Cambridge Monthly Weather Graphs

Monthly graphical summaries of the weather data recorded from sensors on the roof of the main AT&T lab building in Cambridge are available from the links below. The graphs are largely self-explanatory, but for details, look here. Historical weather data is also available in daily textual form and as annual and monthly summary statistics.

Note that there are some inaccuracies in the historical humidity and dewpoint readings before October 1998, in the rainfall readings for July and August 2001 and from time to time throughout 2005, and in several readings in July 2006.
