Fog and stratus along the entire West Coast of the US
GOES-11 0.65 µm visible channel images
GOES-11 0.65 µm visible channel imagery (above) indicated that you would have been hard pressed to find a location along the entire West Coast of the US (from California to Washington State) that did not have fog or stratus clouds overhead during the morning hours on 09 July 2010!
During the preceding night-time hours (before visible imagery was available), a comparison of AWIPS images of the 1-km resolution MODIS fog/stratus product and the 4-km resolution GOES-11 fog/stratus product centered over central California (below) demonstrated the value of higher spatial resolution in determining just how far inland some of the fog and stratus features were located at around 06:30 UTC (11:30 pm local time).
