Data is checked for any outlier measurements caused by mechanical failure of the sampling systems or errors of the analytical instruments.
Gaps and errors in the data are corrected for by replacing them with gap-filling estimates. These are formulated by extrapolating from more reliable data acquired before the gap or from the emission patterns of the previous days, seasons or cropping cycles.
Generally this large amount of raw data collected at high frequency cannot be used immediately for data analysis. The data stream is converted into daily averages that are easier to interpret and which smooth out the inherent variability of individual measurements.
Measuring N2O emissions from Australian soils The objective of the N2O Network is to develop best management practice strategies to reduce greenhouse gas emissions from agricultural soils. The research is a multi-step process. It starts with an experimental design for investigating a scientific question and ends with findings that may impact farming practices and government policy.
