First Development Of A Gas Sensor Array For Monitoring Ammonia Surface Emission Flux From Grasslands

on .

50   Nitrogen is used in agriculture to fertilise croplands. During the spreading of fertilisers, a substantial part of Nitrogen is lost by volatilisation of ammonia (NH3). These emissions are responsible for unpleasant odours but are also mainly precursors of particulate matters (PM). In Europe, agriculture is one of the main source of nitrogen-composed PM. There is a need to collect more emissions data to understand better this activity impact.

   Measurement techniques of NH3, used for ambient air quality monitoring, are expensive and heavy to manage for the agricultural sector. Other techniques less expensive, like passive sampling, are also used to estimate ammonia flow, but these devices are not adapted for continuous monitoring. For this reason, we decided to customise a common e-nose device to detect ammonia emissions from fertilised grasslands. The sensor array was built using six commercial metal oxide semiconductor sensors. The sensors were inserted radially and evenly into a small size cylindrical PTFE chamber. Four of the selected sensors were sensitive to ammonia, one was sensitive to VOC and the last one was for combustible gas.

The European Horizon project DNOSES just published all the deliverables.

dnoses deliverablesD-NOSES stands for Distributed Network for Odour Sensing, Empowerment and Sustainability. This 3 year-long project was supported by International Associations, experts in citizen science, odour and sustainability experts, local administrations and public bodies. The deliverables of this 3.2 million Euros project are just being published, so if you wish to become a "master" in the use of citizen science to map odours, here you have much information to learn a bit more.

   This DNOSES project is a European Horizon 2020 project that studied the use of mapping odour annoyance to describe and study the impact of this environmental vector. The idea was to launch several case studies to see how better use this tool that links odour with annoyance. This project is over and now all the deliverables are available.

Version 21.09 of GRAL GRAMM just published.

on .

gral21 09   The Graz Lagrangian (GRAL) system is a Lagrangian particle model with a free Graphic User Interface (GUI) available in both Linux and Windows and it is well know among odour modellers. Now the developers have released the version 21.09 with plenty of bug fixes and new features.

    One more year, the GRAL GRAMM team have been working on changes and modifications in the code, and correcting bugs. This is the list of new features and bugs corrected for GRAL, GRAMM and the Graphic User Interface (GUI) for this release.
