Abstract:

Precipitation has been measured using rain gauges located in or around each watershed since 1956. Three types of rain gauges have been used: standard, mechanical weight recording, and electronic weight recording. Between 1956 and 2014, precipitation was measured weekly at standard gages located at 24 stations in or near gaged watersheds and at the headquarters building. Weight-recording gages were located at 7 of the 24 stations and capture a continuous strip-chart record. Weekly totals were prorated using daily totals from the nearest recording gage. Beginning in 2011, electronic weighing rain gauges began being implemented to measure 15-minute precipitation. The number of precipitation stations was reduced to 10, when each station was fully converted to an electronic gauge for measuring 15-minute and daily precipitation beginning in 2015 (Green et al. 2018).

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.

SAMPLING DESIGN

Between 1956 and 2014, precipitation was measured at Hubbard Brook by a network of 7 weighing recording rain gages (RRG) and 24 standard rain gauges (SRG). During winter months (Nov-Mar) all gauges were charged with antifreeze and operated with funnels removed. All rain gauges were in clearings maintained to uniform standards with all trees beyond a 40-degree angle measured from the base of the rain gauge removed. Each rain gauge was equipped with Altar windshields to reduce wind effects. Rain gauges were mounted on stands at least 4 feet above the ground to avoid being buried by snow in the winter.

The analog charts on the recording rain gauges were changed approximately weekly, at which time the accumulation in the standard gages was measured. The daily recording rain gage data and weekly standard rain gage data were entered into the computer. Missing data were filled by estimation from other nearby gages. A computer program used the recording rain gage data to prorate the standard rain gage data into daily amounts. The final standard rain gage data are reported here.

Beginning in 2011, electronic weighing rain gauges began being phased into operations for measuring 15-minute precipitation. In 2015, daily precipitation was summed at only 10 sites, which were instrumented with electronic gauges. All other sites were discontinued.

PRECIPITATION COLLECTOR DISTRIBUTION

Standard rain gages were located in the watersheds as follows:

Watershed 1: SRG 1, 2, 3

Watershed 2: SRG 18 (1986-1975)

Watershed 3: SRG 4, 5

Watershed 4: SRG 6, 7, 8
