(a)qCO2 in a northern cap covering latc–90° in latitude and ranging from 0 to 180°W in longitude. Elsewhere, qCO2 is set to 0.
(b) Correction factor to simulated CO2 flux from the surface to reproduce the CO2 line-of-sight column density peak in the latitude profile (Fig. 2).
( * ) Values are low because qCO2 = 0 for latitudes < latc.
