Earth observation (EO) is the collection, analysis and presentation of data to better understand our planet. Earth observations can be taken at a ground level or acquired from remote sensing platforms such as satellites. From above, satellites can collect data from sites all around the world, including places too remote to visit in person. Satellite images show large areas of the Earth’s surface at one time, making it easier to spot changes and to monitor the health of our planet.
Climate from Space and EO Browser are two online tools that give easy and free access to satellite data from different EO ESA missions.
Climate from Space
The Climate from Space app provides a graphical visualisation of archived satellite data that is already processed and combined to give you an overview of the different climate variables that scientists use to study climate change. It is a powerful visualisation tool specially to see the evolution overtime of variables such as carbon dioxide (CO2), ocean colour, sea surface temperature, and more. The site also gives access to a series of multimedia stories where the climate data is put in context and where you can find useful information about our dynamic planet and the major environmental changes we are facing, from coasts under threat to biodiversity and habitat loss.
EO Browser is an online platform that combines an archive of different Earth observation missions and can be used to find satellite images of any area of interest. Data is freely available.
EO Browser’s Education mode gives the option to access specific satellite data tailored to a selected theme. Themes cover different topics, from agriculture to atmosphere and water bodies.
