Overview
The Troll Integrated Cloud Observatory (ICO), part of the Troll Observing Network in Dronning Maud Land, Antarctica, combines advanced remote sensing instruments—cloud radar, depolarization lidar, microwave radiometer, and radiosonde launcher— associated with a micrormeteorological monitoring system. These coordinated measurements provide new insight into the microclimate of the Antarctic ice shelf, where stable boundary layers, katabatic winds, and frequent cloud–surface interactions control the exchange of energy and mass. ICO data are essential for understanding how clouds shape the surface energy and mass budgets, improving climate models, and supporting satellite validation, and are openly available to the research community.
The data set published here is a cloud properties and atmospheric profile data set processed and published through the Finish Meteorological Institute’s CloudNet service. Data begin in Feb 2025 and are continuously updated.
