Fig. 1: Average emission sensitivity derived from FLEXPART simulations and ratios between different sites in 2021 and 2022.
From: CCl4 emissions in eastern China during 2021–2022 and exploration of potential new sources
a, b Average emission sensitivities for ZJU (blue triangle) and SHH (blue dot) sites. c, d for the GSN (blue cross) site. e, f Ratio of the average emission sensitivity of ZJU and SHH stations to that of the GSN site. The area framed by the bold black line is the target area (provincial names shown in Supplementary Fig. 1) for the inversion. ZJU, Zhejiang University; SHH, Shanghuang; GSN, Gosan. A larger domain is shown in Supplementary Fig. 2.
