Evaluating the consistency of surface brightness, greenness, and wetness observations between Landsat-8 OLI and Landsat-9 OLI2 through underfly images

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2023
One important mission of the newly launched Landsat-9 is to collaborate with Landsat-8 to reduce the revisit period of Landsat Earth observations to eight days. This requires a high level of consistency between the two satellite data.

Land Surface Temperature Retrieval From Landsat 9 TIRS-2 Data Using Radiance-Based Split-Window Algorithm

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
The thermal infrared sensor-2 (TIRS-2) carried on Landsat 9 is the newest thermal infrared (TIR) sensor for the Landsat project and provides two adjacent TIR bands, which greatly benefits the land surface temperature (LST) retrieval at high spatial ...

Semi-Centennial of Landsat Observations & Pending Landsat 9 Launch

open access: yesPhotogrammetric 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

Landsat 9 Thermal Infrared Sensor 2 Preliminary Stray Light Assessment [PDF]

open access: yesIGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Although the Thermal Infrared Sensor 2 (TIRS-2) is a near-identical copy of the Landsat 8/TIRS-1 instrument, an important design change to the optical system was designed to mitigate the stray light issue that plagued the TIRS-1 instrument [1] 2, 3]. This change involved the addition of several baffles strategically placed within the optical telescope ...
