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]
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.
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.
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.
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 ]
The Orbiting Carbon Observatory-3 (OCO-3) is a NASA-JPL instrument designed to measure carbon dioxide in Earth's atmosphere. The instrument is mounted on the Japanese Experiment Module-Exposed Facility on board the International Space Station (ISS). [ 4 ]
TEMPO, which is a collaboration between NASA and the Smithsonian Astrophysical Observatory, is NASA's first Earth Venture-Instrument (EVI) mission. [11] [12] The EVI program is an element within the Earth System Science Pathfinder (ESSP) program office, which is under NASA's Science Mission Directorate Earth Science Division (SMD/ESD).
