Persistence of topographic controls on the spatial distribution of snow in rugged mountain terrain, Colorado, United States

Abstract: [1] We model the spatial distribution of snow depth across a wind-dominated alpine basin using a geostatistical approach with a complex variable mean. Snow depth surveys were conducted at maximum accumulation from 1997 through 2003 in the 2.3 km 2 Green Lakes Valley watershed in Colorado. We model snow depth as a random function that can be decomposed into a deterministic trend and a stochastic residual. Three snow depth trends were considered, differing in how they model the effect of terrain parameters on sn… Show more

“…In fact, wind has been shown to be the dominant influence on spatial variability of snow in complex terrain (Pomeroy et al, 1993;Winstral et al, 2002;Sturm and Wagner, 2010). Without prior knowledge of the spatial snow distribution in a given area, arbitrary manual snow measurements will not provide accurate estimates of snow depth over large alpine regions (Elder et al, 1991;Anderton et al, 2004;Erickson et al, 2005).…”

“…In years with high dust inputs, such as 2006 when the DOC input from wet deposition was 4300 kg C yr −1 (19 kg C ha −1 yr −1 ), the total atmospheric input could be > 5800 kg C yr −1 (24 kg C ha −1 yr −1 ) ( Table 5). Whereas atmospheric deposition occurs year long and across the entire landscape, primary production in barren soils is more patchy, occurring mainly during the summer snow-free period (approximately 90 d) (Freeman et al, 2009b) and over an area that is about half the talus area or roughly 20 % of the watershed area (Erickson et al, 2005). Our calculations show that soil primary production inputs of approximately 10 800 kg C yr −1 (calculated using the production rate of 240 kg C ha −1 yr −1 from Freeman et al (2009b) over 20 % of the watershed) are indeed higher than atmospheric inputs, as suggested by Freeman et al (2009b).…”

“…For example, several hydrological models have been applied to test the effect of the spatial distribution of a hydrological variable (e.g. specific discharge, soil moisture, or groundwater 70 recharge) (Erickson et al, 2005;Gómez-Plaza et al, 2001;Li et al, 2014). However, the effects of topography alone on hydrology are not usually addressed in those studies.…”
