MAIDO Observatory

The Maido observatory on Reunion island is located in the southern Indian Ocean, at an altitude of 2km. It is an ideal location to probe the pristine free troposphere in the southern hemisphere. While aircraft measurements are snapshots in time, the Maido observatory allows the acquisition of longer time series and investigation of diurnal cycles. Measurements at the Maido observatory are complemented with measurements at sea level.

During the intensive operating period early 2018 a comprehensive suit of instruments acquires data on particle composition, formation, and growth, and abundance and profiles of trace gases. CU Boulder deploys a CE-DOAS instrument for first measurements of glyoxal diurnal cycles in the free troposphere and a MAX-DOAS instrument for the altitude resolved detection of halogens.
