Tidevannsdata fra Meteorologisk institutt, Stavanger

For eksempel, hvis 75p er 0,14, betyr det at 75% av prognosene er under 0,14 mens 25% er mer enn det. Kilde: api.met.no/weatherapi/tidalwater/1.1/documentation --- ## EN: The dataset contains data about tidal water level in Stavanger, provided by the Norwegian Meteorological Institute. The values are given in meters above mean sea level, and attempt to predict the tide for the next 3 days.

See the link: kartverket.no/sehavniva/data-pa-se-havniva/viktige-vannstandsniva/ for further information on the reference water level. “Tidal forces (TIDE) and the influence of weather (SURGE). Tidal forces is the basis for calculating water level. Forecast of weather conditions for the specified harbor is then used to adjust this basis (TOTAL).

Waves are not included in the forecast, only long period phenomena.” ### Columns #### AAR, MND, DAG, TIM Year, month, day and hour (in UTC) respectively #### PROG Prognosis length (time since model run) #### SURGE Influence of weather (wind, air pressure) #### TIDE Tidal forces (astronomical data from Kartverket) #### TOTAL Total water level (sum of SURGE and TIDE) #### 0p, 25p, 50p, 75p, 100p Percentiles of SURGE, i.e. how many of the ensemble forecasts are below the indicated (absolute) value.

E.g. if 75p is 0.14, this means 75% of the forecasts are below 0.14 while 25% are more than that. Source: api.met.no/weatherapi/tidalwater/1.1/documentation
