Bad AQI in Utah persists; Australia on fire!

Today, AirNow reported moderate and unhealthy levels for sensitive groups of PM2.5 in different regions such us the Great Lakes, Northeast and Mid-Atlantic regions as well as in California (top left). Air quality readings in Utah continue to show moderate to unhealthy levels during the day. Moreover, ozone levels in the same stations turned moderate and unhealthy levels for sensitive groups (top right). Some fires continue taking place in the US but none of them producing significant smoke (bottom left).



Regarding the fires in Australia, Earth Observatory published a couple of images captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite showing numerous fires across the continent on January 6, 2013 (left). Hundreds of uncontrolled fires also burned throughout New South Wales and Victoria, the two most populous Australian states. Three of the most intense were the Deans Gap fire, the Yarrabin fire, and the Cobbler Road fire (right). Extreme heat and strong winds have fueled the spate of fires. According to the Australian Bureau of Meteorology (BOM), the national average temperature on January 7 reached 40.3┬░Celsius (104.6┬░Fahrenheit), breaking a record set in 1972. Temperatures were so extreme that Australian meteorologists were forced to add additional color bands to their forecasting maps (bottom).
