NetCDF Framework is a Objective-C interface to the NCAR NetCDF library. Version 2.0 introduces several new classes. NCDFSeriesHandle, NCDFSeriesDimension, and NCDFSeriesVariable classes are designed to treat multiple netCDF files as a single entity, provided they are a time-sequential series of files. NCDFSlab is a new class that serves as an in-memory data store for netCDF data. The practical purpose of the slab is to "pre-fetch" data into memory and still allow data access using the standard dimensional notation. The compiled version is universal binary.
