| 20220115 | 20230101 | Change version of CAMS-GLOB-ANT anthropogenic emission version for CO2 and CH4 in 2023 from v5.1 to v5.3, as there was no emission upgrade for 2023 in v5.1 and the two versions are very similar. Both are based on EDGARv5. The main difference between the two version is change of seasonal cycle for agriculture sector in CH4. |
| 20231213 | 20240101 | CAMS-GLOB-ANT v5.3 anthropogenic CH4 emissions from 2023 are used in January 2024. Note that the difference in the budgets between 2023 (377.14 TgCH4) and 2024 (378.31 TgCH4) is very small and CY47R3 will be superseded by CY48R1 early 2024. |
