Radio Occultation Experiment - Installation and Data Management: 

Measure atmospheric humidity up to 100km away from the Perlan II glider using GPS satellite navigation signals. Water in the upper atmosphere where Perlan flies is the number one greenhouse gas and has a significant impact on global weather. Radio occultation has been found to be one of the most efficient measurement techniques to reduce weather forecast errors. 

The GPS- Radio Occultation instrument tracks GPS satellites close to the horizon and over the horizon, and by observing changes to the highly accurate GPS navigation signals, measures the humidity in the atmosphere up to 100km away from the aircraft on which it is mounted. In the long term, GPS-RO may become a standard feature on airliners to enhance weather predictions in the regions that airliners fly.

This radio occultation experiment will demonstrate how this lightweight technology can be easily carried on aircraft flying around the world and contribute meaningfully to scalable forecast improvements.

The Perlan Project possesses 2-pound GNSS-RO device that has the potential to scale into aircraft around the world. The device needs to be installed on the perlan2 and a research plan fully developed. 

Investment needed for installation and data management: $5,000
