This animation, using data from the Copernicus Sentinel-5P satellite, shows the nitrogen dioxide emissions from 20 December 2019 until 16 March 2020 – using a 10-day moving average. The drop in emissions in late-January is visible, coinciding with the nationwide quarantine, and from the beginning of March, the nitrogen dioxide levels have begun to increase.

New data from the Copernicus Sentinel-5P satellite reveal the decline of air pollution, specifically nitrogen dioxide emissions, over Italy. This reduction is particularly visible in northern Italy which coincides with its nationwide lockdown to prevent the spread of the coronavirus.
The animation shows the fluctuation of nitrogen dioxide emissions across Europe from 1 January 2020 until 11 March 2020, using a 10-day moving average. These data are thanks to the Tropomi instrument on board the Copernicus Sentinel-5P satellite which maps a multitude of air pollutants around the globe.
Claus Zehner, ESA’s Copernicus Sentinel-5P mission manager, comments, “The decline in nitrogen dioxide emissions over the Po Valley in northern Italy is particularly evident.
“Although there could be slight variations in the data due to cloud cover and changing weather, we are very confident that the reduction in emissions that we can see, coincides with the lockdown in Italy causing less traffic and industrial activities.”
Josef Aschbacher, ESA’s Director of Earth Observation Programmes, says, “Copernicus Sentinel-5P Tropomi is the most accurate instrument today that measures air pollution from space. These measurements, globally available thanks to the free and open data policy, provide crucial information for citizens and decision makers.”
The coronavirus disease (COVID-19) was recently declared a pandemic by the World Health Organisation, with more than 125 000 current cases of the disease reported globally. In Italy, the number of coronavirus cases drastically soared making it the country with the largest number of cases outside of China.
In an attempt to reduce the spread of the disease, Italy’s Prime Minister Giuseppe Conte announced a lockdown of the entire country – closing schools, restaurants, bars, museums and other venues across the country.
The Sentinel-5 Precursor – also known as Sentinel-5P – is the first Copernicus mission dedicated to monitoring our atmosphere. The satellite carries the Tropomi instrument to map a multitude of trace gases such as nitrogen dioxide, ozone, formaldehyde, sulphur dioxide, methane, carbon monoxide and aerosols – all of which affect the air we breathe and therefore our health, and our climate.
Given the growing importance and need for the continuous monitoring of air quality, the upcoming Copernicus Sentinel-4 and Sentinel-5 missions, as part of the EU’s Copernicus programme, will monitor key air quality trace gases and aerosols. These missions will provide information on air quality, stratospheric ozone and solar radiation, as well as climate monitoring.

Atmospheric carbon dioxide is the most important human-made greenhouse gas responsible for global warming. Oceans assist in removing carbon dioxide from the atmosphere: phytoplankton accumulate carbon dioxide through photosynthesis and their chlorophyll colours the ocean’s waters. Satellites use this colour to measure chlorophyll, which helps scientists to calculate how much carbon dioxide is absorbed or emitted.

Read the full experiment at http://www.stevespanglerscience.com/experiment/instant-freeze-soda-ice It might have happened to you… You put a bottle of soda in the freezer for a few minutes just to get it ice cold. When you take the soda out of the freezer, it’s still a liquid (nothing unusual has happened just yet). However, the second you twist off the cap, the soda instantly freezes! The process is amazing to watch… but it’s a real bummer if you were thirsty (because it’s tough to suck ice out of the bottle). This is a great illustration of how carbon dioxide can lower the freezing point of water. Get some ice, some salt and some plastic bottles of soda water and try this very cool science demo.
