Abstract

Energy balance measurements were used to calculate the
evapotranspiration from some, irrigated crops in southern Idaho.
A mobile instrumented laboratory equipped with automatic data
acquisition equipment was used to make the measurements routinely
during the growing season. These included solar and net
radiation, air temperature, air humidity, air-temperature and
air-humidity gradients above the crop, soil temperature and
heat flux, windspeed, and wind direction. An electronic computer
was used to process the data recorded on perforated paper tape.
Leaf area index and soil water measurements were made routinely
in conjunction with the other measurements. A dry soil
surface during periods of partial plant cover decreased the rate
of evapotranspiration by over 50%. The total energy used in
evaporation of water increased as the season progressed, with
the amount of advected energy increasing as the crops developed
full cover.
