What does this program measure?
A Global Positioning System (GPS) reference station at Mauna Loa facility is used to derive column water vapor profiles.
How does this program work?
The system operates continuously and remotely. GPS data is communicated to Stanford University in real time.
Why is this research important?
The primary interest is to prototype the development of a high integrity wide area differential GPS correction service for aviation use. Key issues include geographic separation of Hawaii from CONUS, the ionosphere at low altitudes, and the troposphere at high altitudes.
Are there any trends in the data?
How does this program fit into the big picture?
What is it's role in global climate change?
