Ammonia (NH3) is an air pollutant mainly emitted from the agriculture sector with an increasing part from traffic that is highly uncertain in urban areas. NH3 is a highly reactive gas capable of forming fine particulate matter which are harmful for human health. Monitoring NH3 is therefore essential, especially in urban areas such as in […]

Over the past decade, significant progress has been made in improving the monitoring of the Earth’s atmosphere and our understanding of the impact that human activities have on air pollution. IASI/Metop is one of these satellite instruments capable of mapping the chemical composition of the atmosphere globally and in near-real time. In a recent study, […]

In the boreal spring of 2020, worldwide measures for curbing the spread of the COVID-19 virus have led to unprecedented and abrupt lockdowns in transportation and industry. They have led to sharp decrease of emissions of anthropogenic pollutants that induced significant changes in the composition of the atmosphere from city to hemispheric scale. Using an […]
