Short Name:
OCO3_L2_Standard

OCO-3 Level 2 geolocated XCO2 retrievals results, physical model VEarlyR (OCO3_L2_Standard) at GES DISC

The Orbiting Carbon Observatory -3 (OCO-3) was deployed to the International Space Station in May, 2019. It is technically a single instrument, almost identical to OCO-2. OCO-3 "Early" version is an expedited version intended for provisional familiarizing with the instrument spectral and calibration properties. The Orbiting Carbon Observatory is the first NASA mission designed to collect space-based measurements of atmospheric carbon dioxide with the precision, resolution, and coverage needed to characterize the processes controlling its buildup in the atmosphere. OCO-3 incorporates three high-resolution spectrometers that make coincident measurements of reflected sunlight in the near-infrared CO2 near 1.61 and 2.06 micrometers and in molecular oxygen (O2) A-Band at 0.76 micrometers. The three spectrometers have different characteristics and are calibrated independently. This dataset contains geolocated retrieved state vectors with CO2-column averaged dry air mole fraction using 3-band full physics retrieval (includes Full physics algorithm results that provide details of algorithm performance). The dataset also contains atmospheric and geophysical properties collected during each spacecraft orbit. This product typically includes more than 4,000 retrievals of the concentration of atmospheric carbon dioxide in cloud-free scenes, as well as surface pressure, surface albedo, aerosol content and water vapor and temperature profiles.
