netcdf3

Description

A pure Rust library for reading and writing NetCDF-3 files.

Technical features

• Read a NetCDF-3 file :
  • Read a variable data.
  • Read a subset of a variable data.
  • Read a variable data into a N-dimensional array (using the crate ndarray).
• Write a NetCDF-3 file :
  • Write a variable data.
  • Write a subset of a variable data.
  • Write a variable data from a N-dimensional array (using the crate ndarray).

Notes

• If the number of records numrecs is greater than std::i32::MAX then this value is considered as indeterminated (numrecs = 2^32 - 1) (see the File Format Specifications).
• If the chunk size of a given variable vsize is greater the std::i32::MAX then its value is considered as indeterminated (vsize = 2^32 - 1) (see the File Format Specifications).
• For the file writing, binary comparisons between the crate outcomes and files produced by the Python library (netCDF4) are done while the test suite (see the Python script pyscripts/create_test_nc3_files.py and the Rust test file tests/tests_write_nc3_files.rs.)

Known limitations

• Cannot read/write too large NetCDF-3 files. Cannot read/write a subset of a variable data yet.
• Cannot rewrite the NetCDF-3 files (append/remove records, edit dimensions/attributes/variables, ...).
