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!
