Swedish Lightship Meteorological and Oceanographic Observations from 1860 to 1989

1860 to 1989 records of wind, air temperature, water temperature, salinity, and current measurements collected once or twice daily at different depths from Swedish lightships and shore stations. The NOAA National Centers for Environmental Information (NCEI) archives this historical dataset, which includes observations from up to 14 lightships primarily during May to November.

Use Cases

• Analyze long-term trends in Baltic Sea water temperature and salinity from the recorded hydrographic parameters.
• Study historical wind patterns and air temperature variability using the meteorological observations.
• Correlate current measurements at different depths with seasonal data from the May-November observation periods.
• Compare environmental conditions across different Swedish coastal stations like Finngrundet, Falsterborev, and Borno.
• Validate climate models using the century-spanning time-series data from 1860 to 1989.

Strengths

• Data spans 129 years from 1860 to 1989, providing a long-term historical record.
• Observations cover multiple parameters: wind, air temperature, water temperature, salinity, and currents.
• Includes data from up to 14 different lightships and several shore stations, offering spatial variety.

Limitations

• Observations were primarily made during May to November, missing full annual coverage.
• Data collection was interrupted during the First and Second World Wars, creating gaps.
• The exact number of rows, measurement frequency, and data completeness for each station are unknown.
