OMI-Canadian smoke over eastern US
Archived post revisited: (July 7, 2006)
This post was kindly sent to us by Dr. Omar Torres from NASA-GSFC and UMBC-JCET. Note that these images are from the 3rd to the 7th.
"The images below show the rapid eastward movement of the Canadian fires. The AOD measured at the ground at GSFC has been relatively high (~ 0.7 at 380 nm) since late June and into July. There is not a clear jump in the last few days associated with the arrival of the Canadian smoke plume. My guess is that most of the AI high signal over GSFC is probably associated with height effect. At the Bondville site, on the other hand, the passage of the layer on July 6 was clearly seen at the ground where the AOT jumped from about 0.5 to almost 2.0 (see attached Aeronet plot)."

"The OMI Aerosol Index is a qualitative parameter that indicates the presence of UV-absorbing aerosols (mainly smoke and desert dust) at 2km or higher. The magnitude of the AI is directly proportional to the aerosol optical depth and layer height above the surface. OMI and TOMS Arosol Index data is available at http://toms.gsfc.nasa.gov."
