Short Summary

This study investigates the impacts of aerosols on the macro- and microphysical properties of different cloud types over East Asia using nine years of satellite and reanalysis data, revealing pronounced cloud-type dependent effects and significant aerosol influence independent of meteorological conditions.

Objective

• To investigate the impacts of aerosols on the macro- and microphysical properties of different cloud types over East Asia.

Study Configuration

• Spatial Scale: East Asia
• Temporal Scale: Nine years

Methodology and Data

• Models used: Not applicable (ERA5 is a reanalysis data source, not a model run by the study)
• Data sources: Joint satellite observations from CloudSat, CALIPSO, and MODIS; ERA5 reanalysis data

Main Results

• Aerosol effects on cloud fraction, cloud top height, and cloud thickness show pronounced cloud-type dependence.
• Aerosols enhance the development of convective clouds.
• Aerosols suppress the vertical extent of stable stratiform clouds.
• For ice-phase structures, ice cloud fraction and ice water path significantly increase with aerosol optical depth (AOD) in deep convective and high-level clouds.
• Mid- to low-level clouds exhibit reduced ice crystal effective radius and ice water content with increasing AOD, indicating an "ice crystal suppression effect."
• Partial correlations between AOD and cloud properties remain significant even after controlling for 14 meteorological variables, suggesting aerosol influence independent of meteorological conditions.
• Humidity and wind speed at different altitudes are identified as key modulating factors.

Contributions

• Highlights the importance of accounting for cloud-type differences, moisture conditions, and dynamic processes when assessing aerosol–cloud–climate interactions.
• Provides observational insights to improve the parameterization of aerosol indirect effects in climate models.
