Special Issue Information

Dear Colleagues,

Recent advances in LiDAR and remote sensing satellites have revolutionized the way we observe and understand atmospheric aerosols. Aerosols play a crucial role in climate regulation, air quality, and human health, yet their variability and impact remain challenging to characterize due to their complex spatial and temporal distributions. LiDAR, with its ability to provide high-resolution vertical profiles, has become an invaluable tool for aerosol monitoring, while remote sensing satellites offer large-scale, vertical observations that are essential for understanding aerosol transport and distribution globally. These technologies have greatly enhanced our ability to study aerosol properties, sources, and sinks, improving climate models and air quality predictions. The development of innovative LiDAR technologies and new satellite missions has pushed the boundaries of our knowledge, creating opportunities for more precise and comprehensive aerosol monitoring.

This Special Issue aims to bring together studies that leverage LiDAR and remote sensing satellites for atmospheric aerosol monitoring. We encourage submissions that demonstrate diverse uses of these technologies across different atmospheric conditions, scales, and regions. The objective is to foster a deeper understanding of aerosol properties, their spatial and temporal dynamics, and their effects on climate and air quality.

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

  • Development of novel aerosol monitoring technology;
  • Aerosol–cloud interactions and dynamics;
  • Aerosol change detection and long-term trends;
  • Aerosol optical and microphysical properties;
  • Carbon cycle/sequestration related to aerosols;
  • Aerosol dispersion effect and influence;
  • Aerosol radiative forcing and climate feedbacks;
  • Novel algorithms and machine learning techniques for aerosol detection;
  • Multispectral and hyperspectral approaches for aerosol characterization;
  • Regional and global aerosol transport modeling.

Aerosols are critical to the Earth’s atmosphere, influencing climate through interactions with solar radiation and clouds. However, accurately replicating the interactions between aerosols and clouds remains challenging due to the complexity of the physical processes involved. This study evaluated the performance of Coupled Model Intercomparison Project phase 6 (CMIP6) models in simulating aerosol optical depth (AOD), cloud fraction (CF), and liquid water path (LWP) by comparing them with satellite observations from MODIS and AMSR-E. Using 30 years of CMIP6 model simulations and available satellite observations during the satellite era, the results show that most CMIP6 models underestimate CF and LWP by 24.3% for LWP in the Northern Hemisphere. An assessment of spatial patterns indicates that models generally align more closely with observations in the Northern Hemisphere than in the Southern Hemisphere. Latitudinal profiles reveal that while most models capture the overall distribution patterns, they struggle to accurately reproduce observed magnitudes. A quantitative scoring system is applied to evaluate each model’s ability to replicate the spatial characteristics of multi-year mean aerosol and cloud properties. Overall, the findings suggest that CMIP6 models perform better in simulating AOD and CF than LWP, particularly in the Southern Hemisphere. Full article
