- •
We characterize bare soil evaporation following precipitation using weighing lysimeters.
- •
Effective precipitation is sensitive to antecedent soil water content.
- •
Effective precipitation is also influenced by ET demand following the event.
- •
Precipitation events less than 10 mm are negligible for most irrigation scheduling.
