A deeper analysis for Munich The COVID-19 pandemic has infected about 13 million people and claimed more than 550 thousand deaths worldwide by 14 July 2020. It has been reported in research that high air pollution may be “one of the most important contributors to deaths from COVID-19”. Studies show a positive correlation between particulate […]

For the first time in human history, the technology exists today to monitor every single emission – of every city, every airport, every harbour, every street, every factory, industry park and wildfire. At our disposal are tools to hold those accountable that do not adhere to environmental commitments and those using their resources lavishly.

Hawa Dawa has been producing measuring devices for comprehensive air quality measurement for several years.
In the following, we would like to try to present the technical complexity of air-pollutant measurement in a simple way and to give indications on this basis, which limits the individual devices and methods have.

In general all graphs show that the mean NO2 concentration after the lockdown date has decreased – at some stations the effect is larger than at others. Concentration peaks with similar amplitudes, compared to before the lockdown, persist. The overall patterns would require a more detailed analysis of the locations e.g. considering mobility behaviour.

In the days of Covid-19, “air quality” is a topic in the media, too. Municipalities are often pioneers in pushing for improvements. Decisions must be made in complex social contexts and measures must be integrated into larger plans. Here’s an interview with Karim Tarraf, CEO of Hawa Dawa, in which he comments on the following topics:
How can the increasing importance of air quality data be explained?
Why are the available measurements and data usually insufficient?
What does cooperation with municipalities look like?

Cities worldwide have been imposing lockdowns due to coronavirus, leading to traffic reductions and related to that, less NO2 pollution. The strength of the effect is not the same everywhere, being dependent on a number of variables, such as pollution levels and amount of traffic before the lockdown at the particular location, fleet composition, weather conditions and topography and urban architecture.

I have recently heard people uttering disappointment regarding the rather small effect they have observed at official measurement stations in Munich during the time of the lockdown due to the coronavirus. Looking at the raw hourly measurement traces at different locations in and around Munich, we can see a very clear drop during the initial phase of the lockdown, with concentrations coming up again after that. So we decided to take a deeper look. We considered impacts from weather conditions, season-specific influences as well as mobility behaviour.
