Fig. 3From: The potential of a constellation of low earth orbit satellite imagers to monitor worldwide fossil fuel CO2 emissions from large cities and point sourcesCumulative distribution of posterior uncertainty for 3 h mean emissions over one year for four cities with different annual budget of CO2 emissions in INV-annual. The y-axis indicates the number of 8:30–11:30 time windows for which the posterior uncertainty of the 3 h mean emission is less than the value of the x-axisBack to article page
