Can weighing lysimeter ET represent surrounding field ET well enough to test flux station measurements of daily and sub-daily ET?

► Evapotranspiration measured by weighing lysimeter may not match that in the field. ► Neutron probe field soil water balance and lysimeter measures of ET were compared. ► Field ET matched lysimeter ET for one field throughout the growing season. ► In another field, field ET was less than lysimeter ET during vegetative growth. ► Simple soil water balance compared well with a zero flux plane approach.
