The CAMS analysis o-suite (experiment hlkx running at tco399, L137) was started on 2021-04-01, with an e-suite period from 2021-04-01 to 2021-09-30. Main new feature are:

  • New IFS cycle 47R3  (esuite is based on CY47R3.0  on 20210625) containing prescribed emission/flux changes.
  • 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 initial conditions of e-suite  (20210401) from CAMS re-analysis experiment assimilating the same observations but with smaller biases (hiv2).
  • CH4 initial conditions of e-suite (20210401) from CAMS re-analysis experiment assimilating the same observations but with smaller biases (hiv2).
  • Long 5-day forecast is run at single precision as the operational NWP and CAMS air quality forecast.
