Satellites are also used to monitor and fight climate…

Temperatures are constantly rising, natural disasters are increasing in their virulence, droughts stretch longer and longer, there is less and less ice at the poles, and more and more lands and their populations are exposed to the risk of dying of thirst.

Climate change is a reality that hardly anyone in the scientific community denies any longer. Therefore, the world’s powers are cooperating with several research institutions and making a huge effort to study and fight this global phenomenon.

One way to monitor and fight climate change is to send dedicated satellites into space, in order to monitor from above the changes occurring at ground level. One of them is the ESA satellite SMOS.

SMOS is a small satellite that has been analysing soil moisture and ocean salinity since 2009. Surprisingly enough, these two parameters are intrinsically linked to climate change. On the one hand, knowing how the Earth “breathes” allows us to know the fertility of the fields, or how forests sequester carbon dioxide. On the other hand, the amount of salt in the sea plays a fundamental role on the research of ocean currents and how these vary according to climate.

Copernicus Sentinels help to monitor climate change from space.. Among other things, they send images and data of the Earth; this will allow to obtain detailed measurements of ozone, nitrogen dioxide, sulphur dioxide and other air pollutants.
