Satellites hold the key to climate monitoring
Certain climate parameters, like reflected solar flux and infrared radiation emitted by Earth and its atmosphere, can only be measured from space. These are key data for understanding how the climate system works.
Satellites have therefore become essential tools as a result of their ability to acquire highly precise measurements all over the planet, complementing readings taken on the ground.
Systematic global data
Satellites deliver uniform (acquired by the same instrument all over the globe), repetitive (over long time-series) data acquired automatically for climatology research.
The value of space to climate research is therefore clear and is driving the space policy that CNES is pursuing at European and international level.
