BASIS 1998 as well as the field experiments BASIS 2001 and ALKOR 2000 and 2001 are part of the research compound BALTIMOS (BALTic sea Integrated MOdel System). BALTIMOS in turn is part of the Baltic Sea Experiment (BALTEX). The overall objective of all eight field experiments (ALKOR and BASIS) was to collect a comprehensive data set suited to validate the coupled model system BALTIMOS for the Baltic Sea region. The observations mainly focus on: - the atmospheric boundary layer structure and processes and the air-sea-ice interaction over areas with inhomogeneous sea ice cover - the atmospheric boundary layer structure over open water under different synoptic conditions such as cold-air advection, warm-air advection or frontal passages. Observations during BASIS 2001 were made at three land stations and the Finnish research vessel Aranda. All stations performed radiosonde measurements. The German research aircraft Falcon had six flight missions with measurements of meteorological parameters and turbulent fluxes. 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: meteorological stations Kokkola, Umea, Merikarvia, ground data at RV Aranda Prof. Dr. Burghard Brümmer University of Hamburg (MI) http://www.mi.uni-hamburg.de/ author Dr. Gerd Müller University of Hamburg (MI) http://www.mi.uni-hamburg.de/ author Dr. Stefan Thiemann University of Hamburg (MI) http://www.mi.uni-hamburg.de/ author Christian Wetzel University of Hamburg (MI) http://www.mi.uni-hamburg.de/ author Prof. Dr. Burghard Brümmer University of Hamburg (MI) http://www.mi.uni-hamburg.de/ principalInvestigator Dr. Gerd Müller University of Hamburg (MI) http://www.mi.uni-hamburg.de/ pointOfContact aircraft measurement theme observational data theme radiosonde theme ship theme Baltic Sea theme aircraft theme ice theme eng 19.0 23.0 62.0 64.5 1998-02-17 1998-03-06 1 1998-02-18 1998-03-06 1 1998-02-27 1998-03-06 1 1998-02-17 1998-03-06 0 air_pressure modelResult hPa air_pressure modelResult hPa air_pressure modelResult hPa air_pressure_at_sea_level modelResult hPa air_temperature modelResult not filled air_temperature modelResult not filled air_temperature modelResult not filled air_temperature modelResult not filled dew_point_temperature modelResult not filled dew_point_temperature modelResult not filled dew_point_temperature modelResult not filled downwelling_longwave_flux_in_air modelResult W m-2 downwelling_shortwave_flux_in_air modelResult W m-2 eastward_wind modelResult m s-1 height modelResult m height modelResult m height modelResult m height modelResult m humidity_mixing_ratio modelResult g kg-1 latitude modelResult degree_north longitude modelResult degree_east northward_wind modelResult m s-1 relative_humidity modelResult not filled relative_humidity modelResult not filled relative_humidity modelResult not filled specific_humidity modelResult g kg-1 specific_humidity modelResult g kg-1 specific_humidity modelResult g kg-1 surface_temperature modelResult not filled time modelResult s upward_air_velocity modelResult m s-1 upward_latent_heat_flux_in_air modelResult W m-2 upward_sensible_heat_flux_in_air modelResult W m-2 upwelling_longwave_flux_in_air modelResult W m-2 upwelling_shortwave_flux_in_air modelResult W m-2 wind_from_direction modelResult degree wind_from_direction modelResult degree wind_from_direction modelResult degree wind_from_direction modelResult degree wind_speed modelResult m s-1 wind_speed modelResult m s-1 wind_speed modelResult m s-1 wind_speed modelResult m s-1 tar-File(s) tar-File(s) distributor Mb 49 http://doi.org/doi:10.1594/WDCC/UNI_HH_MI_BASIS1998 series
