Potential of Spaceborne Lidar Measurements of Carbon Dioxide and Methane Emissions from Strong Point Sources

open access: yesRemote Sensing, 2017
Emissions from strong point sources, primarily large power plants, are a major portion of the total CO2 emissions. International climate agreements will increasingly require their independent monitoring.

Measurements of the effect of horizontal variability of atmospheric backscatter on dial measurements [PDF]

open access: yes, 1986
The horizontal variability of atmospheric backscatter may have a substantial effect on how Differential Absorption Lidar (DIAL) data must be taken and analyzed.

CNN‐Based Retrieval of 3D Cloud Structures Solely From Geostationary Satellite Imagery

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The cloud vertical structure (CVS) is important, yet operational CVS products depend on active observation or reanalysis fields, limiting high‐frequency monitoring. In this study, we propose a lightweight and satellite‐only model that reconstructs volumetric cloud masks from geostationary multispectral imagery.

Ratios of Extinction Coefficient, Mass, and Surface Area to Backscatter Coefficient and Mass to Extinction Coefficient Derived From Balloon‐Borne Stratospheric Aerosol Size Distribution Measurements From 1989–2025

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.
