Smog over Krakow gave up to a height of 100 meters. Above this anti-contention, we clean up – the results of research conducted with the use of a social tool in the capital of Małopolska.
“We know what the air quality looks like at ground stations, but we didn’t know how it changes with increasing altitude. The research that leads us to nearly two years shows that smogging up to 100 meters above Krakow. Above this side, the air becomes cleaner “- told PAP the co-author of the study, Dr. Eng. Jakub Bartyzel, a physicist from the AGH University of Science and Technology.
He also drew attention to the influence of wind on air quality. “The city is situated in a valley. Therefore, the wind blows overcoming the overcoming and is not able to pronounce smog from the city. Such a situation occurs, especially when in the mountain wind, which is with the feeling that you are not going up “- naked clinics, from AGH University of Science and Technology and added: If we wanted to have a place for a building, we could maintain the possibility of breathing, regardless of the location, we would have to have over 100 meters high “.
According to popular opinion, the stronger the wind, the better the quality. Studies have shown that, however, on the installation of a country, where wind, wind, it can be quite the opposite – in the valleys of cities, the so-called cold air pools, air quality assurance.
Air research has been using the balloon for two years now with the AGH and the Institute of Meteorology and Water Management. The Max Planck Institute for Biogeomy from Germany is also working on the first chemicals.
For the year of the future lookout, which will always be in Krakow, whenever they can in the weather, skilful methods that may have new methods of assessing concentrations (CO2, CH4 and H2O), conditions for selection outside the office of the disappointed, and meteorological devices.
As a standard, the Krakow sightseeing balloon hovers about 150 meters above the city center, and during flights it rises up to 280 meters. The balloon is certified by the European Aviation Safety Agency.
The balloon is also up-to-date on air quality – with the help of clouds on time, changing colors. Green color means refresh, red color – bad quality refresh. The data shown comes from the reference station of the Chief Environmental Inspectorate in Dietla Street, which is held in a balloon and shows the quality status in the center of Krakow.
The Krakowscy are planning further balloon test workshops. According to the announcements, the measurements were also to remain at night, when the PM10 dust care changed. Researchers will try to fold between different producers in the suspended dust. with incl. In this city or in this city, it comes from the city or as equated to the city.
This research is possible thanks to the possibility of establishing cooperation with scientists from France (French National Research Center), which may be facilitated by using technical assistance in Paris. The new instrument for these tests has already been installed in the balloon.
Thanks to the observation balloon, AGH UST scientists also conduct 24/7 measurements of caution and methane in the atmosphere every month. Their projects “Work under the EU program” CO2 to the network of tools from the “Copernicus” system. (PAP)
