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

OCO-2 Gridded bias-corrected XCO2 and other select fields aggregated as Level 3 daily files V4 (OCO2GriddedXCO2)
atmosphere NASA GES_DISC Level 3
In plain English

What it measures. Daily gridded maps of carbon dioxide concentration in the air, expressed as the average amount of CO2 in a column of the atmosphere.

How it's made. Created from the OCO-2 satellite's bias-corrected carbon dioxide measurements by smoothly filling in between observations using a statistical interpolation method.

How & where you'd use it. Helps researchers track where carbon dioxide is concentrated and how it shifts over time, supporting studies of the carbon cycle and greenhouse-gas trends.

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.
