WebNov 26, 2024 · It delivers modelled surface reflectance from Landsat 8 OLI-TIRS data using physical rather than empirical models. This ensures that the reflective value differences between imagery acquired at different times by different sensors will be primarily due to on-ground changes in biophysical parameters rather than artefacts of the imaging environment.

WebMay 18, 2024 · With the launch of Landsat 9 in September 2024, an optimal opportunity for in-flight cross-calibration occurred when Landsat 9 flew underneath Landsat 8 while being moved into its final orbit. Since the two instruments host nearly identical imaging systems, the underfly event offered ideal cross-calibration conditions. The purpose of this work … WebThe 7 and 9 day differences reflect how adjacent orbits laterally overlap at the Landsat swath edges and the 16 day difference is due to the 16 day Landsat repeat cycle. Other temporal differences are due to cloud obscuration between consecutive observations and periods of missing observations due to sensor and/or acquisition abnormalities.
