Large CO(2) Emitters as Seen From Satellite: Comparison to a Gridded Global Emission Inventory

Using the multiyear archive of the two Orbiting Carbon Observatories (OCO) of NASA, we have retrieved large fossil fuel CO(2) emissions (larger than 1.0 ktCO(2) h(−1) per 10(−2) square degree grid cell) over the globe with a simple plume cross‐sectional inversion approach. We have compared our resul...

description Using the multiyear archive of the two Orbiting Carbon Observatories (OCO) of NASA, we have retrieved large fossil fuel CO(2) emissions (larger than 1.0 ktCO(2) h(−1) per 10(−2) square degree grid cell) over the globe with a simple plume cross‐sectional inversion approach. We have compared our results with a global gridded and hourly inventory. The corresponding OCO emission retrievals explain more than one third of the inventory variance at the corresponding cells and hours. We have binned the data at diverse time scales from the year (with OCO‐2) to the average morning and afternoon (with OCO‐3). We see consistent variations of the median emissions, indicating that the retrieval‐inventory differences (with standard deviations of a few tens of percent) are mostly random and that trends can be calculated robustly in areas of favorable observing conditions, when the future satellite CO(2) imagers provide an order of magnitude more data.
