Cloud computing and RO data in the AWS Open Data Registry Side-workshop (S. Leroy)

GNSS RO has arrived in the Amazon Web Services (AWS) Open Data Registry for free download.
This workshop will introduce the world of AWS cloud computing at the level of an IROWG participant.
The only prerequisites are a laptop computer with ssh installed. Some experience in scientific programming in Python would help.
