NOMADS Status at NOAA's Climate Diagnostics Center

- Storing all data in one file impractical because of the size
- Each variable (64 in total at two temporal resolutions) is a 54 year time series stored in 54 files each
- A GrADS Data Descriptor File (DDF) that synthesizes a time axis that spans the 54 year range is created for each variable and used by the GDS as a data object
- Some data "aggregated" in time via GDS and some via the Unidata Catalog/Aggregation server
- Experimental alternative to simpler internal "aggregation" available through Ferret
