lgetvsf: Retrieve VSF from LISST data

In AlexCast/lisst: Functions for manipulation of the Laser In-Situ Scattering and Transmissometry (LISST) data

Description

The function retrieves the particle Volume Scattering Function (1/m/sr) for LISST data.

Usage

lgetvsf(x)

Arguments

x	A lisst object of type 'raw', 'cor', 'cal' or 'vsf'.

Details

Types 'raw' and 'cor' are converted to 'cal' first. The function then normalizes the power (mW) measured by the ring detectors by their solid angle (sr), the path of water generating the signal (m), and the power entering the path (mW). Since when generating 'cor' the measured signal is already de-attenuated from pure water extinction, no additional correction is necessary.
