Campbell Scientific’s IRGASON® fully integrates the open-path analyzer and sonic anemometer. Designed specifically for eddy-covariance carbon and water flux measurements, the patented design is easier to install and use than separate sensors and provides increased measurement accuracy. The IRGASON® simultaneously measures absolute carbon dioxide and water vapor, air temperature, barometric pressure, three-dimensional wind speed, and sonic air temperature. U.S. patent D680455 For more information about the benefits of having a colocated measurement, refer to the poster "Improved eddy flux measurements by open-path gas analyzer and sonic anemometer co-location."
