Harvard Forest Climate Data since 1964

This dataset provides daily air temperature and precipitation data from Harvard Forest for long-term climate studies. It combines measurements from the original manual weather station (Shaler, 1964-2002, dataset HF000) with measurements from the current automated weather station (Fisher, since 2001, dataset HF001). Gaps in the Shaler data were filled using data from nearby stations. Data from a 12-month period when both stations were operational were used to adjust the Shaler data to more closely match the Fisher data. This dataset is updated annually.
