COSMOS use at the Southern Sierra Critical Zone Observatory3rd Annual COSMOS Workshop Matthew Meadows Sierra Nevada Research Institute University of California Merced
Critical Zone Observatories http://criticalzone.org
CZO Common Infrastructure With the goal to: • resolve the evolution and formation of the CZ and its attributes • measure the properties and structure of the present-day CZ • construct carbon, mass and energy balances (event- to long-time scales)Energy
Southern Sierra Critical Zone Observatory (CZO) soil moisture measurements: • cosmic-ray • time domain reflectometry (TDR) • dielectric • neutron probe • physical sampling techniques.
Volumetric Water Content Recalibrated
Correlation of COSMOS VWC with distributed sensor network during no-snow conditions
The Future • Easy to deploy • Elevations, aspects, sets of sensors • Soil moisture and vegetation • Timing of moisture stress • Evapotranspiration • Snow and/or snow+soil storage http://criticalzone.org/
Common CZO Infrastructure • Fluxes within and across the critical zone boundaries • vegetation-atmospheric • terrestrial-aquatic • soil-atmospheric • soil-plant • bedrock-soil http://criticalzone.org/
