Southern Sierra Critical Zone Observatory (SSCZO), Providence Creek meteorological data, soil moisture and temperature, snow depth and air temperature
Bales, Roger et al. (2013), Southern Sierra Critical Zone Observatory (SSCZO), Providence Creek meteorological data, soil moisture and temperature, snow depth and air temperature, v2, UC Merced Dash, Dataset, https://doi.org/10.6071/Z7WC73
Snow depth, soil moisture and soil temperature are measured at lower Providence South facing (LowMetS) and North facing (LowMetN), Upper Providence South facing (UpMetS), North facing (UpMetN) and Flat aspect (UpMetF), and Subcatchment basin P301 (P301) with a wireless sensor network, using a Campbell Scientific logger to control peripheral devices. Snow depth is measured in the open, at the drip edge and under canopies. Soil moisture and temperature are measured at 10, 30, 60 and 90 cm depths coincident with the snow depth nodes. 10 watt solar panels provides power for monitoring at 10 minute intervals. Raw data have been processed to level 1 (QA/QC) and level 2 (gap-filled, derived) data. Time period: water year 2008 through water year 2012 (version 1), 2013 to 2016 (version 2).
Soil volumetric water content (VWC) and soil temperature measured using Decagon Devices ECHO-TM at depths of 10, 30, 60, an 90 cm below the mineral soil surface. Sensor now equivalent to 5TM (http://www.decagon.com/soil-moisture-sensors/). Distance to snow/soil surface and air temperature measured with Judd Communications ultrasonic depth sensor, using analog control ( http://www.juddcom.com/ ). Data control and storage on Campbell Scientific CR1000 datalogger, using AM16/32B multiplexer ( http://www.campbellsci.com ). Program for data acquisition are located on UC Merced-SNRI digital library ( https://eng.ucmerced.edu/snsjho/files/MHWG/Field/Southern...)
