eta_to_dbz: Convert reflectivity (eta) to reflectivity factor (dBZ)

In adokter/bioRad: Biological Analysis and Visualization of Weather Radar Data

Convert reflectivity (eta) to reflectivity factor (dBZ)

Description

Converts reflectivity (eta) to reflectivity factor (dBZ).

Usage

eta_to_dbz(eta, wavelength, K = sqrt(0.93))

Arguments

eta	Numeric. Reflectivity, in cm^2/km^3.
wavelength	Numeric. Radar wavelength, in cm.
K	Numeric. Norm of the complex refractive index of water.

Value

Reflectivity factor, in dBZ.

Examples

# Calculate dBZ for a 10000 cm^2/km^3 eta reflectivity at C-band
eta_to_dbz(10000, 5)

# Calculate dBZ for a 10000 cm^2/km^3 eta reflectivity at S-band
eta_to_dbz(10000, 10)

# Calculate dBZ for an animal density of 1000 individuals/km^3 and a radar
# cross section of 11 cm^2 per individual
eta_to_dbz(1000 * 11, 5) # C-band
eta_to_dbz(1000 * 11, 10) # S-band
