NASA Suomi NPP Satellite Reveals Images of Earth's Vegetation (Video)

The picture doesn't look like much. In fact, it seems to show an image that we're all familiar--planet Earth with its well-known continents. Yet this picture is far more than it seems, and is actually the triumph of NASA's Suomi NPP satellite. After collecting a year's worth of data, the satellite has produced a vivid depiction of worldwide vegetation with these new pictures, revealing how areas have changed over time.
Suomi NPP's mission is to help monitor and predict the course of long-term climate change and short-term weather conditions. The satellite is actually part of the Earth Observing System (EOS), which consists of a series of satellites that reveal critical insights into the dynamics of the entire Earth system, including our planet's clouds, oceans, vegetation and ice. In fact, Suomi NPP serves as a bridge between EOS satellites and the forthcoming series of Joint Polar Satellite System (JPSS) satellites. In this particular case, though, Suomi has focused on the world's vegetation, showing exactly how rainfall patterns have increased or decreased.
The new images show the differences between the green and arid areas of Earth as seen in data from the Visible-Infrared Imager/Radiometer Suite, or VIIRS, instrument aboard Suomi NPP. VIIRS detects changes in the reflection of light, producing images that measure vegetation changes over time.
This data is important. It will be incorporated into many Normalized Difference Vegetation Index, or NDVI-based products and services. This vegetation index measures and monitors plant growth, vegetation cover and biomass production. In addition, it represents the photosynthetic potential of plants, which means that it's crucial for developing models that deal with calculating global temperatures and the impact of climate change. In addition, it allows researchers to better see the effects of drought in certain areas.
