About Nitrogen Dioxide
Nitrogen dioxide is the chemical compound with the formula NO ₂. It is one of several nitrogen oxides. NO ₂ is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year which is used primarily in the production of fertilizers.

Coronavirus: lock have continued to be below European pollution press
There is enough data to be confident in the observed Changes in
the New data, the improvement of air quality in Europe - a by-product of the coronavirus crisis.
The maps on this page to keep track of Changes in Nitrogen Dioxide (NO2) - a pollutant that comes mainly from the use of fossil fuels.
Lockdown policies, and the resulting reductions in economic activity have seen emissions take a steep dive.
The cards were produced by The Royal Netherlands Meteorological Institute (KNMI).
The Dutch Met Office leads the Tropomi instrument on the Copernicus Sentinel-5P satellite monitors A Number of atmospheric gases, including NO2.
The comparisons made are for the concentrations in the air from 14 to 25 March, with the monthly average concentrations for March 2019.
How France was on the search a year ago,You need to average in, as a rule, a 10-day, a good moment recording, says Dr. Henk Eskes of KNMI: "You can't just One Day of data," he told Bbc News .
"There is a lot of variability in NO2 from day to day. And that is not real variability; it is a measurement artifact, But it is simply due to Changes in The Weather . So, if The Wind Changes direction or The Wind speed Changes , or the stability of the Boundary Layer Changes - You get different Readings . "
the combination of data for The 10 days irons, much of this variability to see and it allows us, the impact of Changes due to human activity.
Sentinel-5P (S5P) published maps so far, China and Italy . New from Italy on this site, again shows the significant declines in The North of the country, where the Covid-19-the outbreak was in its most difficult.
But there are also new cards from France, Spain and Portugal.
in Other countries in Northern Europe will be closely monitored, including the Netherlands and the UK - But the KNMI have observed, scientists have a greater variability due to the changing weather conditions.
The deadline to see The Dip concentrations in the UK is also pretty short. Britain went into the device after some of their Western European neighbours.
New measurements will judge from This Week help You to, The Changes in Nitrogen Dioxide over the United Kingdom.
Italy in lockdown in the Northern Italian powerhouse, what it looked like Last YearSentinel 5P is part of the EU's Copernicus fleet of The Earth observer, managed by the European Space Agency .

It is only the individual instrument Tropomi leads. This is a spectrometer that observes the reflected solar light from The Earth , the analysis of the in many different colors.
in this case, it is The Presence detect in the atmosphere of A Number of trace gases such as Nitrogen Dioxide , ozone, formaldehyde, sulphur dioxide, methane, carbon monoxide, and aerosols (tiny droplets and particles).
the scientists combine S5P data with A Number of atmospheric transport models to the understanding of The Observations .
"For China, I think we now have very solid results, and that's partly because we have a long time already. And we have the first signs of a recovery, as people in China start to have to go Back To work. We closely follow the development to see if the NO2-concentrations returned to pre-coronavirus levels," says Dr. Eske told Bbc News .
