Source Apportionment of Black Carbon Subtypes (char and soot) and Direct Radiative Forcing Effects of Black Carbon from Different Sources

Using the provided data, source apportionment of char and soot can be achieved based on ¹⁴C; combined with multiple linear regression, the MAE of char and soot from different sources can be obtained. The results are then input into the model to derive the direct radiative forcing effect of black carbon. The char/soot data from Zhoushan, Lin'an and Jinsha are also included.
