Data access

1. Data portal
   The simplest way is via ECMWF's data portal linked. It can be used only for small ad hoc data samples retrieval (approximately up-to 20 000 retrieved fields per request)  
2. Batch access
   The ECMWF access in batch should be used for most common types of work (big data samples retrievals)

Data  monitoring

1. Visual data quality monitoring
   For the purpose of simple visual data quality monitoring some maps and histograms are produced for every forecast date and chosen model outputs (see the link in the Resources section). Only the first perturbed eps member and control forecast (if exists) are monitored at two chosen forecast leading times (0 and the latest available one common for all monitored datasets)
2. History page
   The data gaps caused by any kind of problems can be checked via so called TIGGE-LAM history web page linked in the Resources section.
