The Amazon River‐Breeze Circulation Limits Detection of Aerosol‐Cloud Interactions in Warm Clouds

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Increased aerosol concentrations can brighten low‐level clouds and extend their lifetimes, but aerosol–cloud interactions (ACI) remain highly uncertain and difficult to quantify. We show that part of this uncertainty is caused by topographical influences on clouds, that is, those arising from land–water contrasts.

Water vapor lidar [PDF]

The feasibility was studied of measuring atmospheric water vapor by means of a tunable lidar operated from the space shuttle. The specific method evaluated was differential absorption, a two-color method in which the atmospheric path of interest is ...

How do CMIP6 Models Represent the Vertical Structure and Chemical Properties of Biomass‐Burning Aerosols Emitted in Central Africa?

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract CMIP6 climate models have difficulties representing the strong absorption properties of biomass‐burning aerosols (BBA) over the Southeast Atlantic and the associated direct forcing. This study takes advantage of unique in situ and remote sensing observations to evaluate the vertical profile and chemical composition of BBA, which are key ...

Altitude range resolution of differential absorption lidar ozone profiles

Applied Optics, 1999
A method is described for the empirical determination of altitude range resolutions of ozone profiles obtained by differential absorption lidar (DIAL) analysis. The algorithm is independent of the implementation of the DIAL analysis, in particular of the type and order of the vertical smoothing filter applied.

Monte Carlo Simulation of 3D Cloud Radiance Distributions Affected by Ground‐Based Lighting

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Satellite observations of artificial light sources at night are increasing. Clouds, as the most important radiative modulators in the Earth‐atmosphere system, significantly influence the observed values and spatial distribution of the artificial light coming from the ground.

Design study for an airborne N₂O lidar [PDF]

Atmospheric Measurement Techniques
Nitrous oxide (N2O) is the third most important greenhouse gas modified by human activities after carbon dioxide and methane. This study examines the feasibility of airborne differential absorption lidar to measure N2O concentration enhancements over ...

Bistatic LIDAR system for the characterisation of aviation-related pollutant column densities [PDF]

, 2014
In this paper we investigate an innovative application of Light Detection and Ranging (LIDAR) technology for aviation-related pollutant measurements. The proposed measurement technique is conceived for the high-resolution characterisation in space and ...

Hemispheric Synoptic Patterns Control Rainfall and Long‐Range Aerosol Transport in the Amazon

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The transatlantic transport of dust and smoke aerosols from Africa to South America is a large‐scale, year‐round process that affects atmospheric and nutrient cycling in the Amazon rainforest. We analyze daily variations in black carbon at the Amazon Tall Tower Observatory (ATTO) to investigate how Atlantic synoptic‐scale meteorology ...
