Changes To Snowpack Energy State From Spring Storm Events, Columbia River Headwaters, Montana, Zachary M. Seligman, Joel T. Harper, Marco P. Maneta

Geosciences Faculty Publications

The generation and release of meltwater during the spring snowmelt season can be delayed because of spring storm episodes with snow accumulation and/or sustained subfreezing temperatures. The delayed release of snowmelt often extends beyond the particular storm event because of changes to the internal state of energy in the snowpack that prevents transmission of meltwater. Following a storm, two energy deficits internal to the snowpack must be overcome before surface melt can drain and exit the snowpack: 1) cold content created by heat lost during the episode must be removed and 2) dry pore space must be filled with liquid …


Observations Of A Two-Layer Soil Moisture Influence On Surface Energy Dynamics And Planetary Boundary Layer Characteristics In A Semiarid Shrubland, Zulia Mayari Sanchez-Mejia, Shirley A. Papuga Jan 2014

Observations Of A Two-Layer Soil Moisture Influence On Surface Energy Dynamics And Planetary Boundary Layer Characteristics In A Semiarid Shrubland, Zulia Mayari Sanchez-Mejia, Shirley A. Papuga

Environmental Science and Geology Faculty Research Publications

We present an observational analysis examining soil moisture control on surface energy dynamics and planetary boundary layer characteristics. Understanding soil moisture control on land-atmosphere interactions will become increasingly important as climate change continues to alter water availability. In this study, we analyzed 4 years of data from the Santa Rita Creosote Ameriflux site. We categorized our data independently in two ways: (1) wet or dry seasons and (2) one of the four cases within a two-layer soil moisture framework for the root zone based on the presence or absence of moisture in shallow (0–20 cm) and deep (20–60 cm) soil …


Parameterization Of The Satellite-Based Model (Metric) For The Estimation Of Instantaneous Surface Energy Balance Components Over A Drip-Irrigated Vineyard, Marcos Carrasco-Benavides, Samuel Ortega-Farias, Luis Octavio Lagos, Jan Kleissl, Luis Morales-Salinas, Ayse Kilic Jan 2014

School of Natural Resources: Faculty Publications

A study was carried out to parameterize the METRIC (Mapping EvapoTranspiration at high Resolution with Internalized Calibration) model for estimating instantaneous values of albedo (shortwave albedo) (αi), net radiation (Rni) and soil heat flux (Gi), sensible (Hi) and latent heat (LEi) over a drip-irrigated Merlot vineyard (location: 35°25′ LS; 71°32′ LW; 125 m.a.s. (l). The experiment was carried out in a plot of 4.25 ha, processing 15 Landsat images, which were acquired from 2006 to 2009. An automatic weather station was placed inside the experimental plot to measure αi, …
