4/10/2017 Boise State University, Dept of Geosciences, Hydrologic Sciences, Jim McNamara Research Director, Pam Aishlin Data Management Data provided herein is for the Lower Weather catchment of Dry Creek Experimental Watershed, Boise, Idaho. DATA STREAM: 1. Two pits, pit 1 and pit 2, were emplaced jointly by Boise State University and NW region Agricultural Resource, USDA, of Boise, Idaho, 1998, in conjunction with weather station installation at this site in 1998. Within each of these two pits, Campbell Scientific CS615 Water Content sensors were installed at 5 depths. Sensor depths vary by pit. A thermocouple is installed alongside each CS615 to provide same point soil temperature. 2. Data collection and site maintenance is provided by Boise State University Hydrologic Sciences. Data collection for Pit3 and 4 began 5/6/1999, associated with the Lower weather station. 3. Data files collected via Campbell Scientific datalogger are quality checked and post processed for gapfilling, noise filtering and/or corrected according to established instrument calibrations. Calibration documents are identified as BSU archive files M:\boisefront\products\historical\dcew_lw\Soil Data ....dchandle\MyDocuments\reports and publications\WCR note\[Low_Up_Trase_CS615_data!.xls] as well as http://www.ictinternational.com.au/reftrase.htm http://adattar.atestor.hu:81/epito/talaj_nedvesseg_analizator.pdf Calibration is based upon Trase (tm) Soil Water Content values plotted against CS615 period values for each sensor. Field based calibration was conducted on 22 separate days during years 1999 through 2001, across all seasons. DATA/INSTRUMENT NOTES: Pit 1 is located south of pit 2 with 5 meters lateral separation, on the north facing slope adjacent to the Lower weather station. Site data files contain multiple fields, one field (column) for each sensor at a given depth and pit location. TL soil data is provided at hourly increments. Soil pits 1 and 2 include both soil moisture and soil temperature at the following depths, in centimeters. Pit 1: 5,15,30,50,100; Pit 2: 5,15,30,60,100 Bedrock in this catchment varies, from zero to approximately one meter. Sandy loam over fractured granodiorite.

ERRORS/GAPS/UPDATES: 2004-2011 2012 2013 2014 2015 gaps occur in June, numerous gaps fall 2015. soil moi sensor at Pit 2 100 cm fails fall 2015. Pit 1 100 cm soil moi performs poorly. 2016 same sensor failures. 2017 same sensor failures. Additionally, Pit 2 30 cm T sensor has failed. 2018 same sensor failures. gap 9/28 1400. 2019 same sensor failures. Gap in heatflux data 4/26 - 7/1/2019. 2020 same sensor failures. gaps occur 8/8/20 and 12/18 - 12/19/2020. 2021 sensor failures as above and additional: moisture pit 1 30, 50 and 100 cm. pit 2 60 cm. Pit 2 30 cm T sensor has failed.
