We've moved to Gitlab! (gitlab.com/remikz/nccmp)
Compares two NetCDF files in-place to find specific variables, dimensions and/or attributes that differ. Highly recommended for any test-driven environment and regression testing large datasets.

Features

  • Multi-threaded if posix threads supported.
  • Groups (netcdf4) recursively, by short or full name.
  • Header pad comparisons.
  • Limit diffs up to global total or per-variable counts.
  • Support all Netcdf4 atomic and user-types, with nesting.
  • Can treat NaN's as equal if used as grid masks.
  • Written in pure C and builds on many platforms.
  • Allow asymmetric data types when comparing semantically.

Project Samples

Compare metadata for non-record variables. Compare data using a tolerance threshold. Statistics and color features.
