High-tech air measurement in Hamburg

A new measuring method is being tested on the Elbe River, which can be used to measure pollutants in the air.

As a result of the pandemic, air quality has improved worldwide, as can be seen from satellite images. But if a company from Hamburg has its way, it won't soon be necessary to climb into earth orbits to obtain information on nitrogen oxides, carbon dioxide, particulate matter, etc.  The company Breeze Technologies has installed 35 sensors in Altona, which cover the district in a network and take measurements there. The size of the entire area is 14 square kilometers, making it the largest of its kind - worldwide. A further 20 sensors are also distributed over the rest of the Hanseatic League city area. This makes it possible to provide daily and real-time information on air values.  But the measuring stations that have been put into operation so far are only the beginning, according to Breeze Technologies: "In the future, we want to be able to say for every street, for every block in the city quarter, how the air quality there is developing over time, so that we can then decide on intelligent measures for air pollution control.
