The latest 2.5 years of Biosphere data with date annotations.
Constantly updated data visualization of the Earth's Biosphere
By monitoring the color of reflected light via satellite, scientists can determine how successfully plant life is photosynthesizing. A measurement of photosynthesis is essentially a measurement of successful growth, and growth means successful use of ambient carbon. This data visualization represents five years' worth of data taken primarily by Suomi NPP/VIIRS satellite sensors, showing the abundance of life both on land and in the sea. In the ocean, dark blue represents warmer areas where there is little life due to lack of nutrients, where yellow and orange represent cooler nutrient-rich areas. The nutrient-rich areas include coastal regions where cold water rises from the sea floor bringing nutrients along and areas at the mouths of rivers where the rivers have brought nutrients into the ocean from the land. On land, green represents areas of abundant plant life, such as forests and grasslands, while tan and white represent areas where plant life is sparse or non-existent, such as the deserts in Africa and the Middle East and snow-cover and ice at the poles.
Colorbar for the Normalized Difference Vegetation Index (NDVI) land cover data. Shades of brown depict little to no vegetation (for example, the Sahara Desert), whereas deep green are large amounts of vegetation (for example, the South American Rainforest).
Colorbar representing the Ocean's chlorophyll. Blues down to violet are areas with little to no chlorophyll. Green to yellow indicate high chlorophyll concentrations or other color dissolved organic materials.
