Abstract
Eddy correlation measurements of water vapor flux density have been made by using a barium fluoride film humidity sensor and a three‐dimensional anemometer. During morning and evening periods, good agreement was obtained between eddy correlation data and two independent methods. Serious disagreement between measurements occurred only when the humidity sensor was operating within a poorly defined portion of the calibration curve that was not suited to on‐line calculations. The results indicate that the humidity sensor could be modified to allow operation at all times within linear segments of the calibration curve, thereby permiting successful on‐line computer calculations of eddy correlation vapor flux within one meter of the surface.This publication has 11 references indexed in Scilit:
