EC Flux Towers providing eddy-covariance (EC) system comprised of an open path gas analyzer and three dimensional (3D) sonic anemometer, which are of standard use nationally and internationally by AmeriFLUX and FLUXNET as well as the USDA-ARS LTAR network. SAWS requires 4 EC systems to estimate water, energy, and carbon fluxes typically observed over California orchards and other irrigated crops. We require the EC flux measurement systems with programmable dataloggers to fully integrate the open-path gas analyzer and 3D sonic anemometer as a single unit instead of separate sensors which will provide increased measurement accuracy. These sensors are complemented by several ancillary measurements, which are essential to contextualize the observation and accurate estimations of land surface fluxes. Sensors must be waterproof and rugged, be able to operate in -10 to 60 °C (or more) and in 0 to 100% humidity while providing accurate high frequency measurements. Sensor package must be able to be read with existing Campbell Scientific EZflux software. See attached sources sought document for more information.
