Special Issue Information

Dear Colleagues,

The atmospheric profile provides valuable information regarding the structure, composition, and dynamics of Earth’s atmosphere. Since the late 1970s, remote sensing sensors have been developed to measure atmospheric trace gases and aerosols, thereby enhancing our understanding of the optical properties of aerosols and the three-dimensional transportation of pollutants and their chemical reactions. Remote sensing techniques also contribute to a better knowledge of the impact of aerosols on the vertical layer structure of the atmosphere and climate change through direct and indirect effects. The integration of observed three-dimensional data into atmospheric models through data assimilation techniques can further improve the accuracy of weather forecasts and air quality predictions. The study of air pollution and aerosol optical properties through atmospheric vertical profile remote sensing is also of importance for understanding the climate effects of aerosols, implementing air pollution control measures, and enhancing air quality predictions.

The primary objective of this Special Issue is to delve into the capabilities, limitations, and recent advancements in remote sensing for atmospheric vertical profiles. It aims to unravel the complexity of atmospheric vertical structures and their interactions with aerosols through remote sensing data and analyses of the optical properties of aerosols.

Articles may address, but are not limited to, the following topics:

  • Remote sensing aerosol retrieval algorithms;
  • Machine learning in atmospheric profile retrieval;
  • Vertical distribution, transport, and diffusion of aerosols;
  • Optical properties and radiative effects of aerosols;
  • Aerosol–cloud microphysics effects;
  • Assimilation of atmospheric vertical profile observations;
  • Simulation and validation of atmospheric vertical profiles;
  • Variations in boundary-layer aerosols;
  • Three-dimensional remote sensing in cities.

The climate impact of Arctic aerosols, like the Arctic Haze, and their origin are not fully understood. Therefore, long-term aerosol observations in the Arctic are performed. In this study, we present a homogenised data set from a sun and star photometer operated in the European Arctic, in Ny-Ålesund, Svalbard, of the 20 years from 2004–2023. Due to polar day and polar night, it is crucial to use observations of both instruments. Their data is evaluated in the same way and follows the cloud-screening procedure of AERONET. Additionally, an improved method for the calibration of the star photometer is presented. We found out, that autumn and winter are generally more polluted and have larger particles than summer. While the monthly median Aerosol Optical Depth (AOD) decreases in spring, the AOD increases significantly in autumn. A clear signal of large particles during the Arctic Haze can not be distinguished from large aerosols in winter. With autocorrelation analysis, we found that AOD events usually occur with a duration of several hours. We also compared AOD events with large-scale processes, like large-scale oscillation patterns, sea ice, weather conditions, or wildfires in the Northern Hemisphere but did not find one single cause that clearly determines the Arctic AOD. Therefore the observed optical depth is a superposition of different aerosol sources. Full article

The long-term atmospheric mixing layer height (MLH) information plays an important role in air quality and weather forecasting. However, it is not sufficient to study the characteristics of MLH using long-term high spatial and temporal resolution data in the desert. In this paper, over the southern edge of the Taklimakan Desert, the diurnal, monthly, and seasonal variations in the daytime MLH (retrieved by coherent Doppler wind lidar) and surface meteorological elements (provided by the local meteorological station) in a two-year period (from July 2021 to July 2023) were statistically analyzed, and the relationship between the two kinds of data was summarized. It was found that the diurnal average MLH exhibits a unimodal distribution, and the decrease rate in the MLH in the afternoon is much higher than the increase rate before noon. From the seasonal and monthly perspective, the most frequent deep mixing layer (>4 km) was formed in June, and the MLH is the highest in spring and summer. Finally, in terms of their mutual relationship, it was observed that the east-pathway wind has a greater impact on the formation of the deep mixing layer than the west-pathway wind; the dust weather with visibility of 1–10 km contributes significantly to the formation of the mixing layer; the temperature and relative humidity also exhibit a clear trend of a concentrated distribution at about the height of 3 km. The statistical analysis of the MLH deepens the understanding of the characteristics of dust pollution in this area, which is of great significance for the treatment of local dust pollution.
