Fig. 3: Temporal variation of net methane (CH4) fluxes in the Tibetan alpine permafrost region based on contemporary data (black and gray lines) and future projections under SSP1-2.6 (green dashed line), SSP2-4.5 (dark green solid line), SSP3-7.0 (orange solid line), and SSP5-8.5 (blue dashed line).
From: Spatiotemporal patterns of methane fluxes across alpine permafrost region on the Tibetan Plateau
The black solid line represents the net CH4 fluxes during contemporary period (1989-2018), simulated using China Meteorological Forcing Dataset (CMFD). The gray solid line represents the net CH4 fluxes during the contemporary period from 1989−2014, simulated using GCMs outputs. The colored solid and dashed lines represent multi-model mean CH4 emissions under four SSP scenarios, and the shaded areas indicate the standard deviation of CH4 emissions across multiple models. The mean and standard deviation of the multi-model data for the period 2071−2100 are shown in the right panel.
