Presentation by Albin

Today Albin was invited at the Institute of Meteorology and Geophysics of the University of Innsbruck to present our recent modelling work on grassland carbon and water cycling in their weekly seminar series. The presentation, which covered much of the work we have been doing over the past two years within the frame of the GrassClim project, can be found here.

Mountains under Watch 2013 conference

We have been attending the Mountains under Watch 2013 conference in Bard (Valle d’Aosta, Italy) 20-22 February 2013. Georg gave a keynote lecture on “Effects of global changes on mountain ecosystems” (watch video (external link) recorded by Greg Greenwood from MRI) and Albin a talk on “As simple as possible, but not simpler than that: An efficient soil water content model for broad ecological applications”.
