Received a email from Radarbox today.
AirNav Systems is pleased to announce the release of a new Raspberry Pi build (software update) for feeders sharing data with RadarBox.com. The new build (v0.4.2) allows for weather data to be collected from the ADS-B data sent by your Raspberry Pi.
The weather data that is collected from your Raspberry Pi ADS-B data includes:
- Air Temperature
- Wind Speed
- Wind Direction
Once collected, the weather data is then processed and used to build and improve the RadarBox Global Weather Model.
I’m surprised how they extract air temperature data from ADS-B data.
If it is clear to me at wind speed that they are using relative ( airspeed indicator) and absolute speed (GPS), then how can the temperature be calculated from the air pressure?
