Area-weighted precipitation (mm)
Influence-area weighted rainfall; one mm over one km² equals 1000 m³.
Catchment precipitation volume (m³)
Influence-area weighted rainfall; one mm over one km² equals 1000 m³.
Symbols and units
- a
- Gauge precipitation depths (mm)
- b
- Gauge influence areas (km²)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Influence-area weighted rainfall; one mm over one km² equals 1000 m³. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
