Moderate AQI in the Great Lakes and west coast

Today, a huge portion of the nation is still covered by clouds and several inches of snow cover most of the mid-Atlantic and northeast region. Air quality conditions today are quite similar to those reported yesterday by Ruben. AirNow reported moderate PM2.5 levels mostly in the Great Lakes, some in the central valleys, north pacific and California, where even unhealthy levels for sensitive groups were reached (top left). According to the OMI group, high NO2 was retrieved in the central plains, northern and southern California (top right). Finally, no fires were detected across the US.

Continuing with Australia, Earth Observatory posted an interesting article about the massive fire that is taking place in the Snow River Complex:

Melbourne, Australia, has a new rival in night-time views from space (bottom left). The massive Snowy River Complex fire lights up the landscape over an area that nearly matches or possibly exceeds Melbourne in size. The fire in and around the remote Snowy River National Park is one of three high-priority bushfires that flared up in the state on February 9, 2014. A summer heat wave brought high temperatures and strong winds that combined with a dry environment to create dangerous fire conditions in Victoria. By February 12, more than 180,000 hectares (695 square miles) had burned, about 100,000 (390 square miles) of which burned in the Snowy River Complex. The other two fires--Morwell-Hernes Oak fire and the Mickleham-Kilmore--were much smaller but burned closer to populated areas. These images, acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite, provide a view of the fires by night and day on February 10, 2014. The Snowy River Complex is burning in mountain forests and is producing dense, opaque smoke that reflects enough moonlight to be visible in the night image. The daytime view shows a smoke plume stretching across the Tasman Sea to New Zealand.
