qc_swc_check: Check for correct values of SWC

In sapfluxnet/sapfluxnetQC1: Package with functions related to sapfluxnet project data

Description

This function informs about SWC values correctness

Usage

qc_swc_check(swc_values, parent_logger = "test")

Arguments

swc_values

vector with the swc data

Details

SWC values sometimes come in percentage instead of cm3/cm3, so this function checks three assumptions:

1. All values between 0-2. This situation is ok (it can contain out of range values, but in the same order of magnitude)

2. All values between 2-100. This situation occurs usually when values are presented in percentage. they can be safely transformed dividing by 100

3. None of the former. This is odd, so big red lights and check manually.

Value

A character indicating the assumption detected in the data
