  • Abstract:

    In recent years the Harvard Forest has developed a complementary suite of long-term, continuous measurements to support detailed studies of water budgets for small forested watersheds on the Prospect Hill Tract. Measurement stations include:

    1. The Fisher Meteorological Station (since 2001), located in an open field next to the Harvard Forest headquarters, measures air temperature, relative humidity, dew point, precipitation, solar radiation, PAR radiation, net radiation, wind speed, wind direction, gust speed, and soil temperature. The Met Station is a node on the field wireless network. Measured values and graphs of selected data are updated on the HF website every 15 minutes (dataset HF001).

    2. Hydrological gages on the Prospect Hill Tract (since 2007-08) measure surface discharge and water temperature of two small headwater streams, Nelson Brook (Millers River watershed) and Bigelow Brook (Swift River watershed), as well as water level and water temperature in two large associated wetlands (Black Gum Swamp and Beaver Swamp). Fifteen-minute data are collected every 1-2 weeks and posted on the HF website (dataset HF070).

    3. The Harvard Forest Snow Pillow (since 2009) measures water content of snowpack (snow water equivalent) during the winter months. The snow pillow is located in a mature mixed hardwood stand with scattered conifers about 50 m north of the Nelson Brook Big Weir. Fifteen-minute data are collected every 1-2 weeks in winter and posted on the HF website (dataset HF155).

    In 2013 line power was extended to the hydrological gages and snow pillow in conjunction with electrical upgrades for the new NEON tower and aquatic site. Plans for 2014 include adding the hydrological gages and snow pillow to the field wireless network to support near-real time data collection and posting to the HF website.
