Temperature Toolbox

This site is designed for people studying processes related to temperature in complex terrain. Extensive site-specific studies have been carried out across the globe. Here we strive to collect that information in one place and provide a set of tools that can easily be downloaded and used by anyone.

Temperature sensors in evergreen trees

Extensive work has gone into finding an inexpensive radiation shield for an inexpensive temperature sensor. In many mountain environments, evergreen trees provide an ideal option. Lundquist and Huggett (2008,  Water Resources Research) describe this research.


Are the mountains warming faster or slower than the lowlands?
It depends critically on where you are. Pepin and Lundquist (Geophysical Research Letters, 2008) demonstrate that long-term temperature stations near the 0-degree isotherm are warming faster than global averages, but overall, the scatter in long term trends in mountainous areas is large.
Above the snow

In the Pacific Northwest, snow can be up to 40-feet deep, so innovative techniques are needed to place sensors high enough in the trees.
