FY-3D MERSI On-Orbit Radiometric Calibration from the Lunar View [PDF]

Sensors, 2020
Limited by the on-orbital calibration capability, scaling the measured radiance in accuracy and stability is challenging for the Earth observation satellites in the reflective solar bands (RSBs).

Rank-Based Radiometric Calibration [PDF]

Color and Imaging Conference, 2018
Raw images are more useful than JPEG images for machine vision algorithms and professional photographers because raw images preserve a linear relation between pixel values and the light measured from the scene. A camera is radiometrically calibrated if there is a computational model which can predict how the raw image is mapped to the corresponding ...

Landsat-7 ETM+ Radiometric Calibration Status. [PDF]

Proc SPIE Int Soc Opt Eng, 2016
Now in its 17th year of operation, the Enhanced Thematic Mapper + (ETM+), on board the Landsat-7 satellite, continues to systematically acquire imagery of the Earth to add to the 40+ year archive of Landsat data. Characterization of the ETM+ on-orbit radiometric performance has been on-going since its launch in 1999.

Image Navigation for FY-4A Lightning Mapping Imager

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Navigation of images from lightning mapping instruments in geostationary orbits is very important for data applications. However, few scientific peer-reviewed papers have been reported, except a few works in the prelaunch tests.

Preliminary Selection and Characterization of Pseudo-Invariant Calibration Sites in Northwest China

Remote Sensing, 2020
Pseudo-invariant calibration sites (PICS) have been used for the radiometric calibration and stability monitoring of satellite optical sensors. Several stable PICS, such as those in the Sahara Desert in North Africa, were selected for the vicarious ...

Study of the Application of FY-3D/MERSI-II Far-Infrared Data in Wildfire Monitoring

Remote Sensing, 2023
In general, the far-infrared channel in the wavelength range of 10.5–12.0 µm plays an auxiliary role in wildfire detection as its sensitivity to high-temperature targets is far lower than the mid-infrared channel in the wavelength range of 3.5–4.0 µm at ...
