Abstract: The surface temperature and sea ice data resides in 26 books, 'Eisbericht Amtsblatt Des Deutschen Hydrographischen Instituts' (C/dc 100 Ae) written in German. The data contained in these books are daily observations of surface temperature and ice and navigation conditions for coastal stations in Scandinavia, USSR, Germany, Netherlands, North Sea, and Baltic Sea. These data are for each day of the ... period 1901 to 1977. Some data are missing from 1970 to 1972. The temperature parameters included in these observations are the following: sea surface temperature (including deviation from the mean), and the air temperature.
The surface weather data resides in 21 books, 'Maanedsoversight Over Vejrforholdene (c/daa AO-ma) written in Dutch. In these summaries, definitions are:
1. Daily/monthly/seasonal/annual data - values determined for each consecutive period, e.g., monthly temperature data: Jan 1900, Feb 1900, Mar 1900, etc.
2. Long-term data - values determined over a period of years, e.g., long-term monthly temperature data using Jan 1901, Jan 1902, Jan 1903, etc.
The data contained in these books are tables of hourly, daily, and monthly surface temperature, humidity, wind, pressure and precipitation as well as maps of monthly temperature and precipitation for Denmark and Sweden. These data are for each month of the period 1914 to 1956. The tables contain the following data: hourly temperature and humidity; daily maximum and minimum air temperature; daily rainfall totals; monthly mean pressure, temperature, and humidity; absolute monthly maximum and minimum temperature; monthly rainfall totals; monthly 24 hour maximum rainfall; and monthly number of days of rain, snow, hail, thunderstorms, calm winds, and frost. Monthly normals for each of the parameters are also given. The maps contain monthly mean temperature, monthly rainfall totals, monthly maximum and minimum air temperature.
These books are part of the foreign meteorological data collection held by the NOAA Central Library in Washington, DC. Information in this collection dates back to the 18th century for daily, monthly, seasonal, and annual tabular summaries, and the 19th century for weather maps. These data are the result of foreign exchange agreements, but the collection has not been updated since 1983.
