What does this program measure?

The Bromine Oxide (BrO) monitor measures the zenith skylight between 340 and 390 nm. This instrument is also used to monitor Chlorine Dioxide (OCLO).


How does this program work?

Shown Below, the Nitrogen Dioxide and Bromine Oxide sensor covers on the Mauna Loa Sun Deck, where solar radiation is measured.

Why is this research important?

In order to carry out continuous monitoring of BrO at MLO.


Are there any trends in the data?
