Description
Landsat 7 Collection 2 Tier 1 and Real-Time data calibrated top-of-atmosphere (TOA) reflectance. Calibration coefficients are extracted from the image metadata. See Chander et al. (2009) for details on the TOA computation.
Note that Landsat 7's orbit has been drifting to an earlier acquisition time since 2017.
