful, accessible and reliable data for residents affected by the resulting vog and other effects of the volcano,” DOH said in a press release.

The department secured more than $1.5 million in federal and state funds to expand and upgrade the monitoring system.

The DOH’s Clean Air Branch works in conjunction with the State Laboratories Division on operation and maintenance of the statewide ambient air quality monitoring network.

National Air Quality Awareness Week is recognized from April 29 to May 3 this year.
