Data acquisition method: Acquisition method is pull from the provider's location to ECMWF's premises if not specified
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?
