Line Plot from Scientific Research

A priori (thick black line) and a posteriori (shaded areas) emissions north of 30 N for the different regions. CMIP5 and CMIP6 emissions (both including the same biomass burning emissions) are shown with dark and light gray lines, respectively. The regions for which the emissions are optimized are shown as an inset in (d) and reflect the colors used in (a-d).
