Detailed Description

Basic NetCDF-4/HDF5 format file creation and format detection (Fortran)

Fortran equivalent of simple_nc4.c, demonstrating NetCDF-4 format using the Fortran 90 NetCDF API. Creates a simple 2D array with NF90_NETCDF4 flag.

Learning Objectives:

• Understand NF90_NETCDF4 flag in Fortran
• Learn format detection with nf90_inq_format()
• Prepare for NetCDF-4 features (compression, chunking, groups)

Fortran NetCDF-4 Constants:

• NF90_NETCDF4 - Create NetCDF-4/HDF5 format file
• NF90_FORMAT_NETCDF4 - Format detection constant

Prerequisites:

• f_simple_2D.f90 - Basic Fortran NetCDF operations
• simple_nc4.c - C equivalent

Related Examples:

• simple_nc4.c - C equivalent
• f_compression.f90 - NetCDF-4 compression
• f_chunking_performance.f90 - NetCDF-4 chunking

Compilation:

gfortran -o f_simple_nc4 f_simple_nc4.f90 -lnetcdff -lnetcdf
