Evaluating the capabilities of modern machine learning techniques for operational over-ocean cloud masking with satellite imagers
Cloud detection is a fundamental first step in retrieving the geophysical properties of the Earth, determining which pixels contain clouds to generate a cloud mask. Analysis of passive imager missions contributing to the Global Energy and Water Cycle Experiment Cloud Assessments reveals slight …

Limb scatter measurements of high altitude cloud distributions
Clouds have pivotal influence on the Earth's hydrological cycle and climate system because they are intricately involved in the dynamical, chemical, and radiative processes within the upper troposphere and lower stratosphere. Cirrus clouds occur at high altitude around the tropopause level and, …

Efficient Detection of Cloud Scenes by a Space-Orbiting Argus 1000 Micro-Spectrometer
The description, interpretation and imagery of clouds using remote sensing datasets collected by Earth-orbiting satellites have become a great debate spanning several decades. Presently, many models for cloud detection and classification have been reported in the modern literature. However, none of …
