  • Abstract:

    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.

  • Methods:

    Gaps in the Shaler data were filled using daily data from Amherst MA and Bedford MA downloaded from the National Climatic Data Center. Overlap data when the Shaler and Fisher stations were both operational (2001-07-01 to 2002-06-30) were used to adjust the Shaler data to more closely match the Fisher data. Because daily observation periods were not the same across stations, gap filling and adjustments were based on comparisons of mean air temperature and total precipitation over the entire observation period. Details of the analysis may be found the R scripts.
