The inconsistency between GCAM v7 and GCAM-China v6

[licaicaicumt]

Hello, everyone! I have run the default scenarios using GCAM v7.0 and GCAM-China v6, and I have some questions regarding the alignment between the two models. Specifically:

1. First, regarding the historical data (as shown in Figure 1), there are significant differences in the historical data of “primary energy consumption by region”, especially for “oil” between GCAM v7.0 and GCAM-China v6. There are also discrepancies in other energy type. What causes these differences? How can I unify the historical data between the two models?
2. For the China region (as shown in Figure 2), GCAM includes both “traditional biomass” and “biomass”, while GCAM-China only contains “biomass” at the national level and “traditional biomass” at the provincial level. What are the differences between “traditional biomass” and “biomass”?
3. Following up on question 2, I intended to verify whether the sum of provincial data equals the national-level data. However, I found that in GCAM-China, the national-level fuel options are “oil, natural gas, coal, and biomass”, while the provincial-level options are “nuclear, wind, solar, and traditional biomass”. These two sets of fuel options do not overlap at all. How can I obtain a complete list of fuels?

Any insights would be helpful to me. Thank you.
