Summary & Purpose
Paired-aspect monitoring sites in Dry Creek Experimental Watershed, SW Idaho, provide soil moisture and temperature data from four soil pits per each of eight sites. For elevation scaling, the four aspect-paired sites are located at apprx 1130, 1290, 1460, 1820 meters above MSL, spanning grass-shrub to forested environments within steeply sloped terrain. Data sets published here span 2008-current and will extend through 2018 as these data become available. The eight sites and locations in LAT/LONG are:
HN (High N-Facing) 43.74067, -116.118596
HS (High S-Facing) 43.73908, -116.115775
LN (Low N-Facing) 43.68925, -116.169689
LS (Low S-Facing) 43.69082, -116.169382
MHN (Mid-High N-Facing) 43.71715, -116.125309
MHS (Mid-High S-Facing) 43.7205, -116.125744
MLN (Mid-Low N-Facing) 43.70151, -116.148459
MLS (Mid-Low S-Facing) 43.70494, -116.149738

Single Dataset or Series?
Each of the eight sites includes four soil pits with sensors at multiple depths, 2, 15, 30 cm and near bedrock, generally less than one meter. Pits are located at 3 m quadrilateral separation. Sites with shallow soil have fewer sensors. Geology at this location is sandy loam over fractured granodiorite. 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 specifications for sandy loam soil. Post processing includes removal of obvious noise, failed sensors, out-of-range values and data gaps filled with -6999. For some periods, negative soil moisture values are retained to show trends in soil moisture. Raw data is available upon request. Additional pits were installed at sites HS and MHN, 2013, data available upon request. Attribute names (column headings) are defined at the top of each data file.
