1. Brief description: The sea-ice cover data in the BoM re-forecasts is incorrect. The climatological evolution of sea ice in the BoM re-forecats is for 1 January through to early March (62 day re-forecasts) for all start dates. Therefore, the sea ice coverage is wrong in the S2S archive, except for the forecasts that start on or near 1 January 2. Recommendation: It is recommended to not download the BoM sea-ice cover re-forecast data until the correct data has been fully uploaded in the ECMWF S2S data server. There will be an announcement when the problem has been fixed. |

1. Brief description: All data for S2S is required to be encoded in GRIB 2 format with simple packing (to allow faster data processing by users although it results in bigger data volume). The realtime outputs from BoM were unwantedly using grib_jpeg advanced packing until 30 Jan 2020. In contrary, the reforecast have always been encoded correctly using the required simple packing. 2. Recommendation: Users should be aware of the changing GRIB 2 packing for given model. |
