and ground-level ozone (O?) levels over China in February were 20-30% down on the average February levels expected at this time of year (drawing on data from 2017-2019). Air pollution is the biggest environmental health risk in Europe, with the problem greatest in cities, according to the EEA. In early March, ESA also said PM2.5

The cores, which provide a historic record between 1957 and 2017, provide evidence that levels of these chemical pollutants have shown a marked increase in the remote snowpack of Antarctica over the last few decades. The Montreal Protocol certainly provided huge benefits and protection to the ozone, the climate and to us all.

The Tropomi spectrometer on board the European satellite Sentinel-5p has been conducting measurements since 2017. We also measure gases that are responsible for the formation of ground-level ozone, which is very harmful to human health,” said Schreier. The latter is work in progress. The five-year project will run until 2021.

Due to its climate and indirect health impacts (methane is a precursor for ozone which is an air pollutant that damages human health and crops), methane mitigation has recently become a global policy priority. These updates resulted in a total methane emission estimate more than five times larger than reported emissions.

level over 2013-2017, improvements attributed to measures targeted at lowering emissions from coal-fired power stations and industries, as well as more stringent targets for vehicle emissions and fuel quality. The NOx gases are chemically reactive, and so tend to contribute to the formation of other pollutants such as ozone and PM2.5.

These VOCs contribute to ground-level ozone and smog, which can cause respiratory issues and environmental damage. For example, during Hurricane Harvey in 2017, the EPA temporarily lifted RVP restrictions to prevent supply shortages. RVP is a gauge of how easily gasoline evaporates at high temperatures.

Part of the government’s Automatic Urban Monitoring Network, the reference station has monitored ozone, NOx and fine particulates since 2017. Until recently, there was just a single continuous air quality monitoring station in or near Northampton.
