Abstract
Abstract The amount of dewfall and dewrise to a corn canopy has been estimated over 7 nights by using the Bowen ratio energy balance technique and the soil diffusivity technique, respectively. In addition, the distribution of free liquid water within the plant community has been measured by using Leick plates. By combining the Leick plate results with the foliage area distribution of the plant canopy, the total amount of dew deposition within the plant canopy can also be estimated. On average, both techniques did not show a systematic difference and agreed to within 10%. Moreover, it appeared that the nondimensionized dew profiles within the stand showed a more or less similar shape for all nights. The potential dew formation was calculated for all nights. On average, the potential dew was 30% higher than the actual dew. This offers the opportunity to make reliable total dew estimates, and also, due to similarity, dew profile estimates for a corn canopy from simple micrometeorological data. Model calculat...
