The site is located in eastern Ontario, Canada. The climate is humid continental with a large seasonal climatic variation, supporting one harvest per year. The dominant soil is silt loam. Agriculture and Agri-Food Canada (AAFC) has a permanent in situ soil moisture station network in the area ( The site has been used extensively to develop and validate soil moisture retrievals using Canada’s RADARSAT satellites.

Soil moisture, soil temperature

  • Crop Type(s):
  • Collection Protocol:

    Permanent in situ soil moisture network are installed in this site. The network consists of five monitoring stations. At each station three Stevens Hydra probes have been placed at each of four depths – 5, 20, 50 and 100 cm. Each probe records soil moisture percentage (using Stephen’s default dielectric conversion model), soil temperature in Celsius and real soil dielectric permittivity.

  • Frequency: Measurements are collected on a 30 minute time scale
