Multi-Modal and Multi-Temporal Data Fusion: Outcome of the 2012 GRSS Data Fusion Contest

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2013
The 2012 Data Fusion Contest organized by the Data Fusion Technical Committee (DFTC) of the IEEE Geoscience and Remote Sensing Society (GRSS) aimed at investigating the potential use of very high spatial resolution (VHR) multi-modal/multi-temporal image ...

Spaceborne Far‐Infrared Signal Simulations Over the Antarctic Plateau With Temperature‐Dependent Ice Cloud Optical Properties

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Longwave cloud radiative effects significantly influence variability in global and regional Earth systems. However, there have been very few, if any, measurements of the far‐infrared (FIR) radiation over the polar regions, where about half of the outgoing longwave radiation is in the FIR spectrum. This motivated the Polar Radiant Energy in the

Multi-Source Spaceborne LiDAR Forest Canopy Height Retrieval by Integrating GEDI and ICESat-2

Remote Sensing
Forest canopy height is critical for quantifying terrestrial carbon stocks, assessing ecosystem productivity, and supporting biogeochemical modeling. Spaceborne LiDAR missions (e.g., GEDI and ICESat-2) enable forest canopy height mapping from regional to

Concurrent Cloud and Drizzle Observations From Synergistic Ground‐Based Measurements

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Drizzle, a common feature of marine boundary layer clouds formed through collision‐coalescence, plays a key role in cloud microphysics and evolution. However, simultaneously retrieving cloud and drizzle properties from remote‐sensing observations remains challenging because drizzle droplets often dominate radar signals, masking cloud ...

Spaceborne Bi- and Multistatic SAR: Potential and Challenges [PDF]

, 2006
Bi- and multistatic synthetic aperture radar (SAR) operates with distinct transmit and receive antennas that are mounted on separate platforms. Such a spatial separation has several operational advantages, which will increase the capability, reliability ...

Toward Consistent Canopy Characterization From Low‐Cost UAV Imagery

Ecology and Evolution, Volume 16, Issue 9, September 2026.
We show that UAV‐based crown segmentation can reliably characterize dominant canopy trees in a structurally complex tropical forest. Focusing on these key individuals improves the assessment of forest structure and supports ecological monitoring at multiple scales. ABSTRACT Monitoring tropical forest structure at landscape scale requires cost‐effective

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Water Vapour Differential Absorption Lidar measurements at 935 nm using a Nd:YGG laser [PDF]

, 2010
A novel diode-pumped, single-frequency laser system emitting at 935 nm was developed to serve as the transmitter for water differential absorption lidar measurements. This laser uses Nd:YGG (Y3Ga5O12) as the active medium.

Cook's distance-guided neural network interpolation: enhancing spaceborne LiDAR data for forest canopy height mapping

International Journal of Digital Earth
Forest canopy height (FCH) is crucial for evaluating forest structure, carbon storage, biomass, and ecosystem dynamics, which can be derived by spaceborne LiDAR systems like Ice, Cloud and land Elevation Satellite-2 (ICESat-2) and Global Ecosystem ...

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...
