IACETH Seminar, Zurich, Kaiser et al., 31 Fire Radiative Power (FRP) produced from MODIS and SEVIRI directly proportional to emission [Ichoku 2005] [Wooster 2005]

IACETH Seminar, Zurich, Kaiser et al., 32 Some Conclusions

IACETH Seminar, Zurich, Kaiser et al., 33 Some Conclusions on Existing Fire Emission Models No global operational system exists. (Some) severe events of pollution with aerosol and CO can be monitored and forecast with observations of fires only. It is possible. Fire EO input is essential. High temporal frequency of fire observations is important.

IACETH Seminar, Zurich, Kaiser et al., 34 Some Conclusions on Fire Products No current product satisfies all requirements. LEO spatial coverage/resolution complements GEO temporal resolution. Hot spots (tropical forest) complement burnt area products. [C. Michel et al., JGR 2005] need regionalised approach Many existing products are inconsistent. [Boschetti et al. 2004] Several new operational products are anticipated. Fire Radiative Power from SEVIRI + global (M. Wooster) WF_ABBA from global GEO system (E. Prins) Burnt Area from MODIS (D. Roy) Burnt Area from VEGETATION (GDBAv1) Burnt Area from GEOLAND (BAG)

IACETH Seminar, Zurich, Kaiser et al., 35 GFAS Proposal A Global Fire Assimilation System (GFAS) is needed to combine several fire observations land cover products meteorological conditions a numerical model of fire activity. Such a system can provide the required fire input for the GMES atmosphere and land monitoring systems.

IACETH Seminar, Zurich, Kaiser et al., 43 Summary

IACETH Seminar, Zurich, Kaiser et al., 44 SUMMARY Wildfire, aka Biomass Burning (BB), emissions are needed globally in near-real time as well as in consistent multi-year time series. No suitable BB emission product is available. Principal shortcomings are accuracy, delivery time, temporal resolution, geographical coverage. Various fire observations complement each other. The development of a Global Fire Assimilation System (GFAS) is needed to serve the GMES requirements. Product generation needs to exploit existing observations more completely. FRP is very promising due to accuracy of emitted amount calculation and temporal resolution. Preliminary systems for fire emission modelling in GEMS are under development.
