Soil moisture (m3/m3) and temperature (°C) were measured at 10-minute intervals at depths of 10 cm, 20 cm, 40 cm, 60 cm and 80 cm in a crop rotated field in West Lafayette, IN (40.48128°, -87.00031°). Data were collected from water years 2018 (10/1/2017 - 9/30/2018) to 2019 (10/1/2018-9/30/2019). Data were screened to ensure quality of data and no gaps in time-series. Null data values were replaced with -9999 when sensors were not recording data. For instance, sensors were turned off intermittently during harvest of the 2018 water year.
Soil Moisture Content (SMC) and soil temperature were collected with a Decagon (METER Group) 5TM sensor. The SMC represents the liquid content in the soil that can experience freezing. The SMC measurements range from 0.0 to 1.0 m3/m3 with a resolution of 0.0008 m3/m3 from 0.0 to 0.50 m3/m3. The temperature measurements range from -40°C to +60°C with a resolution of 0.1°C. Data were stored on an Em50 data logger and offloaded weekly.
