Topic 2d – Part 1: Air quality, NO2, CO & the ozone layer
Satellites can measure lots of different sources of atmospheric pollution, such as Nitrogen Dioxide, Ozone, Carbon Monoxide and Particulate Matter. And from these measurements, data products can be produced. Data products are the end product that is made available to users after the analysis of the satellite measurement data or forecast system modelling, for example, is complete.
Data products are extremely important for a range of different users, particularly in order to manage air quality as it has enormously negative effects on human and environmental health.
In this video Dr Mark Parrington talks about data products at CAMS, how satellite data is validated, and looks at three examples of a data product.

Interactive Apps
Explore global Nitrogen Dioxide and Nitrous Oxide data in 3D with this interactive globe. Toggle the data sets on and off using the check box in the workbench located on the left side of the screen. You can also use the tools on the right side of your screen such as “toggle splitter” to view and compare different data layers at the same time. You can also change the base map and map view by clicking on the map icon on the top right of the screen.
The satellites featured in this topic are as follows:
You can also use the drop-down menu in the app to view these satellites.

CAMS monitors the Antarctic ozone hole in near real-time with satellite observations and model data. The ozone hole in 2017 started to develop in early September, slightly later than in most years since 2002
