Aerosol-cloud interaction inferred from MODIS satellite data and global aerosol models [PDF]

Atmospheric Chemistry and Physics, 2007
We have used the MODIS satellite data and two global aerosol models to investigate the relationships between aerosol optical depth (AOD) and cloud parameters that may be affected by the aerosol concentration. The relationships that are studied are mainly

Improving satellite-retrieved aerosol microphysical properties using GOCART data [PDF]

Atmospheric Measurement Techniques, 2015
The Multi-angle Imaging SpectroRadiometer (MISR) aboard the NASA Earth Observing System's Terra satellite can provide more reliable aerosol optical depth (AOD) and better constraints on particle size (Ångström exponent, or ANG), sphericity, and single ...

Kernel‐Based Estimation of Stratospheric Aerosol Radiative Effects From Volcanic and Wildfire Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract To facilitate the quantification of the stratospheric aerosol direct radiative effect (ARE), this study develops a suite of aerosol kernels based on Modern‐Era Retrospective Analysis for Research and Applications, Version 2 reanalysis data. The kernels comprise a five‐dimensional data set that includes latitude, longitude, time, wavelength ...

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.

Evaluation of sun photometer capabilities for retrievals of aerosol optical depth at high latitudes: The POLAR-AOD intercomparison campaigns [PDF]

Atmospheric Environment, 2012
Accuracy requirements for aerosol optical depth (AOD) in polar regions are much more stringent tan those usually encountered in established sun photometer networks, while comparability of data from different archive centres is a further important issue.

Enhanced Adiabatic Heating Drives Faster Warming of Early Summer Hot Extremes in North China

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract North China has recently seen frequent hot days above 35°C or even 40°C before or at the very beginning of June. This raises a concern about the changing seasonality of exceptional hot extremes in the region which might leave population there underprepared.

Temporal and spectral cloud screening of polar-winter aerosol optical depth (AOD): impact of homogeneous and inhomogeneous clouds and crystal layers on climatological-scale AODs [PDF]

Atmospheric Chemistry and Physics, 2016
Abstract. We compared star photometry-derived, polar winter aerosol optical depths (AODs), acquired at Eureka, Nunavut, Canada and Ny-Ålesund, Svalbard with GEOS-Chem (GC) simulations as well as ground-based lidar and CALIOP retrievals. The results indicate significant cloud and/or low-altitude ice crystal (LIC) contamination which is only partially ...

Trend of North African Dust Storms and Potential Link to Climate Change

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Over recent decades, North African dust storms have undergone marked variability, reflecting complex interactions between regional climate processes and environmental change. Using four decades (1984–2023) of visibility‐based observational records, we examine regional and seasonal trends in dust storm frequency across the Sahel and the Sahara,

Evaluation of Aerosol Optical Depth (AOD) estimated by Copernicus Atmosphere Monitoring Service (CAMS) in Brazil

Theoretical and Applied Climatology
Abstract The optical depth of aerosols plays a crucial role in scientific research and environmental policies, making it possible to understand the distribution and extent of aerosols in various regions of Brazil. The objective of this study is to evaluate the estimates of Aerosol Optical Depth (AOD) from the Copernicus Atmosphere Monitoring ...
