layer.temperature: Returns the average temperature of a layer between two depths.

Description

This function calculates the average temperature of a layer of water between two depths.

Usage

layer.temperature(top, bottom, wtr, depths, bthA, bthD)

Arguments

top

Numeric value of the depth (m) of the top of the layer from the water surface

bottom

Numeric value of the depth (m) of the bottom of the layer from the water surface

wtr

Numeric vector of water temperature in degrees C

depths

Numeric vector of depths (m) corresponding to water temperature vector

bthA

Numeric vector of water body cross sectional area (m2) corresponding to bthD depths

bthD

Numeric vector of water body bathymetric depths (m) corresponding to areal bthA values

Value

Numeric value of average water temperature
