ts.schmidt.stability: Calculate physical indices for a timeseries.

In rLakeAnalyzer: Lake Physics Tools

Description

Functions for simplifying the calculation of physical indices for a timeseries of observation data. Can usually be called directly on data loaded directly using load.ts and load.bathy.

These are wrapper functions that accept a timeseries of data and call the core physical metric functions (like schmidt.stability) on each timestep.

Usage

ts.schmidt.stability(wtr, bathy, na.rm = FALSE)

Arguments

wtr	A data frame of water temperatures (in Celsius). Loaded using load.ts. Must have columns datetime, wtr_##.# where ##.# is depth in meters.
bathy	A data frame containing hypsometric data. Loaded using load.bathy
na.rm	Boolean indicated if step-by-step removal of NA's should be tried. If false, a timestep with any NA values will return an NA value. If true, best effort will be made to calculate indices despite NA values.

Value

Returns a data frame with the timeseries of calculated derivatives. All include a ‘datetime’ column, but derivative columns differ between functions.

For the underlying functions operating at each timestep meta.depths, thermo.depth, schmidt.stability, lake.number, internal.energy.
