100 Year History: Temperature

Sources:

• 1892-1942 (Milham, W. I., 1950, Meteorology and meteorological observations in Williams College, also at Hopkins Memorial Experimental Forest and in North Adams: McClelland Press, Williamstown, 40 p.)
• 1942-49 (Milham and North Adams, unpublished Engineering Department data)
• 1950 (NOAA record at Adams, Ma)
• 1951-1982 (NOAA record from Readsboro, Vt, corrected to the elevation of Williamstown using a lapse rate of 3.5° F/1000 feet);
• 1982-present (Hopkins Memorial Forest, Station 1; elevation 885′ (270 m)).

Milham also reports data from 1816-1891 for Williamstown, but records are less complete and are not included here.
