ADM-Aeolus pre-launch activities and recent advances in spaceborne and airborne Wind Lidar Systems [PDF]

open access: yes, 2016
The first space-borne wind lidar mission ADM-Aeolus from ESA is currently scheduled for launch by mid-2017. For the preparation of the Aeolus validation, an airborne field experiment was performed during 3 weeks in May 2015 with the DLR Falcon and the ...

Canopy Definitions Shape Canopy Space Filling–Productivity Relationships: Evidence From Terrestrial Laser Scanning

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The spatial arrangement of trees and their branches within the canopy is crucial for light interception, often resulting in a positive relationship between canopy space filling and stand productivity. To date, there is no universal definition of canopy space.

The end stage of barrier estuary infill: Insights from Jack Smith Lake, Southeastern Australia

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Infill model for the saline coastal lake estuary, Jack Smith Lake. Abstract Jack Smith Lake in southeastern Australia is an infilled saline coastal lake, disconnected from the ocean by a foredune barrier. This study explores the Holocene infill history of this estuary in order to understand the end‐stage evolution of barrier estuarine systems with ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Decadal Erosion Rates and Sediment Buffering Identified Through Enhanced DEM Differencing Using Underutilized Global Satellite DEMs

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Quantifying decadal‐scale erosion rates in tectonically active regions is essential for assessing landscape hazards and constraining sediment budgets. A key question in Earth surface processes is how contemporary erosion measurements influenced by recent climatic extremes relate to long‐term geological rates.

Reshaping of San Jose Island, TX, USA, by Unconfined Washover and Channelized Washout During Hurricane Harvey

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Hurricane Harvey (2017) produced 31 net‐erosional washout channels on San Jose Island, Texas, USA, where offshore‐directed flows cut through two dune ridges and the beach. Channel growth was affected by natural, pre‐existing aeolian topography, rather than prior washover channels or infrastructure. We investigate how offshore directed outwash,
