About SILO and NC

SILO

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

NC

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

FAQs

Is converting SILO to NC free?

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

How long does it take to convert SILO to NC?

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

What is NC best used for?

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

Does converting SILO to NC lose quality?

No, converting SILO to NC does not cause additional quality loss — NC uses lossless compression. However, any artifacts already present in the original SILO file will persist in the NC output.

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

NC files are typically 2-5x larger than equivalent SILO files because NC preserves all pixel data. This is expected and necessary for lossless quality.

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.

What is NC?

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

When Should You Use SILO vs NC?

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.

Use NC When...

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

SILO vs NC: Key Differences

  • •SILO uses lossy compression while NC uses lossless compression — this is the fundamental technical difference between the two formats.
  • •The switch from lossy compression to lossless compression means you preserve full quality at the expense of larger file sizes.
  • •Alpha channel support: NC lacks transparency support.
  • •SILO files are typically 100MB to tens of GB per simulation step while NC files range MB to GB for model output
  • •SILO is optimized for petascale simulation data, hydrodynamics, hpc visualization while NC is designed for climate, oceanographic, and atmospheric model output — choose based on your specific workflow needs

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.

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.

Common Use Cases for SILO to NC Conversion

Industry Applications

Best Practices for SILO to NC Conversion

  • →When converting SILO to NC: verify that variable names, units, and dimensions are preserved
  • →Preserve metadata and provenance attributes so NC 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 SILO to NC Conversion

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