On October 29, 2003, a shift in the winds over the Southwest U.S. sent smoke from the California wildfires (marked in red at left) northeastward to Nevada and eastward to Arizona. This modis.gsfc.nasa.gov Moderate Resolution Imaging Spectroradiometer (MODIS) image is from the terra.nasa.gov Terra satellite on the afternoon of Oct. 29.
The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at MODIS' maximum spatial resolution of http://rapidfire.sci.gsfc.nasa.gov/gallery/?2003302-1029/California.A2003302.2040.250m.jpg 250 meters.
