Summary
From 26 March to 22 April 2003, Germany and Finland carried out a joint expedition (ABSIS - Arctic Atmospheric Boundary Layer and Sea Ice Interaction Study) to test and improve the description of the ocean-ice-atmosphere interaction processes. ABSIS was part of the German ACSYS (Arctic Climate System Study) contribution supported by the Ministry of Education and Research and was connected with the RV Polarstern Winter Arctic Polynia Study expedition. The main objectives of ABSIS were to collect data sets to quantify and study: (a) the thermodynamic and dynamic interaction processes at the ice-atmosphere interface and (b) the vertical structure of the atmospheric boundary layer, particularly the Arctic inversion. The latter is a nearly permanent feature over the sea ice. The Arctic inversion is particularly low and strong in winter and effects the exchange between the boundary layer and the free atmosphere as well as the interaction processes at the ice surface.

To achieve the above-mentioned objectives various platforms were applied and placed within a 200 km2 area north of Spitsbergen during the expedition period 26 March to 22 April 2003: RV Polarstern and RV Aranda, a research aircraft (Falcon-20 of the German Aerospace Center), 11 automatic ice buoys, and one ice camp station close to RV Polarstern (8-18 April 2003 only).

In addition to the published datasets several other measurements were performed during the experiment. Corresonding datasets will be published in the near future and are available on request.
Details about all used platforms and sensors and all performed measurements are listed in the fieldreport.
The following datasets are available on request: ground data at RV Aranda, ground data at RV Polarstern, ice station near RV Polarstern

Description
observation: Level2c
All presented data is observational. Accuracy and precision are dependent on sensors and platforms. Details to sensor types, error sources and quality checking are given in Additional Information accompanying each dataset.;All datasets passed several quality checks. Quality control took place during the field phase; data were controlled during their use for research and and again before publishing.
Data were processed with objective algorithms (e.g. to reject values out of range) and were controlled subjectively by experienced researchers. The processing is described in detail in the documentation of each dataset.
In addition the buoy dataset contains unprocessed raw data files as provided by ARGOS.
