Data sets

Long-term in situ (O)VOC measurements at the Maïdo observatory (Reunion Island) Amelynck, C., Schoon, N., and Verreyken, B.

ICOS Atmosphere Level 2 data, La Réunion M. De Mazière, M. K. Sha, and M. Ramonet

Short summary
We present a 2-year dataset of trace gas concentrations, specifically an array of volatile organic compounds (VOCs), recorded at the Maïdo observatory, a remote tropical high-altitude site located on a small island in the southwest Indian Ocean. We found that island-scale transport is an important driver for the daily cycle of VOC concentrations. During the day, surface emissions from the island affect the atmospheric composition at Maïdo greatly, while at night this impact is strongly reduced.
