Landsat 8 and 9 Underfly International Surface Reflectance Validation Collaboration
Remote SensingDuring the launch and path to its final orbit, the Landsat 9 satellite performed a once in a mission lifetime maneuver as it passed beneath Landsat 8, resulting in near coincident data collection.

Landsat-8/9 Atmospheric Correction Reliability Using Scene Statistics
Remote SensingLandsat data correction using the Land Surface Reflectance Code (LaSRC) has been proposed as the basis for the atmospheric correction of smallsats. While atmospheric correction can enhance smallsat data, the Landsat/LaSRC pathway delays output and may ...

Semi-Centennial of Landsat Observations & Pending Landsat 9 Launch
Photogrammetric Engineering & Remote Sensing, 2021 The first Landsat was placed in orbit on 23 July 1972, followed by a series of missions that have provided nearly continuous, two-satellite 8-day repeat image coverage of the Earth's land areas for the last half-century. These observations have substantially enhanced our understanding of the Earth's terrestrial dynamics, both as a major element of the
