OCO-2 Level 2 geolocated XCO2 retrieval results and algorithm diagnostic information Retrospective Processing V11.2r (OCO2_L2_Diagnostic)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/3ltyel5ppmwb
Version 11.2r is the current version of the data set.
Description
Older versions will no longer be available and are superseded by Version 11.2r. 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.
The OCO-2 project uses the LEOStar-2 spacecraft that carries a single instrument. It 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. This collection encompass various data fields used for diagnostic and pre-processing, including aerosol optical depth, albedo, absorption coefficients, fluorescence, XCO2 uncertainties, averaging kernel, surface type, etc.
