Hurricane Harvey, PM and Ozone

Today was a bad day in Air Quality news all throughout the nation. Fires from British Columbia and much of the Pacific Northwest region of the States had been big contributors to the mass amounts of AOD moving east towards the Dakotas today (EOSDIS, top left). As fires continue in this area, with dense concentrations in Montana, Idaho and much of Washington, smoke is seen moving East and contributing to the overall elevated levels of PM observed as seen in the HMS image below (top right). In the Terra satellite imaging below (mid left), we see the heavy, dense concentration of smoke right over Washington state as fires continue producing plumes of smoke. The Pacific Southwest saw heightened levels of ozone (AirNow, mid right) in their respective areas as temperatures stayed high (NOAA climate chart, bottom left) and winds maintained low speeds. In the VIIRS CONUS AOD trajectory chart (bottom right), we see the mass amounts of PM from the Pacific Northwest circulating southeast further into the Rocky Mountain States and Northern Plain States. In the same trajectory, we can see Hurricane Harvey making its way through Texas as conditions worsen.
