The CAMS forecast 46R1 o-suite (experiment h9sp) was started on 2019-01-01 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.
• 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.
