Impacts of increasing aridity and wildfires on aerosol loading in the intermountain Western US

Autor: A Gannet Hallar, Noah P Molotch, Jenny L Hand, Ben Livneh, Ian B McCubbin, Ross Petersen, Joseph Michalsky, Douglas Lowenthal, Kenneth E Kunkel

Publikováno v: Environmental Research Letters, Vol 12, Iss 1, p 014006 (2017)

Feedbacks between climate warming, land surface aridity, and wildfire-derived aerosols represent a large source of uncertainty in future climate predictions. Here, long-term observations of aerosol optical depth, surface level aerosol loading, fire-a

Energy budget increases reduce mean streamflow more than snow–rain transitions: using integrated modeling to isolate climate change impacts on Rocky Mountain hydrology

Autor: Lauren M Foster, Lindsay A Bearup, Noah P Molotch, Paul D Brooks, Reed M Maxwell

Publikováno v: Environmental Research Letters, Vol 11, Iss 4, p 044015 (2016)

In snow-dominated mountain regions, a warming climate is expected to alter two drivers of hydrology: (1) decrease the fraction of precipitation falling as snow; and (2) increase surface energy available to drive evapotranspiration. This study uses a

Weekly high-resolution multi-spectral and thermal uncrewed-aerial-system mapping of an alpine catchment during summer snowmelt, Niwot Ridge, Colorado

Autor: Oliver Wigmore, Noah P. Molotch

Publikováno v: Earth System Science Data. 15:1733-1747

Alpine ecosystems are experiencing rapid change as a result of warming temperatures and changes in the quantity, timing and phase of precipitation. This in turn impacts patterns and processes of ecohydrologic connectivity, vegetation productivity and

Snowfall Fraction, Cold Content, and Energy Balance Changes Drive Differential Response to Simulated Warming in an Alpine and Subalpine Snowpack

Autor: Keith S. Jennings, Noah P. Molotch

Publikováno v: Frontiers in Earth Science, Vol 8 (2020)

Despite widespread warming in mountain regions, little research to date has explored the physical mechanisms driving the variable response of snowpacks to changes in climate, instead focusing primarily on empirical relationships, such as seasonal air

Spatial variation of the rain–snow temperature threshold across the Northern Hemisphere

Autor: Keith S. Jennings, Taylor S. Winchell, Ben Livneh, Noah P. Molotch

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-9 (2018)

Land surface models often use a spatially uniform air temperature threshold when partitioning rain and snow. Here Jennings et al. show that the threshold varies significantly across the Northern Hemisphere and that threshold selection is a large sour

Large near-term projected snowpack loss over the western United States

Autor: John C. Fyfe, Chris Derksen, Lawrence Mudryk, Gregory M. Flato, Benjamin D. Santer, Neil C. Swart, Noah P. Molotch, Xuebin Zhang, Hui Wan, Vivek K. Arora, John Scinocca, Yanjun Jiao

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-7 (2017)

Mountain snowpack in the western United States has declined over the past three decades. Fyfeet al. show that this trend cannot be explained by natural variability alone and show that under a business-as-usual scenario a further loss of up to 60% in

Recent decreases in snow water storage in western North America

Autor: Katherine E. Hale, Keith S. Jennings, Keith N. Musselman, Ben Livneh, Noah P. Molotch

Publikováno v: Communications Earth & Environment. 4

Mountain snowpacks act as natural water towers, storing winter precipitation until summer months when downstream water demand is greatest. We introduce a Snow Storage Index (SSI), representing the temporal phase difference between daily precipitation

Topographic heterogeneity explains patterns of vegetation response to climate change (1972–2008) across a mountain landscape, Niwot Ridge, Colorado

Autor: Clifton P. Bueno de Mesquita, Luke S. Tillmann, Connor D. Bernard, Katherine C. Rosemond, Noah P. Molotch, Katharine N. Suding

Publikováno v: Arctic, Antarctic, and Alpine Research, Vol 50, Iss 1 (2018)

The distributions of biomes worldwide are predicted to shift as vegetation tracks climate change. Ecologists often use coarse-scale climate models to predict these shifts along broad elevational and latitudinal gradients, but these assessments could
