A Drone‐Borne Method to Jointly Estimate Discharge and Manning's Roughness of Natural Streams
Image cross‐correlation techniques, such as particle image velocimetry (PIV), can estimate water surface velocity (v surf) of streams. However, discharge estimation requires water depth and the depth‐averaged vertical velocity (U m ).

Contrail Formation Within Cirrus: Contrail Induced Perturbations and Cirrus Adjustments
Abstract Contrail formation constitutes a large fraction of the aviation climate impact. But only part of the effect has been studied in detail, as research focused on contrail formation in cloud‐free air. Even though it is known that the impact of contrail formation within cirrus can be detected in space‐born remote sensing data, little research has ...

ABSTRACT The Nacho Nyäk Tagé (Stewart River) watershed in central Yukon (Canada) is characterized by discontinuous permafrost that is locally highly sensitive to thaw. This study aims to map the spatial distribution of permafrost terrain disturbances (PTDs) in the watershed and model thaw susceptibility to support community‐led land‐use planning by the

Abstract Recent aircraft observations of marine stratocumulus clouds consistently showed that cloud microphysical relationships vary with altitude, indicating inhomogeneous mixing characteristics near cloud top and homogeneous mixing characteristics in mid‐levels of clouds.

Radar System Development for Drone Borne Applications with Focus on Snowpack Parameters
A complete representation of the Arctic cryosphere has historically been restricted by its remoteness, large extent, and restrictions in measurement methods and equipment. Here, remote sensing of snow-cover is a central method to improve the current knowledge of the Earth's ecosystem, and hence a critical component in cryospheric models.
