About the AAFC RISMA Portal
About the Portal
Soil moisture is a critical variable in agri-environmental monitoring as it often determines rates of crop growth and productivity, rates of soil biogeochemical processes that impact soil fertility and determines boundary layer conditions that drive meteorological processes. In 2010 and 2011, Agriculture and Agri-Food Canada (AAFC), with collaboration from Environment Canada, established three in situ monitoring networks near Kenaston SK, Carman MB and Casselman ON as part of the Sustainable Agriculture Environmental Systems (SAGES) project titled Earth Observation Information on Crops and Soils for Agri-Environmental Monitoring in Canada. The near real time in situ soil moisture/temperature and precipitation data from these three networks are used to calibrate and validate remote sensing and modelled soil moisture products. By 2014, most of the in situ stations in the Saskatchewan and Manitoba networks will be equipped with additional meteorological sensors to complement the existing data with air temperature, relative humidity, wind speed and wind direction.

Data on the Portal
The RISMA Portal provides web-based access to soil moisture data collected by AAFC. It does this using open standards such as OGC SOS. This data is then cached and near real-time observations can be viewed in an interactive web page for the various locations.
AAFC has continued the RISMA project and is now hosting the data and project on their own website.
