Measurements of the diurnal and height variation of the dew-point temperature in three types of ground cover (corn, soybeans and bare ground) were made in 1948 at Ames, Iowa, using a photoelectric dew-point hygrometer. The variations are expressed as the standard deviation of a frequency distribution of the dew-point temperatures taken at half-second intervals during a minute run.
