In belasi01/Cops: C-OPS Processing

Compute PAR at depth from surface irradiance (Ed0+) and profile of downwelling irradiance (EdZ)

Description

Compute PAR at depth from surface irradiance (Ed0+) and profile of downwelling irradiance (EdZ)

Usage

compute.PARz(
  Depth,
  waves,
  Edz,
  Ed.0,
  f.PAR = c(0.001, 0.01, 0.1, 0.5),
  z.fixed = c(5, 10, 20, 30, 40)
)

Arguments

Depth	is a vector of depth corresponding to the EdZ measurements
waves	is a vector of wavelength of EdZ and Ed0+
Edz	is a matrix of EdZ (col=waves; row=Depth) after nomalization to Ed.0 variation
Ed.0	is a is a vector surface irradiance
f.PAR	is a vector of numeric values corresponting to light fraction. The depth (in m) of each light fraction will be computed. Default is f.PAR=c(0.001, 0.01, 0.1,0.5)
z.fixed	is a vector of numeric values corresponting to depth at which light fraction will be calculated. Default is z.fixed=c(5,10,20,30,40)

Value

The program will return three vectors for

1. the depth of each PAR fraction requested (z.f.PAR);

2. the fraction of PAR at the depth requested (PAR.at.z);

3. the vector of PAR at all depth Z (PAR.z) in micro mol photon / m^2
