Relational database (e.g. PostgreSQL)
pros:
- flexible
- conditional verification
- SQL queries
- easy to implement
cons:
- possibly very slow and hard to maintain as an estimated annual increases is around 100 TB
- probably a need for a tool preparing some common output data file for users from the database values
ODB
pros:
- full support at ECMWF
- can be stored in ECMWF MARS and use all its capability
- SQL like queries
- compression
cons:
- generally not too known format?
- not too flexible if any re-computations are needed
NetCDF
pros:
- well known format
- compression
cons:
- not ECMWF MARS support
- not too flexible if any re-computations are needed
