This effort is for instrumentation in snow hydrology research to support ongoing and new research efforts to understand the physical processes that control snowpack dynamics. Instrumentation from this grant will be deployed and complement existing instrumentation at an alpine site on Niwot Ridge in the Colorado Front Range of the Rocky Mountains.
Snow-atmosphere energy fluxes will be measured to validate and calibrate energy balance snowmelt models. These measurements will complement existing equipment to measure snowmelt quantity and timing, including 16 snowmelt lysimeters currently installed and another 116 snowmelt lysimeters to be installed in the summer of 1997. Additionally, we will include a comparison of the Aerodynamic Profile Method (APM) and the Eddy Correlation Method (ECM) to measure turbulent fluxes. Our objective here is to derive a site specific Monin-Obukov similarity relation for the inexpensive APM from the expensive and intensive ECM that can then be generalized over a wide range of snow conditions and areas.
