EarthScience Experimental Facility Design of the Institutional Experiment A Biosphere2-Hydrologic Synthesis co-production
EarthScience Experimental Facility • Three bays available for institutional experiment • Precise climate and mass balance control • Hydrologic, biogeochemical, geomorphologic, ecologic interactions • Intermediate spatial scale (30mx15m) • Both event-based and long-term (10 years) observations
