tidedata: Tidal constituent information

Description

The tidedata dataset contains Tide-constituent information that is use by tidem to fit tidal models. tidedata is a list containing [object Object],[object Object],[object Object] Apart from the use of d1 through d6, the naming and content follows T_TIDE. All of this is based on Foreman (1977), to which the reader is referred for details.

To get a list of all the available tidal constituents, do cat("all constituents:",tidedata$const$name) and to get a list of the so-called standard coefficients, do cat("standard constituents:",tidedata$const$name[tidedata$const$ikmpr])

Usage

data(tidedata)

source

The data come from the tide3.dat file of the T_TIDE package (Pawlowicz et al., 2002), and derive from Appendices provided by Foreman (1977). The data are scanned using tests/tide.R in this package, which also performs some tests using T_TIDE values as a reference.
