lgetcor: Retrieve the LISST corrected digital counts

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

Description

The function retrieve the corrected digital counts (lisst object type 'cor') from raw digital counts ('raw'), calibrated values ('cal') or volume scattering function ('vsf').

Usage

lgetcor(x)

Arguments

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

Details

When supplying a lisst 'raw' object, it must contain information on background values and instrument specific calibration constants. This is the case when the 'raw' lisst object was created with zscat and sn arguments set through read_lisst.

For consistency with LISST processed data provided by manufacturer, the optical transmission and the beam attenuation do not include the effect of pure water. However, the digital counts in the ring detectors are corrected for the aditional transmission loss due to pure water absorption and scattering. Values for the pure water absorption and scattering at 670 nm are taken from the Water Optical Properties Processor (WOPP) and correspond to 0.439 and 5.808e-4 1/m, respectivelly.
