[ROOT]/[yyyymmdd]/[HH]z/[model]/0p25/[stream]/[yyyymmdd][HH]0000-[step]h-[stream]-[type].grib2 [ROOT] is the top-level URL of one of the sites hosting the data. See the above for possible values.
[yyyymmdd] is the reference date of the forecasts (base date).
[HH] is the reference time of the forecasts. Values are 00, 06 , 12 and 18.
[model] is the production model (IFS or AIFS). Note: IFS and AIFS have different options, so please be review dataset pages to see what is available.
[resol] is the horizontal resolution of the data. Options include: 0p25 or 0p4-beta
[stream] is the forecasting system that produces the data. Values are:

• oper - high-resolution forecast, atmospheric fields
• enfo - ensemble forecast, atmospheric fields (not applicable for AIFS model)
• waef - ensemble forecast, ocean wave fields, (not applicable for AIFS model)
• wave - wave model, (not applicable for AIFS model)
• scda - short cut-off high-resolution forecast, atmospheric fields (also known as "high-frequency products") (not applicable for AIFS model)
• scwv - short cut-off high-resolution forecast, ocean wave fields (also known as "high-frequency products") (not applicable for AIFS model) and
• mmsf - multi-model seasonal forecasts fields from the ECMWF model only (not applicable for AIFS model).
  高精度予報、00h, 12h は、oper、06h, 18h は、追加情報で scda。

[step] is the forecast time step expressed in units U
　　高精度予報、00h, 12h は、step=0h to 144h by 3h, 144h to 240h by 6h
　　　　　　　　06h, 18h は、step=0h to 90h by 3h
[type] is once of fc (forecast), ef (ensemble forecast), ep (ensemble probabilities) or tf (trajectory forecast for tropical cyclone tracks).
[format] is grib2 for all fields, and bufr for the trajectories.
