The orbiting carbon observatory 2 carries and points a three channel imaging grating spectrometer designed to collect high resolution spectra of reflected sunlight within the molecular oxygen a band at 0.765 microns and the carbon dioxide bands at 1.61 and 2.06 microns. here, we describe the oco 2 instrument, its data products, and its. Like oco 2, the oco 3 mission has been designed to collect a dense set of precise measurements of xco 2 with a small footprint. the scientific objective of the mission is to quantify variations of xco 2 with the precision, resolution, coverage, and temporal stability needed to improve our understanding of surface sources and sinks of carbon dioxide on regional scales (≃1000 km by 1000 km.

Abstract. the version 10 (v10) atmospheric carbon observations from space (acos) level 2 full physics (l2fp) retrieval algorithm has been applied to multiyear records of observations from nasa's orbiting carbon observatory 2 and 3 sensors (oco 2 and oco 3, respectively) to provide estimates of the carbon dioxide (co2) column averaged dry air mole fraction (xco2). in this study, a number of. The annual and monthly nadir mode coverage of gosat, oco 2, and oco 3 is presented here as the mean daily sif at 757 nm (sif 757) at a gridded resolution of 0.5 ∘ for visualization. included are soundings from all measurement modes flagged as best and good quality and clear of clouds. After almost a full year in orbit, the xco2 product is beginning to reveal some of the most robust features of the atmospheric carbon cycle, including the northern hemisphere spring drawdown, and enhanced values co located with intense fossil fuel and biomass burning emissions. the orbiting carbon observatory 2 (oco 2) is this first nasa satellite designed to measure atmospheric carbon dioxide. Launched in july 2014, oco 2 (orbiting carbon observatory 2) is an earth observing satellite mission owned and operated by nasa (national aeronautics and space administration), and the successor to oco 1, which was lost due to a launch vehicle failure in february 2009. oco 2 is dedicated to the study of atmospheric carbon dioxide and oxygen.

Abstract. in this study, both the greenhouse gases observing satellite (gosat) and the orbiting carbon observatory 2 (oco 2) xco2 retrievals produced by the nasa atmospheric co2 observations from space (acos) project (version b7.3) are assimilated within the geos chem 4d var assimilation framework to constrain the terrestrial ecosystem carbon flux during 1 october 2014 to 31 december 2015. one. Based on oco 2 sif and tower gpp, several pioneering studies demonstrated strong sif gpp relationship over different biomes [16,17,24–27], suggesting that oco 2 sif has strong.
