High Altitude Amateur-Radio.

Tracking upper air sounding is our passion.

Welcome to OpenWX.de

Early automated upper-air sounding systems were using RDF wind finding and were able to track qualified radiosondes from multiple manufacturers.
Radio amateurs all over the world have been working on  radiosonde decoding possible by free & open source software. OpenWX.de is visualizing free radiosonde monitoring data for non-commercial purposes.

Explore radio soundings ... 

Are you already monitoring radio sonde soundings with an SDR RX and dxlAPRS, the state-of-the art software solution provided by Chris, OE5DXL? Become part of OpenWX.de, setup your gateway and sign-in to our OpenWX weather information network.

Some Feature Highligths ...

We are a small crew of enthusiast radio amateurs. We started in 2010 launching our first amateur radio high altitude balloon (Project HAAROB).
 
Over many years and our next balloon launches
we were working on free tools for decoding, prediction and visualization solutions.

In 2019 we decided to start with the mapping and gateway network focussed on top functionality and providing more top features in OpenWX monitoring.

Statistics Dashboard

A real highlight is our statistics dashboard based on a seperate database providing several data for all our RX-gateways to check and optimize your station.

Database Search

Looking for a specific launch you can use OpenWX Archive to search for specific soundings by date, launch site or the radiosonde ID.

Mobile Template

On the track we do not only want responsive design, we developed a stunning mobile template with all important details at a glance.

Browser Compatibility

Use your favorite desktop, tablet or mobile browser. Depending on your device you may like visualization in Apple Maps, Google Maps our Apps like Locus Pro.
