Description

Calculation of atmospheric molecular backscatter coefficient at specified pressure, temperature and wavelength.

Usage

1
betamol(P, T, lambda = 1064)

Arguments

P

Pressure in hPa. can be scalar, vector or matrix of the same dimension of T.

T

Temperature in °k. can be scalar, vector or matrix of the same dimension of P.

lambda

Scalar value in nm. It represent the wavelength of incident light.

Value

Return according to the dimension of P and T returns the volume backscatter coefficient [1/m 1/sr] for the specified wavelength lambda.
