The CAMS forecast 46R1 o-suite (experiment h9sp) was started on 2019-09-01 based on IFS CY46R1. It provides a high resolution forecast (tco1279 L137) in real time, starting from the GHG analysis experiment (h72g) running 4-days behind real time to real and the high resolution NWP analysis. The main features of are:
- IFS branch 46R1.20190910
- Resolution: Tco1279 (9km) and 137 vertical levels
- Initial meteo from NWP OPER stream (early delivery) in order to start the forecast half a day earlier.
The experiment is initialised (with nudging) from the GHG analysis experiment h72g at 00UTC (the coupling with the analysis is done by merging the 4-day forecast from GHG delayed analysis experiment and the cyclic high resolution forecast).
- 5-day forecast from 00UTC
- Coupled to CTESSEL Net Ecosystem Exchange surface fluxes.
- New CAMS-GLOB-ANTv2.1 anthropogenic emissions for 2018 (2019 emissions were not available on time).
- GFAS fire emissions 1 day behind real time.
- Roedenbeck et al. (2013) CO2 air-sea monthly fluxes for 2017 (Jena-CarboScope v1.6 based on SOCAT data).
- Tracer mass fixer: Diamantakis and Agusti-Panareda (2017) with BETA value of 2.
