a EICO minus MEIC from January 2019 to December 2020; (b) EICO minus EDGAR from January 2019 to December 2020. c EICO minus MEIC during the four high emission months of January and December in both 2019 and 2020; and (d) EICO minus EDGAR during the four high emission months of January and December in both 2019 and 2020. Spatial sampling of three cases according to EICO, blue are grids where EICO is >9 µg m-2 s-1, red are grids where EICO is between 6 µg m-2 s-1 and 9 µg m-2 s-1, and orange are grids where EICO is <6 µg m-2 s-1.
