The following sites are: % Parameter set calculated from data on Parlung Glaciers (this study) % Parameter set from Shea and Moore (2010) for Rockies- Canada (Published parameters) % Parameter set from Carturan et al. (2015) for Ortles Cevedale, Italy (k1/k2 data from author) % Parameter set from Shaw et al. (2017) on Tsanteleina Glacier, Italy (Reassesed parameters) % Parameter set calculated from data of Bravo et al., (2019) on South Patagonian Icefield (SPI), Chile % Parameter set calculated from data of Bravo et al., (2017) on Universidad Glacier, Chile % Parameter set calculated from data of Ayala et al., (2015) on Arolla Glacier, Switzerland % Parameter set calculated from data of Ayala et al., (2015) on JuncalNorte Glacier, Chile % Parameter set calculated from data of Troxler et al., (2020) on McCall Glacier, Alaska % Parameter set calculated from data of Greuell and Böhm (1998) on Pasterze Glacier, Austria % Parameter set calculated from data of Rets et al., (2019) on Djankuat Glacier, Russia % Parameter set calculated from data of Pradhananga et al., (2020 In prep) on Peyto Glacier, Canada Variables include: 'Name' = name of individual observation station (AWS or Temp/RH 'T-logger') 'Elevation' = Elevation (m a.s.l.) of given observation station 'Flowline' = The distance along the glacier flowline from an upslope summit or crest (m) 'k1' = The climatic sensitivity (ratio) of on-glacier temperatures to changes in the ambient (off-glacier) air temperature below the onset of katabatic onset (following Shea and Moore, 2010) 'k2' = The climatic sensitivity (ratio) of on-glacier temperatures to changes in the ambient (off-glacier) air temperature above the onset of katabatic onset (following Shea and Moore, 2010) 'Tst' = The T* parameter that defines the threshold (off-glacier) temperature for katabatic conditions parameterised following Carturan et al.
