05/15/13, Boise State University, Dept of Geosciences, Hydrologic Sciences, Jim McNamara Research Director, Pam Aishlin Site Maintenance and Data Management Data provided herein is for soil instrumentatin site MHN (mid-high elevation, north-facing) of Dry Creek Experimental Watershed, Boise, Idaho. DATA STREAM: 1. Four pits were emplaced by graduate student Toni Smith, Boise State University in 2007. 2. Data collection and site maintenance is provided by Boise State University Hydrologic Sciences. 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. SITE NOTES: Soil moisture and soil temperature measurement site. Site includes four soil pits with sensors at multiple depths, 2, 15, 30 cm and near bedrock. Pits are located at 3 m quadrilateral separation. Bedrock sensor depths for pits 1-4, accordingly, are 71,97,52,74 cm though bedrock depth is indicated as 90,116,77,85 accordingly. This site is north-facing, located in the Shingle Creek catchment of DCEW. It is one of 8 soil sites established as north-south facing paired sites in 2007, 2008. Geology at this location is Sandy loam over fractured granodiorite. Site is forested and moderately steep. DATA/INSTRUMENT NOTES: Sensors initially installed are Decagon ECH2O EC-TM soil moisture and soil temperature sensors. Sensor precision is 0.001 for volumetric water content (cm3/mc3) and 0.1 celsius for soil temperature. Sensors were calibrated in-lab at Boise State University by Toni Smith, in cooperation with Decagon technical support, in accordance with manual specifications and expected sandy loam soil. An appropriate datalogger program was written by Toni Smith in collaboration with Decagon technical support. An ultrasonic snow depth sensor was installed fall 2012. Additional pits were installed, one upslope and one downslope, 2012, of the above, using Stevens soil sensors, Hydraprobe II. MHNup pit and lower pit have 71,61cm, bedrock depths, respectively. Sensors emplaced at 2, 15, 30 cm and bedrock. This data is available upon request. Stevens soil sensor data is primarily collected as basic data.

Algorithms are used to remove obviously erroneous values, such as negative moisture values and temperature above expected range of -10 to 40 celsius, as well as obviously 'stuck' values. In some years, these algorithms were not applied in order to preserve trends such as occur with soil moisture into the negative range due to sensor calibration offset. ANNUAL ERRORS/GAPS/UPDATES: Data collection initiated April 4, 2008, initially 10 minute data. 2012 - There remain many unworking sensors, as of 4/12/12 only 6 working sensors of 16. Intermittent gaps possible due to power issues early 2012. Data gap 032912 to 041012 due to bear attack onsite. 4/28/12 further work on-site. 052012 to 091212, solar charging is inadequate. 091912 Turned solar panel around, installed usd and new program. Numerous gaps since October have been filled, incl 8/5-8/18/12, 9/6/12 2100 - 9/18/12 1150, minor gap 10/12/12 1500. changed to 15 min data 10/12/12 1500. Minor gap 10/19/12 1615, minor gap 10/26 1300 - 1600, 11/3/12 solar wired chewed. gaps 11/1-11/25, 12/6,9, gap 12/23/12-12/29/12, load disconnect. 10/20/12 emplacing two new soil pits, Stevens sensors. 2013 - Changed from 15 min to hrly data 4/1/2013. 2014 - No gaps. 2015- Original pit sensors installed remain largely failed with 6 working soil mois sensors (of 16) and 5 working temp sensors. Fall 2015, the upper pit #7 Stevens 30 cm sensor failed. 2016- As above, original 'Echo' sensors above remained failed. Lower pit Stevens deepest soil moi sensor failed end of Jy, 2016, T value initially 'stuck', then shifts to nodata value in 2017. 2017 - pit 4 15 cm Temp sensor outputs obviously erroneous and/or suspect values, therefore replaced by -6999 no data values, pit 4 15 cm moisture sensor data is noisy, suspect. Stevens sensor #6, upper pit 30 cm becomes the second sensor in this pit to fail, w/ T value 'stuck' while soil moi fails. 6/23/17 sensor #5, 5 cm, fails, resulting in 3 of 4 sensors failed in the upper pit. Sensor 5 is again operational 10/24/17. 6/23/2017 Apparently, a bear, had chewed antenna cable and pulled it out of the box, disconnecting the radio. Also pushed dl box down a little. Repaired. Tightened guying to solar panel. Bear tree had fallen, 4 ft away from box. Repaired shield wires to AG on mux for 'Echo' sensor #’s 3,16,14,10. 10/24/2017 Stevens sensors - no evidence of damage to new soil sensors. Took photos. Wiring remains intact.
