Special Issue Information

Dear Colleagues,

Aerosols emitted from natural and anthropogenic sources can be transported thousands of miles downwind and affect the regional and global environments as well as the climate. In the atmosphere, aerosols alter the energy balance directly by absorbing and scattering both solar and terrestrial radiation and indirectly by modifying the micro- and macro-physical properties of clouds. Near the surface, aerosol particles can dramatically reduce visibility and worsen the air quality, both of which have harmful effects on humans. Additionally, these aerosol particles can deposit on snow/ice surfaces, and then accelerate snowmelt and influence the regional hydrological and energy cycles. Therefore, quantifying the atmospheric chemistry and transportation of aerosols can provide a better understanding of their environmental and climate impacts.

To the best of our knowledge, the atmospheric chemistry and transportation of aerosols are not fully known due to a lack of measurements as well as the limitations of the physical and chemical processes of aerosols in models. Recent developments in remote sensing and Earth system models have led to substantial advances in understanding atmospheric chemistry and the transportation of aerosols. 

This collection acts as a platform to share and investigate this topic area and provides the opportunity to quantify aerosol chemistry and transportation. This will help us to better understand the impacts of aerosols on the environment and climate.

We call for papers that can improve our understanding of the characteristics of aerosols using satellite remote sensing and the evaluations of modeled aerosols. We aim to quantify the characteristics of the atmospheric chemistry and transportation of aerosols using remote sensing data, including spatial distributions, radiative effects, etc.

Potential research topics include, but are not limited to, the following:

  • The microphysical and optical properties of aerosols.
  • Understanding the long-range transport characteristics of aerosols.
  • The vertical distribution of aerosol species (e.g., particle mass and size).
  • The impacts of light-absorbing aerosols in snow/ice.
  • The interaction of aerosol–cloud–precipitation–climate.
  • The impacts of meteorological parameters on the changes in aerosol species.
  • The effect of aerosols on extreme weather.

This Special Issue is the second edition of "Advances in Atmospheric Chemistry and Transportation of Aerosol by Remote Sensing and Modeling". Experts and scholars in related fields are welcome to submit their original works to this Special Issue.

The vertical profiles of aerosol optical properties are vital to clarify their transboundary transport, climate forcing and environmental health influences. Based on synergistic measurements of multiple advanced detection techniques, this study investigated aerosol vertical structure and optical characteristics during two dust and haze events in Lanzhou of northwest China. Dust particles originated from remote deserts traveled eastward at different altitudes and reached Lanzhou on 10 April 2020. The trans-regional aloft (~4.0 km) dust particles were entrained into the ground, and significantly modified aerosol optical properties over Lanzhou. The maximum aerosol extinction coefficient (σ), volumetric depolarization ratio (VDR), optical depth at 500 nm (AOD500), and surface PM10 and PM2.5 concentrations were 0.4~1.5 km−1, 0.15~0.30, 0.5~3.0, 200~590 μg/m3 and 134 μg/m3, respectively, under the heavy dust event, which were 3 to 11 times greater than those at the background level. The corresponding Ångström exponent (AE440–870), fine-mode fraction (FMF) and PM2.5/PM10 values consistently persisted within the ranges of 0.10 to 0.50, 0.20 to 0.50, and 0.20 to 0.50, respectively. These findings implied a prevailing dominance of coarse-mode and irregular non-spherical particles. A severe haze episode stemming from local emissions appeared at Lanzhou from 30 December 2020 to 2 January 2021. The low-altitude transboundary transport aerosols seriously deteriorated the air quality level in Lanzhou, and aerosol loading, surface air pollutants and fine-mode particles strikingly increased during the gradual strengthening of haze process. The maximum AOD500, AE440–870nm, FMF, PM2.5 and PM10 concentrations, and PM2.5/PM10 were 0.65, 1.50, 0.85, 110 μg/m3, 180 μg/m3 and 0.68 on 2 January 2021, respectively, while the corresponding σ and VDR at 0.20–0.80 km height were maintained at 0.68 km−1 and 0.03~0.12, implying that fine-mode and spherical small particles were predominant. The profile of ozone concentration exhibited a prominent two-layer structure (0.60–1.40 km and 0.10–0.30 km), and both concentrations at two heights always remained at high levels (60~72 μg/m3) during the entire haze event. Conversely, surface ozone concentration showed a significant decrease during severe haze period, with the peak value of 20~30 μg/m3, which was much smaller than that before haze pollution (~80 μg/m3 on 30 December). Our results also highlighted that the vertical profile of aerosol extinction coefficient was a good proxy for evaluating mass concentrations of surface particulate matters under uniform mixing layers, which was of great scientific significance for retrieving surface air pollutants in remote desert or ocean regions. These statistics of the aerosol vertical profiles and optical properties under heavy dust and haze events in Lanzhou would contribute to investigate and validate the transboundary transport and radiative forcing of aloft aerosols in the application of climate models or satellite remote sensing.
