These 1-year composites were created
from all Landsat 7 images in the specified composite period, excluding
images marked with a negative sun elevation in their metadata. The
composites were created using
the ee.Algorithms.Landsat.simpleComposite()
method with its default settings.
Reflectance ([0,1]) in bands B1, B2, B3, B4, B5, and B7 is scaled to 8 bits
([0,255]) and temperature in band B6_VCID_2 is converted to units of
Kelvin-100.
