Weekend Edition: Smoke from Canada continues and DISCOVER-AQ Starts

The fires in British Columbia, Alberta and the Northwest Territories continue to pour smoke southward into the US. Code Orange AQI was seen in Alberta on Saturday morning. On the left below, the MODIS AQUA aerosol optical depth shows a streamer of smoke coming out of Alberta. The same image in the visible Red-Green-Blue image for the same overpass.

This same transport set up will lead to much cooler air coming into the US midwest this week.

In other air quality news, the DISCOVER-AQ experiment will begin on Monday in the Denver area. UMBC is out in Golden, Colorado, with two lidars and aerosol measurements. Below is an image of the new UMBC research trailer with Professor Chris Hennigan and students Jessica Izumi and Jared Johnson posing on the top. In addition, John Sullivan will be manning the GSFC Ozone DIAL research trailer in Fort Collins. Readers can follow along on the project by referring to our quicklook data page or to the project data page.

Update: July 13, 2014 20:00 MDT

Today's VIIRS image overlay from IDEA shows high AOD in British Columbia from the fires in that province. Earlier in the day, the area around Drumheller in Alberta had code orange AQI probably from smoke from the Canadian fires.

In Southern California, very high ozone was seen in San Bernadino and the high desert. AQI readings of 137 for ozone were logged.
