Analyzing the Suitability of Remotely Sensed ET for Calibrating a Watershed Model of a Mediterranean Montane Forest
Autor: Steven M. Jepsen, Thomas C. Harmon, Bin Guan
Publikováno v: Remote Sensing, Vol 13, Iss 7, p 1258 (2021)
The ability to spatially characterize runoff generation and forest health depends partly on the accuracy and resolution of evapotranspiration (ET) simulated by numerical models. A possible strategy to increase the accuracy and resolution of numerical

Droughts constitute natural hazards that affect water supply for ecosystems and human livelihoods. In 2013&ndash
2016, the Caribbean experienced the worst drought since the 1950s, and climate projections for the southern Caribbean predict less r

Snow water equivalent in the Sierra Nevada: Blending snow sensor observations with snowmelt model simulations
Autor: Steven M. Jepsen, Jeff Dozier, Thomas H. Painter, Duane E. Waliser, Noah P. Molotch, Bin Guan
Publikováno v: Water Resources Research. 49:5029-5046
[1] We estimate the spatial distribution of daily melt-season snow water equivalent (SWE) over the Sierra Nevada for March to August, 2000–2012, by two methods: reconstruction by combining remotely sensed snow cover images with a spatially distribu

Sediment Melt-Migration Dynamics in Perennial Antarctic Lake Ice
Autor: Steven M. Jepsen, John C. Priscu, Edward E. Adams
Publikováno v: Arctic, Antarctic, and Alpine Research. 42:57-66
We examined sediment melt-migration dynamics in the ice cover of Lake Fryxell, Taylor Valley, McMurdo Dry Valleys, Antarctica, using a combination of laboratory experiments, field observations, and modeling. The specific objectives were to determine

A bonding process between grains in mechanically disaggregated snow
Autor: Bryan Close, Edward E. Adams, Steven M. Jepsen
Publikováno v: Annals of Glaciology. 48:6-12
Collections of disaggregated snow particles were examined in a temperature-controlled microscope stage. In addition to necks that appeared to sinter in a manner congruent with the two-particle model, there also appeared unanticipated dendritic growth
