This dataset contains monthly average hours of fog and low cloud cover (FLCC) per day for North and Central Coastal California. The set of 42 grids has one for each summer month (June, July, August, and September) for each year (1999 - 2009), except for 2 missing months (June 2001 and August 2006) . Grid cell values were calculated using eleven years of hourly, day and night, cloud maps derived from geostationary operational environmental satellite (GOES) images collected and processed by the Cooperative Institute for Research in the Atmosphere (CIRA).
