• Manitoba Agriculture Weather Program operates anetwork of 108 solar powered weather stations usingresearch-grade sensors. Each station is visited at leasttwice every year for maintenance and sensor calibration.
• Weather data collected at each station includes airtemperature and humidity at 2 m above ground; windspeed/direction at 10 m; soil temperature and moistureat 5, 20, 50 and 100 cm depths; solar radiation at 2.5 m;all-weather precipitation gauge at 1.5 m; tipping bucketrain gauge at 1 m and barometric pressure at 1.5 m.
• Each station records data at fifteen minutes, hourly anddaily intervals. Data from the sensors are transmittedevery 15 minutes from April 1 to October 31 but reducedto hourly from November 1 to March 30 to minimize theload on power supply during cold winter months.
