Snowpack impacts and trends in precipitation regimes are investigated for the mountainous western United States from water years 1984–2016. The vast majority of snow trend studies utilize undifferentiated air temperature records, which do not segregate between days with and without precipitation and effectually dilute temperature trends relevant for snowpack monitoring....
The H. J. Andrews Experimental Forest in the Cascades of
central Oregon provides a unique opportunity to study spatial
climate patterns on a relatively small scale. Historical
records at the 64 square-kilometer site provide a spatiallydense
30-year dataset. Thermal regimes at the H. J. Andrews
are generally known but the...
A non-intrusive measurement technique for direct quantitative thermal visualization of channel wall temperatures in two phase microchannel flows using infrared thermography (IRT) is presented. Specifically, the measurement of top channel wall temperatures in a fractal-like branching microchannel silicon heat sink during flow boiling is demonstrated and thoroughly documented. Obtaining quantitative...
