BRDF Estimations and Normalizations of Sentinel 2 Level 2 Data Using a Kalman-Filtering Approach and Comparisons with RadCalNet Measurements [PDF]

open access: yesRemote Sensing, 2021
BRDF estimation aims to characterize the anisotropic behaviour of the observed surface, which is directly related to the type of surface. BRDF theoretical models are then used in the normalization of the satellite-derived observations to virtually ...

Radiometric Top-of-Atmosphere Reflectance Consistency Assessment for Landsat 8/OLI, Sentinel-2/MSI, PROBA-V, and DEIMOS-1 over Libya-4 and RadCalNet Calibration Sites [PDF]

open access: yesRemote Sensing, 2019
There is a clear trend toward the use of higher spatial resolution satellite sensors. Due to the low revisit time of these sensors and frequent cloud coverage, many applications require data from different sensors to be combined in order to have more ...

Radiometric Calibration of Large-View-Angle Satellite Sensor at Railroad Valley Playa Site Despite Incomplete RadCalNet Datasets

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The radiometric calibration network (RadCalNet) datasets have been widely applied to calibrate the satellite sensor with a narrow field of view and monitor the radiometric performance during the on-orbit life cycle since the RadCalNet datasets have very ...

Identification of Global Extended Pseudo Invariant Calibration Sites (EPICS) and Their Validation Using Radiometric Calibration Network (RadCalNet)

open access: yesRemote Sensing
This study introduces a global land cover clustering using an unsupervised algorithm, incorporating the novel step of filtering data to retain only temporally stable pixels before applying K-means clustering.
