The Rim Fire in California continues to be the headline of the day. NOAA Hazard Mapping System Fire and Smoke Product reported smoke from these fires along the northern Rocky Mountain and Great Plains states. The Google Earth overlay indicate the locations were light smoke was observed from satellite retrievals. AOD values reported by the MODIS sensor in NASA's Aqua satellite ranged from 0.4-1.0 over cloud-free locations. The smoke is also impacting air quality in locations near the fires, as shown in the EPA Airnow animation. The bottom left image is a PM2.5 timeseries for 2 air quality stations in Nevada, downwind from the fires. PM2.5 concentrations reported in these two locations, Sparks and Galletti, were greater than 60 ug/m3.
INCIWEB reported that smoke had the heaviest impacts to communities in the immediate fire area such as Groveland, Tuolumne City, Pinecrest, Bear Valley, and Greeley Hill in the morning hours. Due to a late increase in fire activity last night Pinecrest , Bear Valley, South Lake Tahoe, and Markleeville are likely to see higher smoke impacts than those seen on previous days. Last night's fire activity doesn't appear to have crossed the Sierra crest, so impacts this morning were mild in Reno, Carson City, and Minden, although smoke returned in the afternoon. Daytime transport winds will remain southwesterly, reducing impacts to the Yosemite Valley, El Portal, and the San Joaquin Valley. The fire is covering a total of 231,088 acres with about 70% of it contained.
