Christian Mätzler studied physics at the University of Bern with subsidiaries in mathematics and geography. He made postdoctoral studies at the NASA Goddard Space Flight Center and at the ETH in Zurich. Today he is Titularprofessor in Applied Physics and leader of the Project Group "Radiometry for environmental monitoring" at the Institute of Applied Physics, University of Bern. His studies have been concentrated on surface-based microwave (1-100 GHz) signatures for active and passive remote sensing of snow, ice, soil, vegetation and atmosphere, as well as the development of methods for dielectric measurements of these media, while complementary work is done at optical wavelengths. He is interested in an improved physical understanding of the observed processes and in the interactions between surface and atmosphere. Based on experimental work of his group, he is currently developing and testing a microwave (1-100 GHz) emission model for layered snowpacks (MEMLS) including structural information of each layer.

Role in the SMOS mission:
- complex dielectric constant and penetration depth modeling and measurements (ice, snow, sand, vegetation, and possibly others) at L Band and above.
- radiative transfer and emission modeling (ice, snow, sand) at L Band and higher frequencies (e.g. snow emission model MEMLS ).
- simulation of Tb values with above models
- consideration of relief effects.
