Sulfur dioxide (SO2)
Sulfur dioxide (SO2) is a major air pollutant, the largest sources are the combustion of fossil fuels and volcanic eruptions. The corrosive gas not only adversely affects the human health and environment, but also impacts air traffic and climate. Timely detection of SO2 helps to minimize volcanic hazards and indicates where risky gas and ash concentrations are occurring.

Ozon (O3) - Antarctia
Ozon-Gehalt der Atmosphäre. Während das Ozon in der Stratosphäre vor harter UV-Strahlung schützt, schädigt das bodennahe Ozon die Atemwege. Die Animation zeigt das gesamte Ozon in der Atmosphäre. Gut zu erkennen, die dynamischen Transportprozesse in der Stratosphäre, bzw. die Entwicklung des Ozonlochs über der Antarktis. Die Daten wurden aufgenommen vom TROPOMI Instrument auf dem Sentinel-5P Satelliten und am DLR prozessiert vom Projekt INPULS...

Ozon (O3) - Arktis
Ozone content of the atmosphere. While the ozone in the stratosphere protects against harsh UV radiation, the ozone near the ground damages the respiratory tract. The animation shows the total ozone in the atmosphere. The dynamic transport processes in the stratosphere and the development of the ozone hole over the Antarctic are clearly visible. The data was recorded by the TROPOMI instrument on the Sentinel-5P satellite and processed at DLR by the INPULS project...

Nitrogen Dioxide (NO2)
Nitrogen dioxide (NO2) arises during combustion processes and is, along with particulate matter and ozone, a critical air pollutant.
Nitrogen dioxide attacks the respiratory tract, interferes with biochemical processes and contributes to the acidification of soil and water bodies.

Air Quality Forecast for Central Europe - Nitrogen Dioxide (NO2) – Ground Level
Nitrogen dioxide is an air pollutant that negatively affects human health, primarily because it irritates the mucous membranes of the respiratory organs and the eyes. NO2 is emitted during combustion processes in industry, transportation, power plants and households, but also during forest fires and thunderstorms. As a precursor substance for ground-level ozone formation it contributes to radiative forcing as a climate-relevant gas. Because of its bearing on health and the climate, the threshold values for NO2 are regulated by the Air Quality Guidelines for Europe.

Air Quality Forecast for Central Europe - Ozone (O3) - Ground Level
In the troposphere and at ground level, ozone is an air pollutant with harmful effects on human health. For that reason national and international legislation specify continuous monitoring of ozone concentration in the ambient air and the issuing of information or warnings to the public if threshold values are exceeded. Ozone is not directly emitted; it is exclusively produced from precursor substances like NO2 in combination with solar radiation.

Air Quality Forecast for Central Europe - Particulate Matter (PM10) - Ground Level
As tiny liquid and solid particles in the atmosphere, aerosols are important components of Earth’s climate system. Among other functions they control the global energy balance and affect the water cycle. In the form of fine dust they are harmful to human health.
Fine particulate matter is emitted in large quantities in cities and conurbations during combustion processes associated with transport, industry, heating and wood burning. Particulate matter forecasts provide crucial information for patients at risk of respiratory and heart disease.

HNO3
Nitric acid (HNO3) is one of the most important nitrogen compounds and is formed in the atmosphere by the chemical conversion of nitrogen oxide compounds. Nitric acid contributes to acid rain and leads to leaf necrosis and soil leaching.
