Anthropogenic Pollution Accounts for a Substantial Part of Cloud Condensation Nuclei in North African Dust Layer

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Cloud condensation nuclei (CCN) modulate the properties and thus the climate effects of clouds. The North African dust plume is an important source of CCN in the North Atlantic trade‐wind zone. Yet, research into the nature and sources of these CCN is sparse, making it difficult to fully assess related cloud effects. Using combined airborne in

Applications of Satellite Data for Aerosol Optical Depth (AOD) Retrievals and Validation with AERONET Data

Atmospheric and Climate Sciences, 2011
An understanding of the amount and type of aerosols present in the atmosphere is required for the atmospheric correction of satellite imagery. A sensitivity analysis of the atmospheric inputs to the MOD09 software has shown that uncertainty in the estimation of Aerosol Optical Depth (AOD) has the greatest impact on the accuracy of atmospheric ...

An analysis of the collection 5 MODIS over-ocean aerosol optical depth product for its implication in aerosol assimilation [PDF]

Atmospheric Chemistry and Physics, 2011
As an update to our previous use of the collection 4 Moderate Resolution Imaging Spectroradiometer (MODIS) over-ocean aerosol optical depth (AOD) data, we examined ten years of Terra and eight years of Aqua collection 5 data for its potential usage in ...

Simultaneous Extraction of Planetary Boundary-Layer Height and Aerosol Optical Properties from Coherent Doppler Wind Lidar

Sensors, 2022
Planetary boundary-layer height is an important physical quantity for weather forecasting models and atmosphere environment assessment. A method of simultaneously extracting the surface-layer height (SLH), mixed-layer height (MLH), and aerosol optical ...

Retrieving Hourly Aerosol Absorption From Space Using Physical Informed Deep Learning

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Retrieving aerosol absorption properties, such as single scattering albedo (SSA) and absorption aerosol optical depth (AAOD) from single‐view satellite observations remains a significant challenge. This study introduces the Physics‐Informed Neural Network for Aerosols (PINA) framework to retrieve hourly aerosol absorption properties from ...

Long‐Term IASI Observations of Upper Tropospheric CO in the Asian Summer Monsoon Region: Trends and Eddy Shedding Signatures

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract The Asian Summer Monsoon (ASM) acts as a key mechanism for the vertical transport of surface pollutants into the upper troposphere (UT), which can have far‐reaching impacts on air quality and climate at regional to global scales. We analyze 16 years (2008–2023) of carbon monoxide (CO) observations from the Infrared Atmospheric Sounding ...

Quantifying the sensitivity of aerosol optical properties to the parameterizations of physico-chemical processes during the 2010 Russian wildfires and heatwave [PDF]

Atmospheric Chemistry and Physics, 2020
The impact of aerosol–radiation and aerosol–cloud interactions on the radiative forcing is subject to large uncertainties. This is caused by the limited understanding of aerosol optical properties and the role of aerosols as cloud condensation/ice nuclei

Differential Health Impacts of Short‐Term Particulate Matter Exposure in Arid and Semi‐Arid Regions: A Scoping Review

GeoHealth, Volume 10, Issue 6, June 2026.
Abstract Particulate matter (PM) exposure is a leading risk factor for cardiovascular and respiratory morbidity and mortality across the world. While arid and semi‐arid regions account for more than 40% of terrestrial land, there is a paucity of research investigating the relationship between PM exposure and health outcomes or how risk varies across ...

Comparison of Aerosol optical depth (AOD) derived from AERONET sunphotometer and Lidar system

IOP Conference Series: Earth and Environmental Science, 2014
Aerosol optical depth (AOD) is the measure of aerosols distributed within a column of air from the instrument or Earth's surface to the top of the atmosphere. In this paper, we compared the AOD measured by the Raymetrics Lidar system and AERONET sunphotometer.
