Earn Community Service Volunteer Hours with Vallejo Citizen Air Monitoring Network
Opportunity #1:
Build public speaking skills, get letters of recommendation, and be a part of making Vallejo’s environment safer and healthier. Volunteers will get training on local air quality issues and their health impacts. They will learn about basic video composition and create video presentations to disseminate to peers and social networks. Volunteers will be involved in information outreach and dissemination in virtual formats.
The hours and start date are flexible. The expectation is roughly 1-2 hours each week for 2-4 months.
Opportunity #2:
Gain technical training and hands-on experience with air quality monitor installation. Configure WiFi adaptors and connect routers. Be a part of a community driven effort to improve the air and the environment in Vallejo. Get letters of recommendation, leadership development, and enhance your professional profile.
The hours and start date are flexible. The expectation would be for a commitment of 6 months, averaging 5 hours a month
Welcome
Welcome
Welcome to the Vallejo Citizen Air Monitoring Network (VCAMN). We are a group of Vallejo residents working to make the air and environment better for all here in our community. We have monthly meetings open to all, and we welcome a diverse participation from all Vallejo residents including the voices of our youth. We have worked to build a network of air monitors in Vallejo to help us know when there is unsafe air around us, and to help us learn about potential problems and advocate for change to make our air and our health better.

Sensor Technology – Handheld XRF: How it works
XRF is an acronym for x-ray fluorescence, a process whereby electrons are displaced from their atomic orbital positions, releasing a burst of energy that is characteristic of a specific element. This release of energy is then registered by the detector in then XRF instrument, which in turn categorizes the energies by element.

Air District-operated monitor – How-to
The relatively poor air quality over the past week or two is mostly due to recent meteorology conditions. The persistent high pressure over California right now leads to cooler temperatures, a low inversion layer, light winds (no storms), and poor vertical mixing. This meteorology pattern traps our area’s emissions within the area and closer to the ground, leading to higher measured concentrations. Hopefully this will ease up a bit later this week.
I have passed along the information that the AirNow site is listing “Fairfield” on the Current AQI and AQI Loop of the “NowCast” values (as in the screenshot below). However, even though the header says Fairfield, the measured AQI listed on the AirNow page is not specific to any given monitor. The map and current AQI listed is the highest AQI measured for that hour at any site in the reporting zone for the zip code that is entered. There are five reporting zones in the Bay Area – and they are shown on the map here: http://www.baaqmd.gov/about-air-quality/current-air-quality and described here http://www.sparetheair.org/stay-informed/todays-air-quality/reporting-zones. Vallejo is in the Northern Zone, so for our AQI forecasts and AirNow current AQI, it is reflecting the maximum AQI in that whole area for a given day or hour.
I think a better site to track real-time measured concentrations at a specific Air District-operated monitor is the query page for the CARB AQMIS database located at https://www.arb.ca.gov/
