Profile: Valerie Trouet

Assoc. Professor, U. of Arizona

I am an Assistant Professor at the Laboratory of Tree-Ring Research at the University of Arizona. I use tree-rings to study the climate and its interaction with forest ecosystems and focus on approximately the last 2,000 years. I am particularly interested in the reconstruction of atmospheric circulation patterns and how they influence wildfire regimes. I like to travel and have been involved in research projects in the American West, southern Africa, central and southeastern Europe, and Siberia.

NoteStreams By Valerie Trouet

Sierra Nevada Snowpack is at a Record Low

In the Mediterranean climate of California, with its warm, wet winters and hot, dry summers, the snowpack in the Sierra Nevada Mountains plays a critical role. It serves as a natural water storage system that feeds waterways and reservoirs during the dry summer months. That’s why it was very fitting that when Governor Jerry Brown announced the first-ever mandatory statewide water restrictions, he did it from the snow-barren Phillips snow course station in the Sierra Nevada. The April 1 snowpack’s water content has been measured at this station since 1941 and has averaged at 66.5 inches over this period. On April 1 2015, there was no snow on the ground.
