Measurements at the Mauna Loa Observatory stopped after the 2022 eruption of the Mauna Loa volcano, when lava flow crossed the access road and took out power lines to the facility. The observatory remains inaccessible by vehicle and without power from the local utility company.

Observatory staff has established limited solar power in four observatory buildings and restored approximately 33 percent of the measurements onsite, including the Global Monitoring Laboratory and Scripps critical CO2 records and other atmospheric measurements.

What does this program measure?


How does this program work?

A modified URG-9000A automated sampler for the collection of semi-continuous ambient samples for analysis of major ions using ion chromatography is used at MLO


Why is this research important?

The objective is to provide collection and analysis of one year of high-resolution (~hourly) atmospheric gas and particulate phase halide samples.


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?
