CAMS_44 “Development of the global fire assimilation system”


The Copernicus Atmosphere Monitoring Service (CAMS) has been developed to provide accurate monitoring and forecasting of atmospheric composition and air quality, which is of particular importance as air quality affects human health and life expectancy as well as the health of ecosystems. Dust, sand, smoke and volcanic aerosols, for example, affect the formation of clouds and rainfall, the safe operation of transport systems and the availability of power from solar generation.

The daily CAMS production of near-real-time analyses and forecasts of global atmospheric composition requires representation of the surface emissions from open biomass burning. Therefore, CAMS_44 and the European Centre for Medium-Range Weather Forecasts (ECMWF) provide the operational CAMS fire emission service in near-real-time. It uses the Global Fire Assimilation System (GFAS) and is based on satellite-based observations of Fire Radiative Power (FRP). GFAS provides data on fires and emission estimates of CO2, CO, CH4, soot, particulate organic matter, NOx, SO2 and other smoke constituents. The GFAS emissions are key inputs for all atmospheric models in CAMS, as well as other operational and scientific activities in Europe and beyond.

CAMS_44 furthermore develops updates to GFAS improve its accuracy in response to user requirements and keep track of the evolution of the satellite observing systems to provide service stability in the future. Fires are highly variable both in time and in space yet GFAS currently provides only daily mean output based on the observations of the day before. CAMS_44 is working to represent the diurnal fire variability, which is very pronounced with a maximum of the biomass burning activity during the early afternoon. Assimilation of fire observations from geostationary satellites will further improve the representation of the diurnal variability. The developments are also aiming at updating the GFAS service more frequently, and forecasting of fire emissions up to five days ahead. This will significantly enhance the accuracy and predictive power of GFAS and the atmospheric CAMS services.

Animation: Fire activity and smoke plumes in Siberia 10 June to 9 July 2012. The smoke was consecutively transported across the Pacific and to North America, see for example Huffingtonpost, US Air Quality smog blog and knkx. The GFAS assimilation of FRP observations are superimposed over the combined organic matter and black carbon fields. Details of the plotted dataset can be found in Kaiser et al. 2012 (Biogeosciences) and Benedetti et al. 2009 (JGR). The animation was first published during CAMS precursor MACC.
