We are doing science for policy
The Joint Research Centre (JRC) is the European Commission's science and knowledge service which employs scientists to carry out research in order to provide independent scientific advice and support to EU policy.
The DELTA software is an IDL-based software developed in the framework of FAIRMODE. It supports the evaluation of model applications performed in the frame of the Air Quality Directive. Based on paired modelled and monitored data, it offers rapid diagnostic of model performance in terms of various statistical indicators and diagrams. Some of these statistical indicators are evaluated against bound values (model performance criteria) to facilitate the benchmarking of the user's model application against agreed quality standards.
