Introduction of new features in C3S seasonal forecast plots and data (Jan/2023)

With the release of January 2023 C3S seasonal forecast the following changes have been introduced:

  • New observational dataset in SST indices (NINO, IOD) plots: ERA5 SST has been introduced to substitute NCEP OIv2. This affects all new plots created from January 2023, specifically all new real-time forecast plots released but also the updates with new observations to previously released plots: from April/2022 for NINO indices (March/2022 in the case of C3S multi-model and ECCC multi-model) and May/2022 for IOD

  • New pressure level (1000hPa) available from UK MetOffice GloSea6 data
