lget: Convert between LISST data representations

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

Description

This set of functions allow for the convertion between lisst data types.

Usage

lget(x, type)

Arguments

x	A lisst object.
type	A character specifing the lisst data type. One of 'raw', 'cor', 'cal', 'vsf', 'vol', 'pnc', 'csa'. See details.

Details

lget dispatch the appropriate lgetxxx function acording to parameter type. As of this version is only possible to convert between 'raw', 'cor', 'cal' and 'vsf' or between 'vol' and 'pnc' (inversion not implemented).

raw

The raw digital counts as recorded by the LISST instrument.

cor

The corrected digital counts, i.e., the raw counts de-attenuated for the particle and water extinction, background subtracted and compensated for area deviations from nominal values.

cal

The calibrated values, i.e., the instrument specific calibration constants applied to the corrected values (for all variables). Aditionally, the transmittance due to particles and the particle beam attenuation are added to the lisst object.

vsf

The volume scattering function, i.e., the calibrated values normalized to incident power, the solid angle of the detectors and the path of water generating the signal.

vol

The particle volume concentration (ppm volume) per size bin, as inverted from the scattering data by the LISST-SOP.

pnc

The particle number per volume and µm size.

csa

The cross section area per volume.

See the documentation of the lget functions for further details.

l_raw <- lget(l_vsf, 'raw')
l_vsf <- lget(l_raw, 'vsf')
