Fire Pixels from MODIS, June 25-July 6, 2002
• Several satellite sensor (MODIS, GOES, AVHRR, ATSR…..) detect the location of most fires - DAILY• These ‘fire pixels’ can be used as sensor-based inputs to regional/global models, e.g. NAAPS• However, the quantity of smoke emitted from the from the ‘fire pixels’ can not be estimated well . • Hence, real-time model simulation of smoke transport is limited by the smoke emission estimates

SeaWiFS Hires: The Regional Picture
• Preceding and during the Quebec smoke event, there was a sulfate episode over the Eastern US.
• The Quebec smoke has a distinctly yellow color, different from the bluish sulfate haze.

July 6-7: Smoke plume signal is very intense over S. Ontario and NE US.
July 8-9: Transport to the Atlantic.
Where will the smoke reach Europe?
How intense, will it be detectable?
Would anyone run Hysplit, ATAD?
