These Landsat 7 composites are made from Level L1T orthorectified scenes, using the
computed top-of-atmosphere (TOA) reflectance. See Chander et al.
(2009)
for details on the TOA computation.
As of May 1, 2017, the USGS is no longer producing Pre-Collection Landsat, and therefore this collection is complete. Please switch to a Collection 1-based dataset. See this documentation page for more information.
These composites are created from
all the scenes in each
8-day period beginning from the first day of the year and continuing
to the 360th day of the year. The last composite of the year,
beginning on day 361, will overlap the first composite of the
following year by 3 days. All the images from each 8-day period are
included in the composite, with the most recent pixel as the composite value.

B6_VCID_1
60 meters
10.40 - 12.50 μm
Low-gain Thermal Infrared 1. This band has expanded dynamic range
and lower radiometric resolution (sensitivity), with less
saturation at high Digital Number (DN) values. Resampled from
60m to 30m.
B6_VCID_2
60 meters
10.40 - 12.50 μm
High-gain Thermal Infrared 1. This band has higher radiometric
resolution (sensitivity), although it has a more restricted dynamic range.
Resampled from 60m to 30m.
B7
30 meters
2.08 - 2.35 μm
Shortwave infrared 2
B8
