Measurements at NOAA's Mauna Loa Observatory stopped following the recent eruption of the Mauna Loa volcano, when lava flow blocked staff access and took out power lines to the facility.

Under an emergency agreement, NOAA and the University of Hawaii have established a temporary measurement site at the nearby Mauna Kea volcano for the critical CO2 record and other atmospheric measurements taken at the observatory.

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?
