get_epoch: Retrieve the tidal epoch

In ccb60/SLRSIM: Tools to Analyse Sea Level Rise

Description

For most US tidal stations, the function currently returns c(start = 1983, end = 2001) but some stations on the Gulf Coast and Alaska have "anomalously high" sea level rise rates, and so tidal forecasts have been calibrated based on a more recent five year period, usually 2012 through 2016. For those Stations, this function will return c(start = 2012, end = 2016).

Usage

get_epoch(.station)

Arguments

.station

Details

The function is especially useful for international stations, where the period used to calculate tidal statistics my be different. NOAA is expected to adopt a revised tidal datum in 2025.

Value

A named list of two integers, representing the starting and ending years of the official tidal epoch.
