The current weather data is gathered from thousands of professionally installed and maintained weather stations installed mostly at airports. 3D Earth only shows current weather from stations that have reported local weather conditions within the past hour. Current weather data is refreshed every 30 minutes; that is twice as frequent as most other weather providers can offer. Unique 48-hour forecasts from over 80,000 locations around the world provide a level of coverage and detail that simply cannot be found elsewhere.
