Siberian Wildfires in 2012

animSiberia12.gif

The animation above shows the fire activity and smoke plumes in Siberia in during 10 June to 9 July 2012 and the consecutive transport of smoke across the Pacific, which was observed in several locations along the northern West Coast of the US, see for example http://www.huffingtonpost.cahttp://alg.umbc.edu/usaq/archives/004608.html and http://kplu.org/post/asian-fires-clouding-seattles-sunny-skiesMACC news. The MACC GFAS assimilation of Fire Radiative Power observations are superimposed over the combined organic matter and black carbon fields in the MACC global aerosol assimilation, which combines the smoke emissions calculated in GFAS with inventories of anthropogenic emissions and aerosol optical depth observations from space. Both types of observations are performed by the satellite-based MODIS instruments and NASA has provided the observation data. Details of the plotted dataset can be found in Kaiser et al. (Biogeosciences 2012) and Benedetti et al. (JGR 2009).

Siberia has experienced above-normal fire activity in April and May and the largest fire activity for 10-years in June and early July. This gives rise to a record for June even on the global scale. The plots below show the dry matter consumption of the wildfires in Siberia (top) and globally (bottom) from 1 January 2003 to 12 July 2012. Daily values are on the left and monthly values are on the right. Siberia is approximated by 50-75ºN, 60-190ºE.

Western US Wildfires in 2012

The Western US also experienced extraordinarily strong wildfire activity in May-July with more fire in June 2012 than in any other June during the last decade, see plots below. Daily values are on the left and monthly values are on the right. The Western US is approximated by 30-49ºN, 100-130ºW.

The Waldo Canyon, High Park, Last Chance and other Fires devastated large areas and many houses in Colorado, and several lives have been lost. The animation below shows the fire activity in Colorado during 16 June to 2 July 2012. On 27 June the Waldo Canyon fire near the centre of Colorado can be seen to expand eastward into the city of Colorado Springs. The data have been generated with Version 1.1 (0.1 deg resolution) of MACC's Global Fire Assimilation System (GFAS), which is based on space-borne Fire Radiative Power observations (Kaiser et al. Biogeosciences 2012). The observations are performed by the MODIS instruments aboard the Terra and Aqua satellites and have been provided by NASA.

Western Russian Wildfires in 2010

animRussia10.gif

The animation above shows the fire activity and smoke plumes in western Russia during the heat wave of July and August 2010; the MACC GFAS assimilation of Fire Radiative Power observations are superimposed over the smoke plumes in a MACC global aerosol model simulation that combines the smoke emissions calculated in GFAS with aerosol optical depth observations from space. Both types of observations are performed by the satellite-based MODIS instruments and NASA has provided the observation data. Details of the plotted dataset can be found in Kaiser et al. (Biogeosciences 2012), where it is described as "NRT analysis".
