Machine learning-enabled real-time detection of cloud and aerosol layers using airborne lidar
Frontiers in Remote Sensing, 2023 Lidar profiling of the atmosphere provides information on existence of cloud and aerosol layers and the height and structure of those layers. Knowledge of feature boundaries is a key input to assimilation models.

Earth and Space Science, Volume 13, Issue 1, January 2026.Abstract Measuring and mapping vegetation structure is essential for understanding the functioning of terrestrial ecosystems and for informing environmental policies. Recent years have seen a growing demand for high‐resolution data on vegetation structure, driving their prediction at fine resolutions (1–30 m) at state, continental, and global spatial ...

Airborne lidar reflectance measurements at 1.57 μm in support of the A-SCOPE mission for atmospheric CO2 [PDF]
Atmospheric Measurement Techniques, 2009 The characteristics of the lidar reflectance of the Earth's surface is an important issue for the IPDA lidar technique (integrated path differential absorption lidar) which is the proposed method for the spaceborne measurement of atmospheric carbon ...

Determination of Structural Characteristics of Old-Growth Forest in Ukraine Using Spaceborne LiDAR
Remote Sensing, 2021 A forest’s structure changes as it progresses through developmental stages from establishment to old-growth forest. Therefore, the vertical structure of old-growth forests will differ from that of younger, managed forests.

New Phytologist, Volume 249, Issue 2, Page 829-847, January 2026.Summary Canopy reflectance captures plant traits related to ecological processes, which may reflect the composition of soil microbial communities. However, the extent to which canopy reflectance can help elucidate soil microbial community composition and diversity across biomes remains unclear. Using data from 14 National Ecological Observatory Network

Monitoring Bridge Vibrations via Spaceborne SAR Micro‐Doppler
Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.The advent of Synthetic Aperture Radar (SAR) imaging has presented the possibility of remote monitoring of civil infrastructure on a large scale. Although well established for observing slow and long‐term phenomena, its application to vibration‐based structural health monitoring (SHM) remains relatively unexplored in the current literature.

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.Abstract We produced global 0.25° three‐dimensional distribution of horizontal wind vectors (or 3D winds) by tracking water vapor from the hyperspectral infrared sounders and microwave sounders aboard two polar satellites (NOAA‐20 and Suomi‐NPP) that have overlapping tracks with time separation of 50 min.

A novel spaceborne lidar calibration technique: the multi-calibration lidar experiment [PDF]
International Conference on Space Optics — ICSO 2006, 2017 Although the noticeable progress achieved by ground-based lidars, using lidars as an operational spaceborne i nstruments still poses issu es to be solved. A key issue is the long-term stability of the instrument over the mission lifetime, as a whole as well as at the level of each subsystem; another important issue is related to the processes of ...

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.Abstract Ice‐ and mixed‐phase clouds play an important role in the global radiative budget and hydrological cycle, yet the complexity of ice crystal shapes and the presence of supercooled liquid water (SCLW) present challenges for retrieving cloud properties from airborne and spaceborne remote sensing instruments.
