The meteorological diary of Dr. Edward A. Holyoke from Salem (Ma. USA) is published by E. Hale (1833) A Meteorological Journal from the Year 1786 to the Year 1829, inclusive, by Edward A. Holyoke, M.D., A.A.S., Mem. Amer. Acad. Arts Sci. 1:107-216. The digitized data are taken from this publication.
The digitization and homogenization of the data is reported by van der Schrier and Jones (2008a). Please refer to this study for details regarding Dr. Holyoke, the position of the instruments in his house and the adjustments made to the data. Please cite this study when using this data.
A follow-up to this study is van der Schrier and Jones (2008b).

Description of the data The files holyoke.partI.dat and holyoke.partII.dat contain pressure and thermometer readings from the years 1786-1820 (partI) and thermometer readings from 1821-1829 (partII). The third file contains the description of the weather spanning the period 1786-1829. These datafiles reflect the data originally published by Hale (1833). The files holyoke.pressure.dat and holyoke.temperature.dat contain the Holyoke data, but adjusted using a homogenization method and converted to modern units. The format, units and missing values used of the data is explained in the readme file. The observation time for the first measurement was generally noted down as `eight o'clock', but sometimes `from eight to nine'. The second observation (for temperature and the state of the weather) is generally made around noon, but sometimes `at one P.M.', `at two P.M.' or `between one and two P.M.'. The third measurement (for temperature and the state of the weather) is at sunset, and the fourth is uniformly at ten in the evening. |
This is the readme file attached to the digitized data from the meteorological diary of prof. Edward Wigglesworth, Cambridge (Ma., USA). The Wigglesworth data are digitized from photographs of Wigglesworth's original handwritten meteorological diary. The photographs are in the collection of files from prof. Hubert Lamb of the Climatic Research Unit and were presumably ordered for his SLP reconstruction (Lamb and Johnson 1959).
The digitization of the data is reported by van der Schrier and Jones (2008a) Please refer to this study for details regarding Prof. Wigglesworth and his meteorological diary. Please cite this study when using this data.

Description of the data The file wigglesworth.introduction.txt contains a transcription of the introduction Wigglesworth wrote in his meteorological diary. This contains metadata on positions etc. of the instruments. Quite a few words were illegible on these photographs, which resulted in many "?" for each word I could not decipher. The files wigglesworth.pressure.dat and wigglesworth.temperature.dat contain pressure and temperature records respectively, converted to modern units. The format, units and missing values used of the data is explained in the readme file.
