Scientific dataset observed by instruments usually includes some outlier values which have to be flagged in data quality control process. OutlierFlag was developed to make it accurate and easy by providing a suitable outlier data flagging algorithm and a friendly GUI. There are three steps of limitation, error and standard deviation checking one by one in the algorithm and several parameters are configurable so the algorithm can be used for various datasets... Statistical analysis of air mass back trajectories combined with long-term ambient air pollution measurements are useful tools for source identification. Using these methods, the geographic information system (GIS) based software, TrajStat, was developed to view, query, and cluster the trajectories and compute the potential source contribution function (PSCF) and concentration weighted trajectory (CWT) analyses when measurement data are included... The wContour class library was developed using Java and C# to implement the..
