Bias corrected and Warn Level not applied. B) OCO2 Lite Product Column-Averaged Dry Air Mole Fraction of Carbon Dioxide, one month (July/01/2015 - July/31/2015) aggregate and grid of 31xdaily files of "OCO2_L2_Lite_FP_V7" data type ,variable "XCO2", in parts-per-million (ppm). Bias corrected and Warn Level not applied.

The OCO-2 Lite 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.

The software uses an iterative, non-linear retrieval technique (optimal estimation). After the retrieval process has converged, the software performs an error analysis. The products of the software include all quantities needed to understand the information content of the measurement, its uncertainty, and its dependence on interfering atmospheric properties.
