CLARREO Pathfinder/VIIRS Intercalibration: Quantifying the Polarization Effects on Reflectance and the Intercalibration Uncertainty

Remote Sensing, 2019
Atmospheric scattering and surface polarization affect radiance measurements of polarization-sensitive instruments on orbit. Neglecting the polarization effects may lead to an inaccurate radiance/reflectance determination and underestimated radiance ...

Empirical Polarization Distribution Models for Use in CLARREO Pathfinder-VIIRS Intercalibration

Remote Sensing
In this work, we discuss the impact of polarized scene radiances on the intercalibration of CPF and VIIRS reflective solar bands and the mitigation of these effects using empirical Polarization Distribution Models (ePDMs).

The Moon as a Climate-Quality Radiometric Calibration Reference

Remote Sensing, 2020
On-orbit calibration requirements for a space-based climate observing system include long-term sensor response stability and reliable inter-calibration of multiple sensors, both contemporaneous and in succession. The difficulties with achieving these for

Retrieval of Vertical Cloud Droplet Profiles and Above-Cloud Integrated Water Vapor from Hyperspectral Measurements: Reducing Liquid Water Path Retrieval Bias with Application to EMIT

Remote Sensing
Accurate liquid water path estimates derived from backscattered solar radiation require knowledge of the vertical structure of cloud droplet effective radius, yet standard bispectral retrievals assume a vertically homogeneous cloud and overestimate ...
