Automated Data Selection / Filtering methodologies for the case of CO2


The Global Atmosphere Watch (GAW) Programme of the World Meteorological Organization (UNO/WMO) stands for a worldwide database of high-quality atmospheric data with best possible comparability. It is of crucial interest to find a best suitable set of automated data selection/filtering methodologies for flagging non-representative data in the measurements, which can be applied for a larger number of measurement stations. A statistical data selection method called Adaptive Diurnal Minimum Variation (ADMV) has been developed and applied to atmospheric CO2 measurements at six GAW mountain stations in Europe for evaluation. The corresponding paper has been submitted and currently under review by the journal Atmospheric Measurement Techniques (AMT).

Meanwhile, more researches are carried out on the long-term measurements of CO2 and other trace gases at GAW global station Zugspitze-Schneefernerhaus. Further researches will focus on evaluation and strategical combination of different data selection methods.
