## OCO-2 B10 signal analysis

The OCO-2 "signal" is defined as gridded 10-second-average OCO-2 B10 retrievals minus a CO_{2}reference. All quantities are presented as column-average (pressure-weighted) CO

_{2}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 CO

_{2}analyses, each of which is constrained by traditional

*in situ*measurements:

- CarbonTracker
- Jena
- MACC
- University of Edinburgh
