Carbon dioxide in the air, gridded daily (OCO-2)

OCO-2 Gridded bias-corrected XCO2 and other select fields aggregated as Level 4 daily files V3 (OCO2GriddedXCO2)
atmosphere NASA GES_DISC Level 4
In plain English

What it measures. Daily maps of carbon dioxide concentration in the air (as a fraction of all the air molecules) plus a few related variables.

How it's made. Created by smoothing and gap-filling the OCO-2 satellite's bias-corrected CO2 measurements onto a daily grid using a statistical interpolation method.

How & where you'd use it. Helps researchers track where carbon dioxide builds up and how it moves, supporting climate and carbon-cycle studies.

Official description

Gridded carbon dioxide mole fraction (XCO2) and other select variables created by applying local kriging (also known as optimal interpolation) to daily aggregates of Orbiting Carbon Observatory (OCO-2) bias corrected data. This is the latest version of this collection. The DOIs assigned to previous versions, which are no longer available, now direct to this page.
