The European Union’s Earth Observation program, Copernicus, provides accurate, timely and easily accessible information regarding our planet and its environment. A key component of the program is the Sentinel family of satellites, developed by the European Space Agency (ESA). There are currently five missions in orbit comprising of 8 Sentinel satellites, which have objectives ranging from measuring sea levels to monitoring air pollution. One of these missions is Sentinel-3, (see figure 1), which has a primary focus to monitor the ocean and coastal areas. Currently, there are two Sentinel-3 satellites in orbit, with the first, Sentinel-3A, launched in February 2016 followed by Sentinel-3B in April 2018. A key payload carried by Sentinel-3 is the Ocean and Land Colour Instrument (OLCI), an …

On Friday 13 October 2017, the Sentinel-5P satellite bearing the Dutch TROPOMI space instrument was successfully launched from Plesetsk, in Siberia. From space, TROPOMI will monitor the air quality and distribution of greenhouse gases worldwide. This groundbreaking instrument will strengthen the position of the Netherlands as a supplier of high-end aerospace instruments.   TROPOMI, which stands for TROPOspheric Monitoring Instrument, is a satellite instrument that will carry out measurements on the troposphere, the lowest layer of our atmosphere. It is capable of measuring air quality to an unprecedented degree of accuracy, and of identifying carbon monoxide, methane, nitrogen oxide, and ozone, among other things. “The launch of TROPOMI means a new standard is being set in the field of atmospheric research,” …
