Update: Urban climate network of Zurich

Almost exactly 4 years ago, we started planning an urban climate measurement network for Zurich together with meteoblue AG as part of an Innosuisse project. If we had known at the time how much work it would take to set up and maintain such a measuring network, we would probably have left it alone. Fortunately, […]

Emissions testing prospects for 2023 

As most of our active followers know, our research group is responsible for the operation, maintenance and optimization of the Swiss Mobile Aircraft Emission Measurement System (SMARTEMIS). Typically, the system is installed in test cell 1 at SR Technics, located at Zurich Airport. In 2022 however, the SR Technics management decided to reactivate their second […]

Aircraft engines: Idle/taxi gaseous emissions

The International Civil Aviation Organization (ICAO) requires that engines of maximum rated thrust greater than 26.7kN be certified for their emission performance[1]. For certification, ICAO defined four power modes in an aircraft’s landing-take-off (LTO) cycle as emission test points. These modes include idle/taxi at 7% of the maximum rated thrust (Foo), approach at 30% Foo, […]

Urban climate studies in the absence of experiments

Cities globally seek to improve the quality of living and consequently pay great attention to the effects of new constructions on the surrounding. Furthermore, there is a great demand for evaluating methods to mitigate the urban heat island effect. Exemplarily, the city of Zurich mapped out strategies on how to approach the urban heat problem […]

Studying the Interactions of Harmful Volatile Organic Compounds with Soot Particles using Dynamic Vapour Sorption

Written by: Jon G. Bell (belj@zhaw.ch) Volatile organic compounds (VOCs), such as benzene and formaldehyde, are characterised by high vapour pressures and, therefore, can easily adsorb to the surface of airborne soot particles, accumulating at the vapour-solid soot interface, within pores, or between the carbon core turbostratic graphene layers. These VOC-loaded, nanometric particles are extremely […]

Group retreat 2022 – redefining our mission

After a year of executing our previous goals and strategies and changes in personnel, the present METENVIA team embarked on a journey away from the noise of the city for a quick internal assessment and renewal, a retreat. During this period at Herzberg in Aargau, Switzerland, we evaluated and renewed our focus, strategy, and drive […]

ICAO adopts net-zero carbon emissions goal for international aviation

Written by: Thomas Rötger On 7 October 2022, at the end of 2 weeks of negotiations during the 41st ICAO Assembly, the 193 ICAO Member States took the historic decision to adopt a collective long-term global aspirational goal (LTAG) of net-zero carbon emissions of international aviation by 2050. This resolution was based upon a report on the […]

PM in Zurich, measured as LDSA (example at Schimmelstrasse)

We introduced you to the concept of lung deposited surface area (LDSA) and our network of LDSA sensors in a previous post. The idea of monitoring very fine particulate matter (PM) comes from the knowledge that up to 90% of number concentration of ambient PM comprises of particles less than 500 nm of which ultrafine […]

Conference Report: 5th International Conference on Transport, Atmosphere, Climate – TAC-5

A long-awaited return The previous installment of the TAC conferences, TAC-4, was the best conference I attended during my PhD back in 2015. A perfect combination of topics and social activities in a small Bavarian town away from touristy temptations. Naturally, TAC-5 had been on my radar, and it was initially supposed to follow the […]
