measurement_detect {neonSoilFlux}

Internal function that makes sure for each time, position, and depth we have at least two data points for soil temp and soil h20, 3 for soil co2

Description

Given a merged data frame of co2, water, and temperature: 1) Filters on QF measurement flags 2) Filters if we have at least 2 soil h20 and temperature measurements, 3 co2 measurements at each time, horizontal position, and vertical depth 3) Filters if we have at least 3 distinct measurements at each time and horizontal position 4) Returns the resulting data frame.

This internal function is created to speed up data processing.

Usage

measurement_detect(input_data)

Arguments

input_data

Required. Nested data frame of merged soil water, temperature, co2, and pressure across different NEON locations and depths

Value

Data frame of fluxes from the timeperiod
