Here’s an update on this. Tempest data is already provided directly to NOAA and other government meteorological agencies through the US National Mesonet Program via Synoptic Data. Synoptic is actually the commercial side of MesoWest (more accurately, MesoWest is now also known as “Synoptic Labs”).
So, this means that as long as your Tempest is reporting data online, WeatherFlow is doing the legwork to share the data to all government agencies and there’s no need to share it separately through CWOP. In fact, sending data to CWOP through a third-party device like weewx or meteobridge can actually create an issue with duplicate data in systems that receive both.
