Meteorological measurements in the Baltic and the North Sea — •Jörg Bendfeld and Stefan Krauter — Universität Paderborn

The standard requirements expressed in the "Guide to Meteorological Instruments and Methods of Observation" (WMO, 1996) are not directly applicable for offshore meteorological stations. For a wind measuring instrument they require a height of 10 m above ground and a distance to the next obstacle which must be at least ten times the height of this obstacle. Meteorological variables affect ecosystems. The magnitude and changes in time of the meteorological variables should be assessed as accurately as possible in order to be able to use the meteorological data as explanatory factors of the many other observations. Geographic features affect airflow and limit the representativity of the meteorological data by spatial heterogeneity (e.g. location, altitude, exposition, slope). Meteorological variables as air temperature, relative humidity, precipitation, wind velocity and direction are important. The design and the measurements are elaborated according to the environmental circumstances.
