With the release of our June 2023 seasonal forecasts a couple of additions have been made to the offering of the C3S seasonal forecast service:
- New variables for water quantities integrated over the whole atmospheric column (water vapour, cloud liquid water and cloud ice water) are available. Initially, in June 2023, these data variables are available from ECMWF SEAS5, CMCC SPS3.5 and DWD GCFS2.1.
- New verification plots have been added to our C3S seasonal forecasts verification plots page, including correlation for SST-based indices (NINO regions and Indian Ocean Dipole)
Please also note that a "data gap" issue has been documented in our C3S Seasonal Forecast known issues page affecting availability of NCEP CFS2 data for 22/May/2023 (see details for issue G8. in the "Data gaps" table)
