The Southern California Tribal Community Air Monitoring Network project will use community air grant funds to establish a monitoring network for Southern California Tribes in San Diego and Riverside Counties. As part of the project, three monitors will be placed on the Pala Reservation alongside existing monitoring equipment, initially, for calibration purposes. A total of six monitors will deployed over the first year. These monitors will be located on Tribal lands. The monitors are low voltage, small, approx 14"x12"x8". Each monitor will contain sensors from Alphasense to measure PM 2.5, PM 10, NO2, O3. They can be secured easily on a pole, building or home residence once permission from property owners is obtained. The data collection from these monitors will be displayed in real time, along with historical data, on a website that will be developed for this purpose. The monitors will collect data for PM 2.5, PM 10, NO2, O3. A yearly report will provide that analyzes the air quality data. In year two, the monitors will be reviewed and evaluated for potential relocation and a second yearly report provided. Finally, at the conclusion of the grant period, a community meeting will be held to discuss lessons learned, and next steps. Throughout this multiyear process, grant funds will also be used to facilitate collaboration with other tribes by providing outreach materials, workshops, and creation of a website for Tribal members and Tribal Air Program Managers will receive training, to build community capacity, on maintaining the monitors.
