Delamarter spent the day uncovering what goes into tracking air quality throughout our region..
She joins us live now in grants pass with an inside look at how it's done.
Right now, i'm at met one instruments in grants pass...today i spoke with several people here who monitor the air quality throughout our area.
Met one is actually a global company that offers instruments to monitor air quality inside and outside.
More than 25-thousand met one devices are in use across the world right now.
Here in oregon, there's 30 environmental protection agency sites...that measure air quality.
These devices are portable and often used by agencies like o- d-f to track the smoke in the air and how it will impact everyone nearby.
Some of these devices read air quality every 5 to 10 minutes.
"right now, this is going to tell you how bad the smoke is with respect to your breathing and affect low risk and high risk people and where that smoke is going."
Jen brown is the business scientist here at met one... she told me she's been tracking the smoke all week with these instruments... and she says she's noticed a pattern you've likely noticed as well, the air quality is usually much worse in the afternoon.
"i think that has a lot to do with the diagonal wind patterns we experience here in the valley.
So a lot of times in the afternoon the wind will get stronger when coming from the north which is where the fire is right now and it blows it in."
She says the smoke from the milepost 97 fire didn't reach the valley until last thursday afternoon... and since then the instruments have been reading an up and down air quality pattern every day.
Coming up tonight at 6, how this poor air quality is impacting those who have to work out in it every day... in grants pass, cassidy delamarter, newswatch12.
