In addition, NIKLAS checks the variability and the inner consistency of data while using familiar relations for example between temperature and dew point temperature. The result of the tests is categorized into three different levels: valid, limited quality and bad quality.
NIKLAS is working as a pure controlling tool and deletes data intervals with bad quality from the time series and replaces it with a gap marker.
NIKLAS is a windows application with a graphic user interface. It has been successfully used for real time applications (Mosel flood warning system TIMISflood) and has been used for offline data control for climate change analyses (ExUS (climate study for North Rhine Westphalia); Sachsen-Anhalt climate study).
