Weather conditions for each carbon sounding (OCO-2)

OCO-2 Level 2 meteorological parameters interpolated from global assimilation model for each sounding, Retrospective Processing V11r (OCO2_L2_Met) at GES DISC
atmosphere NASA GES_DISC Level 2
In plain English

What it measures. The weather conditions (such as temperature, pressure, and humidity) matched to each individual carbon-dioxide measurement the satellite took.

How it's made. Not measured by the OCO-2 satellite itself but interpolated from a global weather model and paired with each of the satellite's carbon soundings.

How & where you'd use it. A supporting input that gives the atmospheric context needed to accurately interpret OCO-2's carbon-dioxide readings, mostly used alongside the main CO2 products.

Official description

Version 11r is the current version of the data set. Older versions will no longer be available and are superseded by Version 11r. 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 meteorological parameters interpolated from global assimilation model for each sounding.
