Abstract: The German data resides in 3 books, 'Ergebnisse Der Meteorologischen Beobachtungen in Systeme Fur Das Lustrum' (C/dc 100 A3) written in German. 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 this book are tables of monthly climatic data for Coastal Western Germany, Poland, and Lithuania from 1886-1895. The tables contain the following data: long-term monthly mean maximum and minimum pressure; long-term monthly mean maximum and minimum temperature; long-term monthly mean monthly relative humidity; long-term monthly mean monthly rainfall; long-term monthly mean cloudiness; long-term monthly number of days of snow, thunderstorms, clear skies, cloudy skies, etc.; and long-term monthly wind direction frequency.
Additional German data resides in 1 book, 'Vergleighende Untersuchungen Klimate Von Freiburg 1. Br. Und Rom' (C/dc 151 F837) written in German. In these summaries, definitions are as in the above. The data contained in this book are tables of monthly climate data for Germany determined for the period 1886 to 1910. The tables contain the following data: monthly mean temperature, humidity, precipitation, cloudiness, and pressure; monthly mean maximum and minimum precipitation; monthly maximum precipitation in 24 hours; monthly absolute maximum and minimum temperature; monthly total number of days of snow; monthly mean number of days of snow, precipitation, and fog; monthly wind direction frequency; seasonal mean hail and thunderstorm days; seasonal mean precipitation; annual mean hail and thunderstorm days; and annual mean 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.
