In jmzobitz/NEONSoils: Compute Soil Carbon Fluxes for the National Ecological Observatory Network Sites

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
