CentNet: A Deployable Research Network for Surface Exchange Studies

CentNet is a deployable network with 100 high-quality sampling locations for research on hydrology, vegetative canopies, urban environments, and meteorology. It gathers data on wind, temperature, humidity, pressure, precipitation, surface energy fluxes, atmospheric composition, and more using advanced sensors. Potential applications span various fields. The network is under development, and feedback is welcome.

  1. IUGG/IAMAS/JM03 #5124 CentNet – A Deployable 100-Location Network for Surface Exchange Research Steven P. Oncley, Steven R. Semmer, John Militzer, Gordon Maclean, Kurt Knudson, Christopher Golubieski, Ling-Ling Dong, Junhong Wang Potential Applications: All require high quality sampling at many locations Hydrology Vegetative Canopies Urban Canopies

  2. Observations:With commercial, new, or hybrid sensors Meteorology: - Wind (3D) - Temperature - Humidity - Pressure (microbarograph?) - Precipitation (all phases) Surface Energy Fluxes: - Sensible and Latent Heat - Radiation (4 components; direct/diffuse?) - Soil Heating (Flux, temperature, moisture, Cp) Atmospheric Composition: - CO2 - Total column water vapor? - Ozone? - Aerosol size distribution? Surface Characterization - Camera - PAR (photosynthetically active radiation) - Radiative Surface Temperature - NDVI? - Sap Flow?

  3. Networking:Multi-level to conserve power; All samples transmitted Under Development: Input Welcome!
