Kristine Larson, Professor at University of Colorado Boulder and Jubilee Professor at Chalmers 2011, will hold a seminar entitled "Soil moisture, snow, vegetation, and sea level measurements from reflected GPS signals".

Abstract

Geophysicists and geodesists have installed thousands of continuously-operating GPS receivers around the world to study plate motions and other geophysical phenomena. It has recently been shown that these same instruments are sensitive to signals  that reflect from the nearby environment, e.g from snow and soil moisture changes. These data can thus be used to observe and monitor spatial and  temporal changes in the water cycle - which is critical for both understanding and predicting the Earth's climate.
