Soil Moisture SK4

International Soil Moisture Network (ISMN) site within Canada’s Real-Time In-Situ Soil Monitoring for Agriculture (RISMA) network in Saskatchewan, station 4. From 2014–2021, 15-minute in-situ record comprising multi-sensor soil moisture and temperature at six depths (0–5 cm to 150 cm) and collocated meteorology. The site has frequency-domain reflectometry sensors (Stevens HydraProbe II) installed at depths of 5 cm, 20 cm, 50 cm, 100 cm, and 150 cm below the surface. An additional surface measurement of the 0–5 cm layer is also recorded, effectively providing six distinct depth readings (surface 0–5 cm, 5 cm, 20cm, 50 cm, 100 cm, 150 cm). The station also measures air temperature, precipitation, relative humidity, wind speed, and wind direction at a nearby weather station, and it monitors battery voltage for maintenance. Data from this station are logged at 15-minute intervals, providing a high-resolution time series from 2014 through 2021. This data was used to research on "Multi-Scale Soil Moisture Prediction Using Recurrent Neural Networks with Temporal Attention."
