Gallery of Best Cloud-Free Days in California Current

• A script was run using Wimsoft software (http://wimsoft.com) to find the best daily coverage of satellite-detected surface Chl-a off Southern California, estimated by the number of valid pixels. Missing pixels are due to the combined effect of clouds and/or missing orbital coverage of the various satellite sensors.
• The command that produced the sorted list of the daily Chl-a images was: wam_count *mapped.hdf 60 - cal_aco_3840x3405_calcofi.hdf Sort
• Daily merged Chl-a data assembled from Aqua-MODIS, SeaWiFS and Terra-MODIS and available at http://spg.ucsd.edu/Satellite_California_Current/ were used in the script.
• The coverage (Count of valid pixels and % Clear) depends, of course, on the selected target area (mask). The Chl-a images themselves are much bigger and cover the west coast of North America from Oregon to southern Mexico.
• File naming details are provided in http://spg.ucsd.edu/Satellite_Data/California_Current/Readme.htm
• Some images show the artifacts of merging data from multiple sensors and multiple passes.
• Lower-quality data from Terra-MODIS are included (with a lower priority, i.e. when data from other sensors are missing) and are often the source of the visible artifacts.
• The list was compiled using data from 1997 to 28-Nov-2009.
• More information is available from mkahru @ ucsd.edu.
