Nasapp is an odour episode management system through citizen participation. It allows to have a summary of situation in real time from any portable device or computer. In this paper we studied the advantages of incorporating the automatic calculation of trajectories models of air in each record made by volunteer citizens.

   The result is a substantial improvement in the visualization of complex problems, especially when there is diversity of odour sources. It was also verified the possibility of assigning causal percentages of odour episodes in each source, verifying meteorological and geographic influences, as well as validating the assignment of odour descriptors to known odour sources.

   D-NOSES stands for Distributed Network for Odour Sensing Empowerment and Sustainability (not to be confused with e-noses). This project has got a budget of 3.2 million Euro from the project Horizon 2020 of the European Union. The kick-off meeting just took place last week in London. A group of several companies, research universities, public administrations and NGOs will participate in this project to develop a tool for citizen odour monitoring.

 A consortium of 15 entities will participate in this H2020 project that will take 3 years. The project will co-design citizen science interventions across 7 European and 3 non-European countries, where citizens will use innovative mapping tools to crowdsource odour issues and co-create ad-hoc solutions with CSOs, NGOs, local public authorities, odour emitting industries and academia.
