The CAMS analysis o-suite (experiment h72g running at tco399, L137) was started on 2019-09-01, with an e-suite period from 20181128 to 20190831. Main new feature are:
- New IFS cycle 46R1 (branch cxjb_CY46R1_CAMSfixes_GHG)
Inclusion of IASI CO2 in monitoring only as it needs validation first before assimilation.
- The assimilation of CH4 IASI has been extended to extratropical latitudes. To avoid assimilation over antarctica, data is blacklisted south of 60S.
- New CAMS-GLOB-ANTv2.1 anthropogenic CO2 and CH4 emissions from 2018 (monthly mean files).
- Roedenbeck et al. (2013) CO2 air-sea monthly fluxes for 2017 (Jena-CarboScope v1.6 based on SOCAT data).
- CO2 initial conditions of e-suite (20181128) from a cyclic forecast experiment (h6ms) initialised from CAMS CO2 inversion product on 20180831.
- CH4 initial conditions of e-suite (20181128) from o-suite analysis gwx3.

Changes introduced during production affecting the quality of the products
| real date | exp date | description of change |
| 2020-03-10 | 2020-03-06 | Change in GOSAT XCH4 stream from SRON old operational stream (processed up to D*+3) to new fast stream with processing chain operating 4 times a day and providing data within D*+1 (80% KPI). The new fast stream also uses the latest version of CO2 CarbonTracker (2017) resulting in a reduced CO2 extrapolation error and slightly lower XCH4 bias. |

Changes in GHG observations
| real date | exp date | description of change |
| 20200105 | 20200101-20200108 | GOSAT XCH4 data from SRON: Due to an annual transition bug in bias correction, the L2 products delivered between January 1st and 8th have no good quality observations. This bug was fixed at 9th January |
Changes introduced during e-suite phase
| exp date | description of change | |
| 20190827 | bug fix in get_gems_surface (timeint of monthly CO2APF fluxes should be performed every time). Previously the exp was using a fixed date since 20190401 (re-start date) and before date 20190101. | |
