Dear Rich
I rewrite at your question.
I use a mathematical model applicated to lagoon system.
I take the model output results I need , for example see level, substances,
spread by the tidal current, concentration..., and I stored them in a NetCdf
file..
I had build a program written in Fortran f90 that creates automatically the
NetCdf file using own Netcdf APi routine.
When I write the Netcdf File I use CF and COARDS convention.
I attach an exemple of the nc.file and the same in cdl format for a first
reading.
What i Need is a software that can read my netcdf file to display the data
stored in it, for a dinamic visualization!
Can you help me to understand the step I must take?
Matteo Previdi
I'm Interesting in knowing your projects about NetCdf develops...maybe to do
something alltogheter!
