AEROSOL CLASSIFICATION FOR TUCUMÁN AERONET STATION, ARGENTINA
Anales AFA, 2020 On November 15th, 2017, a new sunphotometer was installed for sensing and studying aerosols at National Meteo-rological Service headquarters in the City of Tucumán (26,787oS; 65,207oO), and was integrated to the AERONET/ NASA network. The north-central region of the country is mostly affected by both local and transported biomassburning events.

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

Depolarization ratios retrieved by AERONET sun–sky radiometer data and comparison to depolarization ratios measured with lidar [PDF]
Atmospheric Chemistry and Physics, 2017 The linear particle depolarization ratios at 440, 675, 870, and 1020 nm were derived using data taken with the AERONET sun–sky radiometer at Seoul (37.45° N, 126.95° E), Kongju (36.47° N, 127.14° E), Gosan (33.29° N, 126.16° E), and Osaka (34.65° N, 135 ...

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 ...

Observation of rapid aerosol deposition according to AERONET data [PDF]
E3S Web of Conferences, 2019 Measurements at the AERONET station in Dushanbe showed that the diurnal variations of the aerosol optical thickness (AOT), humidity, Ångström parameter depend on the stratification of the atmosphere. It is established that the dynamics of the aerosol in the ground inversion temperature layer is determined by the effect of double diffusion, which is ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract Accurate forecasting of PM2.5 (particulate matter with diameter ≤2.5 μm) and AOD550 (aerosol optical depth at 550 nm) is crucial for air quality management, public health, and environmental policy. Traditional physics‐based forecasting systems, though robust, require computationally intensive simulations and data assimilation (DA) schemes that

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.Abstract Decreases in anthropogenic aerosols will reduce fine particulate matter (PM2.5); however, meteorological feedbacks alter dust emissions, modifying air quality gains. We use eight Earth System Models from the Regional Aerosol Model Intercomparison Project (RAMIP) simulations to assess African climate and air quality responses to anthropogenic ...

Seasonal Variability of Precipitating Systems in Four Radar Domains of Northeast Brazil
International Journal of Climatology, Volume 46, Issue 6, May 2026.This study analyzes the climatology and evaluates how the physical aspects of precipitating systems are influenced by the dry and wet seasons in Northeast Brazil, highlighting seasonal variations in the frequency, size, intensity, and duration of these systems in the regions of Natal, Maceió, Petrolina, and Salvador.

Remote sensing of soot carbon – Part 2: Understanding the absorption Ångström exponent [PDF]
Atmospheric Chemistry and Physics, 2016 Recently, some authors have suggested that the absorption Ångström exponent (AAE) can be used to deduce the component aerosol absorption optical depths (AAODs) of carbonaceous aerosols in the AERONET database.

Meteorological Applications, Volume 33, Issue 3, May/June 2026.TURAAB: A 34‐year dust and atmospheric regional reanalysis for the Mediterranean–MENA region. We present TURAAB, a 34‐year, 6‐km regional reanalysis integrating meteorology and dust for the Mediterranean–MENA domain. The system demonstrates good behavior, aligning closely with observational and reanalysis products. TURAAB provides a high‐value resource
