You do not even need your own website to share your METAR data around the world. Wunderground.com provides an internationally recognized weather site to post your data live at no charge.
Anyone with a personal weather station supported by Virtual Weather Station, available from Ambient will be able to post their data on the Web, anytime, and without incurring any fee.
All of the Personal Weather Stations are indexed, searchable, and completely accessible
to any site visitor.
Virtual Weather Station users that sign-up will automatically submit
data to the system a minimum of once each hour. Users may also manually select to send updates
as frequently as 15 minutes if they so desire.
Your weather conditions are displayed in the same format as NWS information, and also includes the latest forecast information from the NWS below your stations display.
Weatherforyou.com and Hamweather.com have teamed to provide a powerful networking weather service for personal weather station owners.
To register your weather station as a private weather station, select the Sign-up Your Station button and proceed by registering your weather station at Hamweather.
