The figure below shows the albedo (left panel) and albedo anomaly (right panel) as measured by
NOAA GOES retrievals. Albedo is defined as the amount (here in units of percent) of incoming solar
radiation reflected back to space. Clouds play the dominant role in the reflection of solar radiation
and for this reason albedo is a convienent proxy for cloud cover (e.g., more than normal cloud
cover will result in larger than normal values of albedo).
Maps are produced showing albedo and albedo anomaly averaged over the most recent 1, 5, 10, and 30-day periods for the regions shown in the adjacent figure. The red lines in the figures are major highways in the region. By default, this page will load the most recent 1-day period for the San Diego region. Under most circumstances the multi-day periods will be up to and including yesterday. Click on the links below for to view figures for different time periods and/or regions.
