How does it work?

The basic idea is very simple. Set up a weather station on the mountain top. Weather station checks the weather (wind, temperature) every 5 or 10 minutes and reports the conditions over a radio link to the club house or other places.

We use low-power medium-range data communication equipment, so maximum distance is about 4-5 kilometers and the direct line of sight is required. 4-5 kilometers is not really that far, but most club-houses fall within this range and we have to conserve the battery power. If you need the extra range, there's a high power option available.

If your place is hidden behind the mountain, you probably won't be able to receive current weather.

Because wind conditions are measured every few minutes (not every hour, like most other weather services), we can really see the dynamics of the wind change and even estimate the thermic conditions. For example, if the wind reads 1-4-2-3-4-1-2, it's possible that real wind speed is about 2.5m/s and there are strong thermals about +2m/s coming from time to time.
