Global Diurnal Variation Characteristics of Aerosol Optical Depth From 32 Years of AERONET Observations

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Aerosols are ubiquitous microscopic particles in the atmosphere, and their diurnal variation characteristics reflect short‐term atmospheric changes that are crucial for climate monitoring and prediction. However, satellite, ground‐based, and reanalysis systems cannot simultaneously provide observational authenticity together with full temporal–

AEROSOL OPTICAL DEPTH (AOD) OVER FOUR INDONESIAN CITIES FROM THE AERONET MEASUREMENT: AN OVERVIEW

Jurnal Sains & Teknologi Modifikasi Cuaca, 2020
Abstract A large amount of aerosol, commonly known as Particulate Matter (PM), is emitted to the atmosphere from land-use conversion, urbanization, and the use of fossil fuels from a variety of sectors. Aerosol affect climate, environment, to human health.

Observed and Modeled Changes in Boundary‐Layer and Surface‐Level Actinic Flux Due To Wildfire Smoke Plumes in the California Central Valley in Summer 2018

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Wildfire smoke is increasingly degrading U.S. air quality via the emission and transport of pollutants. Smoke's direct role as a pollutant is well‐documented; however, smoke also affects pollutant concentration indirectly by changing the shortwave actinic flux necessary for photochemical reactions.

Significant Radiative Absorption of Brown Carbon Aerosols From Residential Fuel Combustion in Developing Regions

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Widespread household use of solid fuels releases massive amounts of carbonaceous aerosols in developing countries. Assessment of their roles in meteorology and climate change is considered low confidence by the Intergovernmental Panel on Climate Change.

Below‐Cloud CCN Concentrations Provide Better Constraints on the Twomey Effect Than Aerosol Optical Properties

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The primary uncertainty in anthropogenic climate forcing arises from a limited understanding of aerosol effects on cloud albedo, which in combination with other effects, is termed the radiative forcing from aerosol‐cloud interactions (RFaci).

Assessing Aerosol Wet Removal Efficiency in Conventional and Multiscale Modeling Framework Configurations of the Community Earth System Model

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Aerosol particles play a crucial role in the global climate by absorbing and scattering radiation and influencing cloud properties. This study explores the role of resolved convection on precipitation and subsequent removal by wet deposition of aerosol in the Community Earth System Model (CESM2.1.0) by comparing two configurations with ...

Retrieval of Aerosol Optical Depth Using Satellite Data Associated with Ground-based Observations over Urban and Rural Areas

Kartografija i Geoinformacije, 2019
Aerosol optical depth (AOD) can be retrieved accurately with sequential ground-based measurements of direct and diffuse solar radiance. However, spatial coverage and location frequency cause certain limitations.
