Multiyear On-Orbit Calibration and Performance of Terra MODIS Reflective Solar Bands
Xiaoxiong Xiong,Junqiang Sun,William L. Barnes,Vincent V. Salomonson,Joseph A. Esposito,H. Erives,B. Guenther +6 more
TL;DR: Results from the SDSM on-orbit observations show that the SD bidirectional reflectance factor (BRF) also has a similar wavelength-dependent degradation, with the largest degradation appearing at the shortest wavelengths.

An overview of MODIS radiometric calibration and characterization
TL;DR: The MODIS is a major advance over the previous generation of sensors in terms of its spectral, spatial, and temporal resolutions as mentioned in this paper, and is one of the key instruments for NASA's Earth Observing System (EOS), currently operating on both the Terra and Aqua satellites.

Terra and Aqua MODIS calibration algorithms and uncertainty analysis
TL;DR: An overview of MODIS on-orbit radiometric calibration approaches and a summary of the calibration uncertainties for both reflective solar bands (RSB) and thermal emissive bands (TEB) can be found in this paper.

Xiaoxiong Xiong,Amit Angal,William L. Barnes,Hongda Chen,Vincent Chiang,Xu Geng,Yonghong Li,Kevin A. Twedt,Zhipeng Wang,Truman Wilson,Aisheng Wu +10 more
TL;DR: In this paper, the authors provide a brief review of MODIS L1B calibration algorithms, including a number of improvements made in recent years, and present an update of sensor calibration uncertainty assessments with a focus on several new contributors resulting from on-orbit changes in sensor characteristics.
