Abstract:

Throughfall and precipitation data at Watershed 3 (Rain guage 4) 2006-2008.

These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.

Description:

METHOD DESCRIPTION

Throughfall and precipitation volumes were monitored biweekly throughout the year as part of a water isotope study (Green et al. 2015). Two replicate precipitation collectors were installed adjacent to each other in the clearing for rain guage 4 in watershed 3. Throughfall was collected beneath a northern hardwood forest canopy at six randomly selected locations in an area adjacent to the rain gauge clearing. Precipitaton and throughfall collectors consisted of 15-cm diameter by 50-cm-long PVC pipes lined with polyethylene collection bags. The collectors were mounted on vertical stakes 1.5 m above the ground surface. During winter the snow and ice that accumulated in the bag was brought back to Hubbard Brook headquarters and melted at room temperature before recording the volume. When precipitation fell mostly as rain, a small amount of mineral oil was added to the bags to prevent evaporation and maintain the isotopic composition of the sample. Please note that the collectors did not have wind shields so the measured volumes may be less than the actual volumes. These precipitation values can be compared to the daily precipitation values at rain gauge 4 that are collected as part of the long-term meteorological record.
