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 ...

Potentiality of Landsat-9 for early-season mapping of winter garlic and winter wheat
Geo-spatial Information ScienceLandsat-9 is the latest satellite of the Landsat program and provides useful agricultural remote sensing data. The earlier the crop distribution data is obtained, the greater the value of the data.

Evaluation of Landsat-9 interoperability with Sentinel-2 and Landsat-8 over Europe and local comparison with field surveys [PDF]
ISPRS Journal of Photogrammetry and Remote SensingThe recent launch of Landsat-9 satellite enriches the opportunities to work with dense time series of multispectral medium-resolution images. The integration of Landsat-9 in a multi-constellation series with Landsat-8 and Sentinel-2 requires a harmonization of the surface reflectance values that can be obtained from the official Level-2 products.

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

A Study on the Difference of LULC Classification Results Based on Landsat 8 and Landsat 9 Data
Sustainability, 2022 Landsat 9 enhances the radiation resolution of the operational land imager from the 12 bits of Landsat 8 to 14 bits. The higher radiation resolution improves the sensitivity of the sensor to detect many subtler differences, especially in the case of dense forests or water.

International 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.
