Gallery of Best Cloud-Free Days in Drake
- A script was run using Wimsoft software (http://wimsoft.com) to find the best daily coverage of
satellite-detected surface Chl-a in the Scotia Sea and Drake Passage area, estimated by the number of
valid pixels. Missing pixels are due to the combined effect of clouds, ice,
low light and/or missing
orbital coverage of the various satellite sensors.
- Daily merged
Chl-a data assembled by Mati Kahru and available at
http://spg.ucsd.edu/Satellite_Data/Scotia_Sea/ was used in the script.
- The coverage
(Count of valid pixels and % Clear) depends, of course, on the
(mask) that was made to cover the Drake Passage. The images themselves are much
bigger and cover all the Scotia Sea and the surrounding areas. The mask
where cloud-free pixels are counted covers the AMLR region and is bounded by
white line (see below, left panel).
- Mean Chl-a is
shown below (right panel).
