High‐Resolution Digital Terrain Model and Land‐Surface Parameters of São Sebastião and Ilhabela, Southeastern Brazil

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
The first openly accessible 2 m‐resolution lidar‐based DTM and an extensive set of land‐surface parameters (LSPs) for the region of São Sebastião and Ilhabela, southeastern Brazil, reveal geomorphological features previously indiscernible, including past landslide deposits, drainage captures and structural lineaments.

Evaluation of Tree-Growth Rate in the Laurentides Wildlife Reserve Using GEDI and Airborne-LiDAR Data

Remote Sensing, 2023
Loss of forest cover and derived effects on forest ecosystems services has led to the establishment of land management policies and forest monitoring systems, and consequently to the demand for accurate and multitemporal data on forest extent and ...

The Reflectance Distribution of Shallow Cumulus and Its Environs From High Spatial Resolution ASTER Images

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract We investigate the 1D reflectance distribution of shallow cumulus as a function of cloud size, using high‐spatial‐resolution observations from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). Reflectance transects through clouds are compared between Inner Mongolia and Tropical Ocean.

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 ...

Chlorophyll and POC in polar regions derived from spaceborne lidar

Frontiers in Marine Science, 2023
Polar regions have the most productive ecosystems in the global ocean but are vulnerable to global climate changes. Traditionally, the long-term changes occurred in an ecosystem are studied by using satellite-derived estimates of passive ocean color ...

Impact and Variability of Cloud Types on Earth's Top‐of‐Atmosphere Energy Balance in the Tropics: A 19‐Year Analysis of High‐Resolution CERES Data

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.
Abstract Cloud radiative effects (CREs) play a critical role in Earth's energy balance and climate variability, yet the variability and specific contributions of distinct cloud types remain poorly understood. Using the Clouds and the Earth's Radiant Energy System FluxByCldTyp data set, this study investigates how temporal variations in total top‐of‐the‐

PSLRC-Net: A PolInSAR and Spaceborne LiDAR Fusion Method for High-Precision DEM Inversion in Forested Areas

Remote Sensing
The Digital Elevation Model (DEM) is widely used in fields such as geoscience and environmental management. However, the existing DEMs struggle to meet the current requirements for timeliness and accuracy, especially in forested areas where vegetation ...

Detecting Change in Forest Structure with Simulated GEDI Lidar Waveforms: A Case Study of the Hemlock Woolly Adelgid (HWA; Adelges tsugae) Infestation

Remote Sensing, 2020
The hemlock woolly adelgid (HWA; Adelges tsugae) is an invasive insect infestation that is spreading into the forests of the northeastern United States, driven by the warmer winter temperatures associated with climate change.

In Situ Balloon‐Borne Observations of the Vertical Structure of Relative Humidity in Asian Summer Monsoon Cirrus Clouds

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The vertical structure of relative humidity within cirrus clouds in the upper troposphere remained unexplored, owing to measurement challenges. Twelve years of balloon‐borne simultaneous measurements of upper tropospheric humidity and optical particle backscatter during the Asian summer monsoon are used to consolidate our understanding of ...
