What is SWoS?

A video showcasing SWoS's capabilities of nowcasting rain.

SWoS, the Shanghai Weather Warning and Observation System, unifies precipitation nowcasting, forecasting, typhoon route monitoring and inter-comparison between meteorological agencies, weather warnings, etc. In a single pane of glass.

It is under very active development currently (as of October 2025). Unfortunately, SWoS is not currently publicly hosted due to licensing issues. However, the project has been open-sourced and you can self-host it!
