Geostationary Carbon Cycle Observatory (GeoCarb) [1] was an intended NASA Venture-class Earth observation mission that was designed to measure the carbon cycle. GeoCarb was to be stationed over the Americas and make observations between 50° North and South latitudes.
Global Ecosystem Dynamics Investigation (GEDI, pronounced / ˈ dʒ ɛ d aɪ /) is a NASA mission to measure how deforestation has contributed to atmospheric CO 2 concentrations. [1] [2] A full-waveform LIDAR was attached to the International Space Station to provide the first global, high-resolution observations of forest vertical structure.
Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) is a 2020s NASA Earth-observing satellite mission to observe global ocean color, biogeochemistry, and ecology, as well as the carbon cycle, aerosols and clouds. [3] PACE is intended to be used to identify the extent and duration of phytoplankton blooms and improve understanding of air quality. [4]
Atmospheric carbon dioxide plays an integral role in the Earth's carbon cycle whereby CO 2 is removed from the atmosphere by some natural processes such as photosynthesis and deposition of carbonates, to form limestones for example, and added back to the atmosphere by other natural processes such as respiration and the acid dissolution of ...
The carbon cycle is a biogeochemical cycle that is important in maintaining life on Earth over a long time span. The cycle includes carbon sequestration and carbon sinks . [ 4 ] [ 5 ] Plate tectonics are needed for life over a long time span, and carbon-based life is important in the plate tectonics process. [ 6 ]
Atmospheric carbon is exchanged quickly between the oceans and the terrestrial biosphere. This means that at times the atmosphere acts as a sink, and at other times as a source of carbon. [2] The following section introduces exchanges between the atmospheric and other components of the global carbon cycle.
Seven years after launching a spacecraft, NASA finally has its hands on a sample from a 4.7-billion-year-old asteroid. Asteroid sample contains water, carbon, NASA says Skip to main content
Orbiting Carbon Observatory-2 (OCO-2) is an American environmental science satellite which launched on 2 July 2014. A NASA mission, it is a replacement for the Orbiting Carbon Observatory which was lost in a launch failure in 2009.
