metadata: Extract metadata from lisst objects

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

Description

This collection of functions allows to extract specific metadata stored in the lisst object.

Usage

zscat(x)

fzscat(x)

lity(x)

ltime(x)

angles(x, units, medium = c("water", "air"))

sizes(x, units)

Arguments

x	A lisst object.
units	Desired units.
medium	Desired medium (water or air).

Details

These functions are the recommended way to access the object's metadata since metadata organization might be subject to change.

Value

The returned data is dependent on the specific metadata requested:

• ltyi - A character indicating the LISST SOP inversion type (rs or ss) if any;

• sizes - A numeric matrix with the minimum, maximum and median sizes in each bin;

• angles - A numeric matrix with the minimum, maximum and median angles in each bin;

• ltime - A POSIXct vector of recording times;

• zscat - A numeric vector with background scattering values (blank);

• fzscat - A numeric vector with factory background scattering values (blank).

Functions

• zscat: Extract background scattering

• fzscat: Extract factory background scattering

• lity: Extract inversion type

• ltime: Extract lisst time index

• angles: Extract reference measuring angles

• sizes: Extract reference inversion sizes
