Maurizio Gualtieri of project partner ENEA has provided an update illustrating some of the work progressing between February and November 2018 under WP2 of the tests performed at INNOVHUB on the dilutor system ENEA have developed. The different tests performed at Innovhub aimed at the evaluation of the rate of condensation of the compounds used… Read More


Sara Janhäll, Daniel Bäckström and Lennart Gustavsson of project partner RISE have produced a report derived from A2.1.4* under WP2. Emissions of particles and organic compounds from small and medium scaled biomass combustion provides background information both on different emission standards used in combustion appliances and on the development of the particles from the combustion… Read More


Guillermo Guarnizo of project partner UC3M has provided an update illustrating the work progressing between February and November 2018 under WP2. After the completion of the A2.3.1 survey (November 2017), UC3M has focused attention on activity A2.3.3* related to FTIR spectroscopic techniques and primarily on the development of retrieval algorithms for identification and quantification of… Read More


Daniel Bäckström of project partner RISE who has provided some photos illustrating the work progressing under Activity 2.1.2. of WP2. For A2.1.2, INERIS, RISE and DTI will each perform on the INERIS Stack Simulator Facility solid PM and OGC measurements in accordance with EN_PME_TEST. Photo 1 shows the Intercomparison of the test method EN-PME-TEST performed… Read More


Francesco D’Amato of project partner CNR-INO has provided an update on the work progressing under WP1: Measurements of Ammonia mixing ratio for the assessment of the behaviour of Direct Absorption vs Derivative techniques One of the main problems of measuring the mixing ratios of gaseous molecular species in stacks is the interference due to the… Read More


Sara Janhäll of project partner RISE (Research Institutes of Sweden) recently presented on the IMPRESS 2 Project at the 8th biennial meeting of the Gothenburg Air and Climate Centre. The event brought together people interested in issues ranging from air quality, to weather forecasting and climate change to discuss current and future areas of research… Read More
