using netCDF for storing data from realtime source

[Larry D. Oolman]

A netCDF convention to do a similar action has been developed for atmospheric research
aircraft.  You can read about it at
   http://www.eol.ucar.edu/raf/Software/netCDF.html

Each measurement or calculation is stored as a 2D variable.  The first
dimension is time at once per second.  It can be unlimited for a realtime
growing file.  The second dimension is samples
per second.  There is also a third dimension for vector data, but it
sounds as if you don't need that.  The use of two dimensions allows
data for different rates to be stored.  The beta tested netcdf-4 will
allow more than one unlimited dimension.
