Southern Sierra Critical Zone Observatory (SSCZO), Providence Creek meteorological data, soil moisture and temperature, snow depth and air temperature

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://sndl.ucmerced.edu/files/MHWG/Field/Southern...)
