Abstract: Here, the theory of Kristensen and Fitzjarrald, for the transfer function of sonic anemometers for vertical scalar fluxes, is extended from anemometers that use one vertically oriented acoustic path to measure the vertical ...

Abstract: The oxygen sensitivity of krypton and Lyman-α hygrometers is studied. Using a dewpoint generator and a controlled nitrogen/oxygen flow the extinction coefficients of five hygrometers associated with the third-order Taylor ...
