Data access

Gridded model outputs

  1. Data portal
    The simplest way how to get rather smaller ad hoc data samples (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).

    In order to retrieve data efficiently users should follow the instructions about S2S reforecasts retrieval efficiency. Find here examples of efficient retrieval scripts for different S2S datasets via ECMWF Web API


  3. CMA data portal
    The 2nd official S2S data portal where all data from all partners can be downloaded.
  4. IRI library
