Calculation method
Calculation method
Up-crossing times (seconds)
Interpolate crossings where elevation moves from strictly negative to nonnegative.
Complete wave [start,end,period,height]
Consecutive up-crossings; height=max−min including interpolated zero endpoints and contained samples.
Symbols and units
- a
- Ordered sample times (seconds)

- Surface elevations around supplied zero datum (m)
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
- Surface elevation-time samples, crossing convention. Returns Individual wave heights and periods. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Ordered sample times (seconds): minimum None, maximum 1000000000000.0. Surface elevations around supplied zero datum (m): minimum None, maximum 1000000000000.0.
