Participant Ballooning Resources

New to high altitude ballooning?


Below you will find resources to help you find suitable launch sites:

  • Cloud Cover: Anticipate the likelihood of clouds for your preferred launch site.
  • This aeronautical map may prove useful.
  • Get Google Earth
  • 2017 Eclipse Participant Overlay (kmz): Pre-made Google Earth kmz file containing eclipse overlay, aviation and airspace overlays, current event participant launch locations and predictions for those locations. This is a great starting place to determine launch site suitability. Please click here for any questions on how to to choose an appropriate launch site. *NOTE* If all overlays are “clicked on” Google Earth may run sluggishly.
  • Google Earth Eclipse Overlay: Eclipse overlay kmz files for Google Earth.
  • Restricted Airspace Overlay: *Note* This does not include Military Operations Areas (MOAs) or other restricted areas possessing altitude restrictions
  • State Land Status Overlays: Download Google Earth Land Status overlays for individual states (National Park Service land, National Forest Service land, etc.).
  • USGS Topographic Overlay for Google Earth: Topographic overlay for Google Earth to help determine landing site terrain.
  • Predict HAB Hub: Online balloon prediction software. KML and KMZ export are both supported. Please note, we do not recommend using this resource as a “calculator” for calculating balloon fill amount.
  • Balloon Prediction Software: Download Jordan Allen’s Balloon Prediction Software to make your own launch site predictions. Once the software is installed, enter your site lat/lon/alt, choose one of the “bursting” rise rate defaults, choose a time and press a “make prediction” button. Jordan Allen prefers GFS Model predictions these days for accuracy and time coverage, and the ability to forecast up to a week ahead. Disclaimer: The availability of this tool to the general public does not condone attempts to recover balloon payloads that land on private property, government property, or hazardous locations. Predicted trajectories and landing zones are only approximate, therefore active tracking is required to accurately locate launched payloads. These predictions can be exported as kml files which can then be imported into Google Earth.
