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 ...

Assessment of CALIOP-Derived CCN Concentrations by In Situ Surface Measurements

Remote Sensing, 2022
The satellite-based cloud condensation nuclei (CCN) proxies used to quantify the aerosol-cloud interactions (ACIs) are column integrated and do not guarantee the vertical co-location of aerosols and clouds.

Assessing Cloud and Precipitation Properties on Temporal Scales Using LASSO Simulations Over the ARM Eastern North Atlantic (ENA) Site

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract The representation of low clouds and precipitation remains a major source of uncertainty in Earth System Models (ESMs), particularly due to challenges in representing their sub‐grid variability and scale‐dependent sampling. This study evaluates the performance of preliminary simulations from the Large‐Eddy Simulation (LES) Atmospheric ...

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.

Utilizing NASA's Operation IceBridge Airborne SWE and Precipitation Products to Assess Surface Snow Over Alaskan Glaciers

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Accurately estimating Snow Water Equivalent (SWE) in glacierized regions is critical for glacier modeling and mass balance analysis yet remains challenging due to sparse observations and uncertainties in precipitation products. The objectives are twofold: (a) assess how well three widely used precipitation datasets—Stage IV (a radar–gauge ...

Spaceborne observations of the lidar ratio of marine aerosols [PDF]

Atmospheric Chemistry and Physics, 2015
Abstract. Retrievals of aerosol optical depth (AOD) from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) satellite sensor require the assumption of the extinction-to-backscatter ratio, also known as the lidar ratio. This paper evaluates a new method to calculate the lidar ratio of marine aerosols using two independent sources: the AOD ...

Impacts of Maritime Continent Forest and Peat Fires on Regional Air Quality During 2019 CAMP2Ex Using MUSICAv0

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The NASA Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP2Ex) field campaign from 24 August to 05 October 2019 observed a complex mixture of aerosols—biomass burning smoke transported from Maritime Continent (MC)/Indonesia fires to the Philippines and Metro Manila's urban pollution.

Trends and Sensitivities of Low‐Cloud Cover and Top Height From Spaceborne Lidar Observations

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Low clouds effectively cool the Earth by reflecting incoming solar radiation. Detecting low‐level clouds with passive satellite sensors can be ambiguous, whereas active remote sensing instruments directly measure cloud‐top height. Here, we analyze 14 years of spaceborne lidar observations to assess trends in the occurrence of low‐level clouds ...

First EarthCARE CPR Observations of Dynamics–Microphysics Coupling in Marine Cold‐Air Outbreak Clouds

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Marine cold‐air outbreak (MCAO) clouds begin as shallow cloud streets near the ice edge and evolve into broken open‐cell convection downstream. Their rapid transitions in cloud structure and microphysics are closely linked to vertical motions, but this interplay has not previously been observed from space. The EarthCARE satellite, carrying the
