About NC and SILO

NC

NC (NC) - Network Common Data Form - self-describing array-oriented scientific data. Best for climate, oceanographic, and atmospheric model output.

SILO

SILO (SILO) - Silo - LLNL mesh and field data format for large-scale scientific simulations. Ideal for petascale simulation data, hydrodynamics, hpc visualization.

FAQs

Is converting NC to SILO free?

Yes, GoConvertFile offers free conversion of NC to SILO for files up to 100MB. No registration required.

How long does it take to convert NC to SILO?

Most NC to SILO conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is SILO best used for?

SILO is ideal for petascale simulation data, hydrodynamics, hpc visualization. Silo - LLNL mesh and field data format for large-scale scientific simulations

Does converting NC to SILO lose quality?

Yes, converting NC to SILO uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.

What file size should I expect after converting NC to SILO?

SILO files are typically 50-80% smaller than NC files because SILO uses efficient lossy compression. The exact reduction depends on quality settings.

What is NC?

NetCDF (Network Common Data Form) is a self-describing, array-oriented format widely used for climate, oceanographic, and atmospheric science data.

What is SILO?

SILO is a portable file format developed at Lawrence Livermore National Laboratory for storing multi-dimensional mesh and field data, supporting structured grids, unstructured meshes, and point data for large-scale scientific simulations.

When Should You Use NC vs SILO?

Use NC When...

Reach for NC when your priority is climate, oceanographic, and atmospheric model output — its uncompromising quality ensures every detail is preserved.

Use SILO When...

Reach for SILO when your priority is petascale simulation data, hydrodynamics, hpc visualization — its efficient compression makes sharing fast and storage minimal.

NC vs SILO: Key Differences

  • •NC and SILO diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Converting from NC to SILO changes compression type: lossy source becomes smaller but with some quality tradeoff.
  • •Transparency: N/A - binary HDF5-based format — converting from NC will merge transparency into a solid background
  • •Storage footprint: MB to GB for model output for NC vs 100MB to tens of GB per simulation step for SILO.
  • •NC is optimized for climate, oceanographic, and atmospheric model output while SILO is designed for petascale simulation data, hydrodynamics, hpc visualization — choose based on your specific workflow needs

Advantages of NC

  • ✓NC applies lossless compression specifically calibrated for Climate, oceanographic, and atmospheric model output.
  • ✓NC enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓NC guarantees every bit of the original data survives — no approximations, no shortcuts.
  • ✓You will find NC support built into virtually every tool that handles Climate, oceanographic, and atmospheric model output — no plugins or converters needed.

Advantages of SILO

  • ✓SILO applies lossy compression specifically calibrated for Petascale simulation data, hydrodynamics, HPC visualization.
  • ✓SILO enjoys broad native support across operating systems, browsers, and creative tools alike.
  • ✓SILO delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
  • ✓You will find SILO support built into virtually every tool that handles Petascale simulation data, hydrodynamics, HPC visualization — no plugins or converters needed.

Common Use Cases for NC to SILO Conversion

Industry Applications

Best Practices for NC to SILO Conversion

  • →When converting NC to SILO: verify that variable names, units, and dimensions are preserved
  • →Preserve metadata and provenance attributes so SILO remains scientifically interpretable
  • →Check that multi-dimensional arrays (time, depth, lat, lon) map without truncation
  • →Confirm endianness and numeric precision are handled correctly for the target format output
  • →Always keep a backup of your original files before converting
  • →Choose the appropriate quality settings for your specific use case

Troubleshooting NC to SILO Conversion

  • !Coordinate variable ordering is wrong in the converted SILO → CF conventions expect (time, depth, lat, lon) ordering
  • !Missing values / fill values are not recognized by tools reading SILO → check that the fill value attribute transferred correctly
  • !The converted SILO file has incorrect data type → data precision (float32 vs float64) should match the original's requirements
  • !Dimension scales are off in the converted SILO → verify that scale_factor and add_offset were preserved during conversion
