These Landsat 7 composites are made from Level L1T orthorectified scenes, using the DN values, representing scaled, calibrated at-sensor radiance.
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 32-day period beginning from the first day of the year and
continuing to the 352nd day of the year. The last composite of the
year, beginning on day 353, will overlap the first composite of the
following year by 20 days. All the images from each 32-day period are
included in the composite, with the most recent pixel as the composite value.

Shortwave infrared 1
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.
