Ocean subsurface studies with the CALIPSO spaceborne lidar [PDF]

Journal of Geophysical Research: Oceans, 2014
AbstractThe primary objective of the Cloud‐Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) mission is to study the climate impact of clouds and aerosols in the atmosphere. However, recent studies have demonstrated that CALIPSO also collects information about the ocean subsurface.

Consistent and scalable monitoring of birds and habitats along a coffee production intensity gradient

Remote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 686-700, December 2025.
Birds are commonly used as indicators of the effect of habitat degradation on biodiversity in the tropics. However, monitoring birds and their habitat in a way that is consistent, reliable and scalable remains an important challenge. Here, we examine whether bioacoustics and remote sensing can be used to efficiently monitor avian biodiversity and ...

Spatial distribution and drivers of aboveground forest biomass in Mexico using GEDI and national forest inventory data

Remote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 755-772, December 2025.
GEDI LiDAR‐derived biomass models were calibrated using local field data across various forest types in Mexico, resulting in a significant improvement in AGBD estimation accuracy compared to the standard GEDI products. The models reduced biomass estimation errors by over 30% and showed the highest accuracy in areas with moderate slopes and low forest ...

The Climatic Impacts of a Satellite‐Based Parameterization of the Wegener‐Bergeron‐Findeisen Process for Large‐Scale Models

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract A satellite‐based temperature‐dependent parameterization of the Wegener‐Bergeron‐Findeisen (WBF) process that takes into account the subgrid‐scale variability of cloud thermodynamic phase within mixed‐phase clouds is developed and implemented in version 5.3 of the Community Atmosphere Model (CAM5.3).

Characterizing ICESat‐2 Snow Depths Over the Boreal Forests and Tundra of Alaska in Support of the SnowEx 2023 Campaign

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Recent studies show that the Ice, Clouds, and Land Elevation Satellite‐2 (ICESat‐2) can achieve decimeter‐level accuracy over forested and mountainous sites in the western United States, as well as over the glaciers of Alaska. However, there has yet to be an assessment on ICESat‐2 snow depths over the boreal forests and tundra of Alaska, both ...

A U.S. Scientific Community Vision for Sustained Earth Observations of Greenhouse Gases to Support Local to Global Action

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Managing carbon stocks in the land, ocean, and atmosphere under changing climate requires a globally‐integrated view of carbon cycle processes at local and regional scales. The growing Earth Observation (EO) record is the backbone of this multi‐scale system, providing local information with discrete coverage from surface measurements and ...

Spaceborne remote sensing effectively maps species richness across taxonomic groups in a mountain landscape

International Journal of Applied Earth Observations and Geoinformation
Biodiversity decline due to global change poses a pressing challenge for conservation efforts worldwide. To improve the efficiency of conservation projects, spatially explicit information on species richness is needed, yet this information is challenging

Global Elevation Inversion for Multiband Spaceborne Lidar: Predevelopment of Forest Canopy Height

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Compared to single-band spaceborne lidars such as the global ecosystem dynamics investigation (GEDI) and Ice, Cloud and Land Elevation Satellite-2 (ICESat-2), multiband spaceborne lidars improve the detection of the canopy and ground.

Comparison of Cirrus Cloud Characteristics as Estimated by A Micropulse Ground-Based Lidar and A Spaceborne Lidar CALIOP Datasets Over Lille, France (50.60 °N, 3.14 ° E)

EPJ Web of Conferences, 2016
Our goal is to establish a climatology of cirrus cloud properties over Lille, France (50.60°N, 3.14 °E) using a ground-based lidar. A statistical analysis of mid-latitude cirrus clouds from lidar data in Lille over the period 2008-2013 is presented and ...
