Impact of Continuous Cropping on the Diurnal Range of Dew Point Temperature during the Foliar Expansion Period of Annual Crops on the Canadian Prairies

Figure 1

Map of the study area with representative climate stations in the subhumid and semiarid climatic zones. Climatic zones were delineated based on precipitation to potential evapotranspiration (P/PE) ratio (subhumid if P/PE ≥ 0.52, semiarid if P/PE < 0.52). Ecodistricts containing a selected climate station are highlighted in red. Land, crop and summerfallow area for these ecodistricts are given in Table 1.
