Daily Air Quality Index (AQI) Values for PM2.5
North Slope Borough Area Wide Air Quality Study
STUDY OVERVIEW
The North Slope Borough (NSB) Area Wide Air Quality (AQ) Study is a three-year study funded by the State of Alaska with the objective of collecting diverse baseline air quality data from five select villages on the North Slope of Alaska to determine the impact of the air quality on the health of the villages’ residents. This study began in October of 2023 and is currently scheduled to run through the end of 2025. The five villages participating in this study are Anaktuvuk Pass (AKP), Atqasuk (ATQ), Nuiqsut (NUI), Utqiagvik (BRW), and Wainwright (AIN). A map of where these villages are located on the North Slope can be seen in Figure 1 on the right.

AIR QUALITY INDEX
The AQI is the U.S. Environmental Protection Agency’s (EPA) Air Quality Index. The AQI is a numerical scale that uses six color-coded categories to represent the current air quality with green depicting the air quality as satisfactory. Table 1 (left) shows the current information about the AQI values for each criteria parameter and interval. For more details on the AQI, please visit AirNow’s resources here.

MONITORING LOCATIONS
The ambient air quality data for this study are collected primarily outdoors but also indoors at a school in each village. Data are collected from QuantAQ “Modulair” field sensors.
For villages with connectivity, Modulair data are transmitted back to Anchorage, AK on a weekly basis for analysis. For villages without remote communication, data are collected during semi-annual site visits. Details on the specific monitoring locations in each village can be found in Table 2 to the right.
