OCO-2 B10 signal analysis

The OCO-2 "signal" is defined as gridded 10-second-average OCO-2 B10 retrievals minus a CO₂ reference. All quantities are presented as column-average (pressure-weighted) CO₂ dry-air mole fraction (X_CO2) in parts per million (ppm), without averaging kernel corrections. The reference field for the plots on this page is composed of the mean of four different quasi-operational CO₂ analyses, each of which is constrained by traditional in situ measurements:

• CarbonTracker
• Jena
• MACC
• University of Edinburgh

Model samples were computed by Chris O‘Dell based on 10-second averages of OCO-2 B10 retrievals created by David Baker. Subsequent analysis by Andy Jacobson.
