Abstract

Solar reflectance from soil and crop surfaces was measured
with two Eppley pyrheliometers, one mounted upward and the other
downward. Periodic measurements of one to several days' duration
were taken over corn, sugar beets, alfalfa and barley at various
stages of growth during the growing season. In addition, reflectance
values were obtained for bare soil (Fort Collins clay loam), both wet
and dry, and for other cultural variations including irrigation, cultivation,
crop removal, etc. Results are expressed as the ratio of
reflected to incoming short-wave radiation for a solar day.
