What does OCO-2 satellite do?
The Orbiting Carbon Observatory 2, or OCO-2, is an Earth satellite mission designed to study the sources and sinks of carbon dioxide globally and provide scientists with a better idea of how carbon is contributing to climate change.
Is OCO-2 still active?
February 2019: The OCO-2 (Orbiting Carbon Observatory-2) has been on orbit since 2014, and its global coverage holds the potential to reveal new information about the carbon cycle through the use of top-down atmospheric inversion methods combined with column average CO2 retrievals.
Is OCO-2 active or passive?
OCO-2 uses a combination of active and passive thermal control. Heaters are installed to maintain the internal components and avionics of the spacecraft within their operational range during the night portion of the orbit.
When did OCO-2 launch?
July 2, 2014Orbiting Carbon Observatory-2 / Launch date
NASA successfully launched its first spacecraft dedicated to studying atmospheric carbon dioxide at 2:56 a.m. PDT (5:56 a.m. PDT) on Wednesday, July 2, 2014. Orbiting Carbon Observatory-2 (OCO-2) is NASA’s first dedicated Earth remote sensing satellite to study atmospheric carbon dioxide from space.
How much did OCO-2 cost?

WHO launched Jason 3?
Jason-3 is the follow-on altimetry mission of Jason-2 / OSTM (launch June 20, 2008) led by the operational agencies: NOAA, EUMETSAT, and CNES.
How much did OCO 2 cost?
Why are co2 concentrations higher and more variable in northern latitudes?
Because the northern hemisphere contains much more land than the southern hemisphere – which is mostly covered by ocean – the amount of carbon dioxide in the atmosphere increases overall during the northern winter [2]. The annual variation depends on location.
How much co2 is emitted into the atmosphere by human activity per year?
A net 5 billion metric tons of human-produced carbon remain in the atmosphere each year, raising the global average carbon dioxide concentrations by about 2.3 parts per million per year.
Why is there less CO2 in the southern hemisphere?
Why does the southern hemisphere have less CO2?
In the winter, carbon dioxide levels are at their peak in the northern hemisphere, when there is little plant or phytoplankton growth to offset emissions from human activities and natural sources. At the same time, CO2 concentrations drop in the southern hemisphere, which is bathed in summer sunlight and heat.
Which country puts out the most CO2?
China
CO2 Emissions by Country

What does the Jason-3 satellite do?
Jason-3 is a satellite mission that supports scientific, commercial and practical applications related to sea level rise, ocean circulation, and climate change. Jason-3 follows the current operational altimeter satellite, Jason-2, in maintaining satellite altimetry observations of global sea surface height.
