Fig. 2: Difference between global CO-based fire CH4 emission estimates and global fire emission model results by month and latitude.
From: Enhanced CH4 emissions from global wildfires likely due to undetected small fires
a Monthly fire CH4 emissions from CO-based (red curve) estimates and average estimates of 4 fire emission models (green curve) and their difference (shaded gray region) averaged between 2003 and 2020. The error bars represent one standard deviation due to interannual variation from 2003 to 2020. b Differences between CO-based CH4 emission estimates and those of four models by month and latitude.
