Napa summer fog dissipates …

December 22, 2012



The retreat of early morning fog from the Napa Valley of California is shown in the sequence of images above for August 31, 2012 (8am to 9am local time). These 1km visible satellite images show albedo (amount of sunlight reflected from the surface). High albedo shows cloudy areas (depicted as white above). Low albedo indicates clear areas (shown as black above). These images were created by CNAP researcher Sam Iacobellis (click here to see more about Sam’s work with marine layer clouds). Summer fog is an important aspect of the climate that makes Napa a premium wine grape growing region. CNAP explores regional aspects of climate important to Napa and is pleased to collaborate with the Napa Valley Vintners and growers in the region such as David Graves of Saintsbury.
