Into Using a method developed by NASA and illustrated on Atmospheric Measurement Techniques satellites around the Earth will soon be used to check the health of the plants. The system has experienced particularly used data from the European Metop-A satellite in orbit at an altitude of hundreds of kilometers from the Earth’s surface, and exploits the physical phenomenon called fluorescence which photosynthesis takes place when the plant makes light of a certain length d ‘wave, can not be perceived by man but measurable by the instruments. Now researchers have managed to refine the measurement using an algorithm to such an extent as to obtain high-density maps’ of the woods, so it ‘can also occur in that period of growth and’ greater. For example, and ‘was found that the Midwest of the United States is now one of the most’ productive for plants of our planet.
