PET zone estimation methodology for mountainous terrain. (a) Temperature distribution estimated from the lapse rate (−9.8°C per 1000 m increase in elevation); (b) solar radiation classes (range of zones: Zone 1—consisting of steep north-facing slopes with reduced radiation from mountain shadow, to Zone 5—high altitude, south facing slopes not impeded by mountain shadows); (c) merged PET zones (42 PET permutations across the watershed).
