2003-09-28 The BigSmoke in New England, July 2002

  1. 1. The BigSmoke in New England, July 2002 Smoke transport from Quebec to New England to … <ul><li>An evolving presentation by a virtual community. Would you like add to this presentation? </li></ul><ul><li>Download this PPT presentation </li></ul><ul><li>Add your content, return to rhusar@me.wustl.edu </li></ul><ul><li>See also the Aerosol Events Website for discussion </li></ul>MODIS image
  2. 2. Fire Pixels from MODIS , June 25-July 6, 2002 <ul><li>Several satellite sensor ( MODIS , GOES , AVHRR , ATSR …..) detect the location of most fires - DAILY </li></ul><ul><li>These ‘fire pixels’ can be used as sensor-based inputs to regional/global models, e.g. NAAPS </li></ul><ul><li>However, the quantity of smoke emitted from the from the ‘fire pixels’ can not be estimated well . </li></ul><ul><li>Hence, real-time model simulation of smoke transport is limited by the smoke emission estimates </li></ul>Quebec Fires Note pixel clusters due to larger fires Manitoba – Sask. Fires Note pixel clusters due to larger fires SE US Fires Random pixels from small fires

  4. 4. SeaWiFS Hires: The Regional Picture <ul><li>Preceding and during the Quebec smoke event, there was a sulfate episode over the Eastern US. </li></ul><ul><li>The Quebec smoke has a distinctly yellow color, different from the bluish sulfate haze. </li></ul>020706SeaWiFS 020707SeaWiFS 020708SeaWiFS Sulfate Haze Sulfate Haze Sulfate Haze Smoke Smoke Smoke
