Fig. 4: Ratios between CO emissions computed due to adjustments of input variables and the original EICO of the whole year 2020 with the ranges of fractional changes (inside parentheses).

Calculated CO emissions when (a) TROPOMI CO plus 30% (1.03–1.26); (b) a priori emission of CO plus 30% (1.06–1.27); (c) TROPOMI HCHO plus 40% (0.98–1.33); (d) wind data changed to 900 hPa (0.82–1.21); (e) TROPOMI CO minus 30% (0.78-0.98); (f) a priori emission of CO minus 30% (0.76-0.95); (g) TROPOMI HCHO minus 40% (0.93–1.13); and (h) wind data changed to 800 hPa (0.82-1.28).
