Abstract

A single-beam infrared absorption hygrometer for measuring fluctuations in atmospheric water vapour and suitable for use in eddy correlation studies of evatranspiration is described. This instrument differs from previously described devices since it incorporates a method for monitoring detector responsivity and correcting for temperature-induced changes in this responsivity. Without such a correction, changes in the hygrometer calibration coefficient, due to instrument temperature effects, can be as large as 30% during energy balance studies over grassland.
