How is UERRA data organised in MARS?
In general it is organised, as a huge tree, with the indentation below, showing different levels down that tree:
- origin and model (eg SHMI, Atmospheric model etc)
- type of data (analysis, forecast, etc)
- year
- month
- type of level (model level, pressure level, surface etc)
- dates, times, steps (for forecast type), levels (for non surface levels), parameters, members (for ensembles)
- dates, times, steps (for forecast type), levels (for non surface levels), parameters, members (for ensembles)
- type of level (model level, pressure level, surface etc)
- month
- year
- type of data (analysis, forecast, etc)
What would be the natural way to group requests?
The idea is to request as much data as possible from the same tape file . The natural way to group requests would be:
all parameters, all levels, all time-steps for all dates of a month
Note: 'all' means 'all' that the user wants. It doesn't have to be all parameters.
