Development of a Laser Gas Analyzer for Fast CO<sub>2</sub> and H<sub>2</sub>O Flux Measurements Utilizing Derivative Absorption Spectroscopy at a 100 Hz Data Rate

Development of a Laser Gas Analyzer for Fast CO<sub>2</sub> and H<sub>2</sub>O Flux Measurements Utilizing Derivative Absorption Spectroscopy at a 100 Hz Data Rate

We report the development of a laser gas analyzer that measures gas concentrations at a data rate of 100 Hz. This fast data rate helps eddy covariance calculations for gas fluxes in turbulent high wind speed environments. The laser gas analyzer is based on derivative laser absorption spectroscopy an...
