Abstract: The objective of this study was to improve the accuracy of net radiation (Rn) measurements under conditions conducive to dew or frost deposition. Two nonventilated net pyrradiometers were mounted over grass during November ...

Abstract: Drought on the Canadian prairies is the single most limiting factor to crop yield. Several indices have been developed that indicate the onset, severity, and persistence of drought. This study was conducted to assess the ...

Abstract: The Canadian prairies are a major producer of grain, much of which is produced under rain-fed agriculture. The amount and timing of precipitation are critical to grain production. Information on the precipitation trend is ...

Abstract: Regression analysis was used to establish linear trends of rainfall amounts and number of events at 140 stations with 40 years of record across the Canadian prairies. Annual rainfall was further split into three 4-month ...

Abstract: The automation of weather stations necessitates an alternative approach to the traditional manual measure of free-water evaporation made using a class A pan. This study compared commercially available water-level sensing ...
