FRONTEX 1989 - Atmospheric Fronts in the Coastal Area of Northern Germany


Jeske, Helmut; Brümmer, Burghard; Wetzel, Christian

The field experiment FRONTEX 1989 (FRONT EXperiment) took place in the German coastal area of the North Sea between 2 May and 6 June 1989. It was coordinated by the Meteorological Institute of the University of Hamburg and was primarily funded by the German Research Foundation (DFG) in the frame of the priority programme "Fronten und Orographie".

The scientific aim was the investigation of cold fronts moving in from the North Sea and reaching the coastal area. The different physical properties of sea and land surface (roughness, humidity, temperature, heat conduction and heat capacity) modify the frontal structure at landfall. The modification should first alter the boundary layer and is then communicated to higher levels, thus effects like convection and convergence will be found farther inland.

The experimental concept was to monitor the passing front on all relevant temporal and spatial scales. To obtain this goal a large variety of measurement platforms was employed. Ground based remote sensing and in-situ measurements were performed at Heligoland, Schleswig, Hanover, Emden, Berlin, and on board the research vessel. Three research aircraft (POLAR-2 and POLAR-4 of AWI Bremerhaven and DO-128 of TU Braunschweig) were used to measure the frontal structure with high temporal and spatial resolution.

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.
Data acquisition is completed.
