Determination of carbon dioxide concentrations in air from livestock housing systems : reference method using the lung method as applied by Wageningen Livestock Research

This document provides a description of the lung method as applied by Wageningen Livestock Research (WLR lung method). This measurement method is commonly used as a reference method for carbon dioxide concentration measurements from agricultural activities (livestock housing, manure storage). The objective of this document is to specify the performance characteristics of the method, and the procedure for preparation and deployment of this method in practice to measure CO2 concentrations from livestock housing systems.
