More than two years after road access and electrical power to the Mauna Loa Observatory was cut off by lava flows, NOAA staff continue to make critical measurements of the atmosphere and other environmental variables at the remote site.
In 2023, observatory staff installed solar panels at the site and resumed some measurements, including the independent carbon dioxide monitoring programs run by the Global Monitoring Laboratory and Scripps Institution of Oceanography, as well as other atmospheric measurements.
Construction of a temporary road to access the observatory site is anticipated to begin in summer 2025.

What does this program measure?
Total Atmospheric Water Vapor
How does this program work?
The dual frequency GPS receiver will continuously observe all satellites in view. Dual frequency carrier phase observations will be made very 30 seconds. Data will be transferred to the PC every 30 minutes. Quick-look displays will be created by Forecast Systems Laboratory (FSL) and will be available via the internet.
Why is this research important?
Global Positioning System Meteorology gives us the ability to measure the total quantity of water vapor in the atmosphere with unprecedented accuracy under all weather conditions. By continuously monitoring the ratio of integrated precipitable water vapor (IPW) at MLO to three nearby stations at or near sea level, we can evaluate short and long-term changes in the mean temperature of the atmosphere above 600 h Pa.
Are there any trends in the data?
