Study of Antarctic blowing snow storms using MODIS and CALIOP observations with a machine learning model ...
As a common phenomenon over Antarctica, blowing snow (BLSN), especially the large BLSN storms, play an important role in the Antarctic surface mass balance, radiation budget and planetary boundary processes. This paper presents the work on BLSN storm identification and analysis with observations fro...

As a common phenomenon over Antarctica, blowing snow (BLSN), especially the large BLSN storms, play an important role in the Antarctic surface mass balance, radiation budget and planetary boundary processes.
