The Swiss Mobile Aircraft Emission Measurement System (SMARTEMIS) is a mobile emission measurement system for particle and gas emissions from aircraft turbine engines. The prototype of SMARTEMIS was built by the Federal Office of Civil Aviation (FOCA), and further developed by Empa/SR Technics who also integrated particle measurement. The development and construction of SMARTEMIS is closely linked to the establishment of the first global non-volatile particulate matter (nvPM) standard for aircraft engines by the International Civil Aviation Organization (ICAO) that will enter into force on 1.1.2020. The nvPM sampling and measurement part of SMARTEMIS is fully compliant with the ICAO nvPM certification standard. Besides the standardized instruments for nvPM mass and number measurements, SMARTEMIS includes instruments for the measurement of particle size distribution, smoke number and the regulated gaseous pollutants (CO, HC and NOx). SMARTEMIS is usually located/installed at the SR Technics test cell but can also be transported for scientific measurement campaigns or service contracts due to the modular design of the system. The various modules can either be loaded onto a trailer designed for the system or, for longer distances, packed in customized boxes for transport by air/road cargo. SMARTEMIS has proven to be scientifically indispensable during measurements campaigns outside SR Technics: Examples are measurements on the Dassault Falcon 900EX federal jet in Payerne, Switzerland (October 2017), or measurements at engine manufacturers in Ukraine (September 2018) and Russia (October 2018).
