Campbell Scientific offers research-grade instrumentation for micrometeorological applications including measurement of sensible heat, water vapor and trace gas fluxes, and atmospheric variables required by air quality dispersion models. We also offer a variety of automated weather station configurations. 




Surface Flux Measurements

Our flux systems can measure atmospheric gradients or vertical turbulent transport directly. Standard systems that support either aerodynamic or Bowen ratio gradient techniques are available for measuring heat, water vapor, and CO2 fluxes. Our standard eddy covariance systems use a three-dimensional anemometer and either an open-path krypton hygrometer or our EC150 open-path or EC155 losed path H2O and CO2 analysers. Measurements of other trace gas fluxes, such as N2O and CH4, are obtained with our TGA100 tunable diode laser analyser. Most sensors and analysers, including those made by other manufacturers, interface directly to our dataloggers.

Common sensors used in our micromet systems include sonic anemometers, hygrometers, fine wire thermocouples, and open and closed path gas analysers, including the EC150 open path gas analyser. A wide variety of meteorological and soil sensors can also be used.
