OCO-2 Level 2 bias-corrected XCO2 and other select fields from the full-physics retrieval, Forward processing V11.3 (OCO2_L2_Fwd_FP_11.3)

Version 11.3 is the current version of the data set.

The OCO-2 Full-physics Forward processing files contain bias-corrected XCO2 along with other select fields aggregated as daily files.

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.
