Our network of sensors means more data. More data means better forecasts when it matters most. While everyone benefits from better data, sensor owners enjoy:

  • Precision: Get weather conditions for your exact location (not your neighbor’s or at the airport)
  • Visualization: See comprehensive dashboards and graphs of your station data
  • Historical: Archive your historical data so you can always look back
  • Share: Share your data and help us improve weather forecasting for everyone

Our mission is to make the highest quality weather information available to every person on this planet. Join our global community and help us improve weather forecasting.
