Putting the applied in applied meteorology

As part of the Atmospheric Physics and Applied Meteorology course for Aviation studies at ZHAW, we carry out a vertical sounding of the atmosphere during lab hours. A radiosonde is attached to a weather balloon which then ascends through the atmosphere, measuring temperature, moisture, pressure, altitude, and its location along the way. As the balloon […]

Spray mist cooling of open spaces

Once again, it’s Hot in the city! with yesterday’s air temperatures above 30 °C across Switzerland and exceeding 34 °C in Basel. Cities struggle with this excessive heat and are exploring ways to protect their citizens and make the outdoor spaces more pleasant. We have already written about the exciting outdoor spray mist cooling pilot […]

Engaging the community – expanding urban temperature measurements into private space

In our endeavor to comprehend urban climate and the emergence and impact of heat islands, we have already undertaken several projects, as regular readers of our blog are aware. These include temperature measurements in the cities of Zurich and Winterthur. While these two measurement networks differ in their setup – in Zurich, the measurement stations […]

A unique air quality study? Part 2

In spring three years ago, in the middle of the first lockdown of the Covid-19 pandemic in Switzerland, we packed up our measurement system (SMARTEMIS) and drove to Zurich Airport to record unique air quality data near the airport area. At this time, aircraft movements had dropped by more than 90% compared to the previous […]

Hot in the city

Whereas Billy Idol enjoyed the hot summer nights in New York City, many urban dwellers nowadays wish for colder urban environments. We at ZAV investigate the urban climate and potential measures to mitigate the increasingly high temperatures within the urban heat island. Zurich’s dense urban measurement network provides an ideal dataset for comparison with and […]

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, […]

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 […]

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 […]

Tropical nights in Zurich and in Basel – a preliminary analysis of the Summer 2022

Although the official summer season is far from ending, it is probably safe to say already now that Switzerland is currently experiencing one of the sunniest, driest and hottest summer of the last decade. As published within the MeteoSwiss Climate-Blog article from July 29th 2022, July 2022 is ranking as the fourth warmest July (after […]

One ring to cool them all?

Passersby strolling across Turbinenplatz in Zurich these days, are treated with an unusual sight: A construction made of wood, strings and a metallic ring , hovering a few meters above ground and spraying a fine mist into the air, creating a cloud-like image. It is an installation by the city of Zurich, inteded to bring […]
