Forest Gain Loss
This model show the forest gain and loss models. It also looks at the vegetation index.
Today, only 4 billion hectares are left. The world has lost one-third of its forest – an area twice the size of the United States.
Using radar data from the European Space Agency’s Sentinel-1 satellites, which cover the tropics every 6 to 12 days. The long wavelength radio waves can also penetrate smoke and haze, providing insight on forest loss that is occurring in areas that are otherwise shrouded.
We also use fire detection satellite data from two sensors viz. MODIS and SNPP. The Terra MODIS instrument acquires data twice daily, as does Aqua MODIS. Therefore, four daily MODIS observations are available for forest fires.
