The CAMS analysis o-suite in Atos (experiment heus running at tco399, L137) is a continuation of analysis osuite (experiment hlkx) running on the Cray. Switchover between Atos and Cray experiments on 24 October 2022. Main features are:
- IFS cycle 47R3 (suite running from Atos).
- IASI CH4 and CO2 assimilation (extended to extratropical latitudes; to avoid assimilation over antarctica, data is blacklisted south of 60S).
- New CAMS-GLOB-ANTv5.1 anthropogenic CO2 and CH4 emissions (monthly mean files) based on EDGARv5.
- Roedenbeck et al. (2013) CO2 air-sea monthly fluxes for 2019 (Jena-CarboScope v2020 based on SOCAT data).
- GFAS v1.4 biomass burning emissions.
- CO2 and CH4 initial conditions from hlkx (15 September 2022).
- Long 5-day forecast is run at single precision as the operational NWP and CAMS air quality forecast.

Changes introduced during production affecting the quality of the products
| real date | exp date | description of change |
| 2022-10-18 | 2022-10-15 | Change in fetchobs to use new version of emissions. Note the experiment started on 15 September from hlkx but used the old version of the observations. So there will be inconsistencies on the version of observations used between hlkx and heus during period 2022-09-15 to 2022-10-14. |
