ts.lake.number {rLakeAnalyzer}

Calculate physical indices for a timeseries.

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.lake.number(wtr, wnd, wnd.height, bathy, seasonal = TRUE)

Arguments

wtr

A data frame of water temperatures (in Celsius). Loaded using load.ts. Must have columns datetime, wtr_##.# where ##.# is depth in meters.

wnd

A data frame of wind speeds (in m/s). Loaded using load.ts

wnd.height

Height of the anemometer above the lake surface in meters

bathy

A data frame containing hypsometric data. Loaded using load.bathy

seasonal

Boolean indicating if seasonal thermocline should be used in calculation.

Value

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