What Is The Dominant Source Of Uncertainty When Mapping Basin-Wide SWE With Airborne Lidar And A Snow Model?

Aug. 3, 2018

Raleigh , Mark 1 ; Small , Eric 2 1 University of Colorado 2 University of Colorado Lidar-measured snow depth and model-estimated snow density can be combined to map snow water equivalent (SWE) across basins. This approach has the potential to transform watershed research and operations in snow dominated regions,...

The Effects Of Climate Change On An Alpine Lake System: A Mesocosm Experiment

Aug. 3, 2018

Olivier , Matthew R 1 1 INSTAAR Much like in the arctic, organisms inhabiting alpine ecosystems are living at the edge of their environmental tolerances and are thus sensitive to small changes in climate. Algal communities of alpine lakes are particularly useful as indicators of environmental change due to the...

Unraveling Complexity From Two Directions: Hydroecological Systems Seen Through The Lenses Of Modeling And Data

Aug. 3, 2018

Larsen , Laurel 1 1 Department of Physical Geography – University of California at Berkeley One consequence of earth systems moving out of a regime of stationarity is that statistical models based on past behavior may no longer be useful for predicting the future. Rather, an understanding of the mechanisms...
