Read in Recommended support checks about hopefully helpful practises used at ECMWF which can be shared. Some examples and source codes are also available there.
Support checks (on provider's end)

- Data acquisition method: If not specified the data retrieval method is pull by ECMWF's acquisition system ECPDS from the provider's location
- Data transfer check: Is the data transfer checked to avoid any technical issues on the way from provider's location to ECMWF's premises? Was the data delivered bit identical?
- Data delay check: Is the potential delay of data availability checked on the provider's side?
- Data completeness check: Is the data content (number of expected fields; reference field list etc) checked on the provider's side?
- Data quality check: Is there any data quality control to avoid e.g. unrealistic parameter values due to interpolation or any other kind of error either scientific or technical?
- Not simple packing? The data should be packed using GRIB simple packing for faster processing by users (HW packing is used to archive the data)
- Data recovery option: Is it possible to recover any missing/corrupted data when needed?
- If yes, is there any time limit when the data can be rescued? If yes, specify number of days within which the recovery action must happen.
