The type of science supported
Monitoring and recording interactions between the Earth’s crust, ice- and snow-covered areas, oceans, and the atmosphere:
Mapping of the Earth’s magnetic and gravity field for tectonic studies
Mapping of ice thickness and internal structures of ice shelves, ice sheets, and glaciers for mass balance studies, input and reference data sets for ice dynamic modelling studies
Mapping of sea ice thickness, snow thickness on sea ice, and surface morphology/altimetry for calibraction and validation of satellite derived remote sensing data
Measuring in-situ and remotely of aerosols and trace gases for process studies and input and reference data sets for modelling studies
Measuring of radiation, temperatures, humidity, and turbulent fluxes for process studies and input and reference data sets for modelling studies of the planetary boundary layer
Optical remote sensing for mapping biodiversity in the Wadden Sea and land cover disturbances related to permafrost thaw
Besides scientific operations, the aircrafts are maintaining logistics between different international research stations in the Antarctic, where the AWI is an active member of the international Dronning Maud Land Air Network (DROMLAN).
The AWI strategy in terms of aircraft in polar regions in the next decade
As in the past, in the forthcoming years AWI aircraft will be operating in Antarctica, as well as in the Arctic in each season. The aircraft will be used for scientific expeditions and for logistic tasks in order to support science. The home base of the aircraft is Bremen Airport. The available instrument suite is constantly expanded to meet the requirements by the science community.
