Welcome to Satellite Meteorology Laboratory at Pusan National University!

 Our research group aims to improve the accuracy of satellite observations and enhance our understanding of weather and climate phenomena using these observations. 

More specifically, our research focuses on understanding the microphysical characteristics of global precipitating clouds and improving the accuracy of satellite precipitation estimates. 

We also seek to expand satellite-based research into broader areas using artificial intelligence (AI) and machine learning (ML). 

Our main research thrusts using satellite observation data are:

Global analysis of precipitating clouds

• Extreme rainfall/snowfall clouds

• Cloud characteristics of tropical cyclone, extratropical cyclone, atmospheric river, etc.

• Fusion analysis using satellite observation and reanalysis data

Research using spaceborne radar

• Evaluation of precipitation estimates from passive microwave (PMW) sensors using GPM observation

• Cloud vertical structure (GPM DPR, EarthCARE, ...)

• Microphysical characteristics (drop size distribution)

AI/ML based research

• Adjustment of precipitation estimates among PMW sensors using super-resolution approach

• Inter-satellite product extension
