## プロジェクトの歴史と使われ方

NCO, the netCDF Operators, is a suite of standalone shell commands for manipulating netCDF, HDF, and DAP scientific-data files. The project sits in the geoscience data-tooling world: derive fields, compute statistics, print and hyperslab data, edit metadata, concatenate files, regrid data, and emit text, binary, or netCDF outputs.

### プロジェクトの歴史

Charlie Zender's NCO documentation traces the package back to software needs from NCAR, NASA, and ARM-funded work, with copyright beginning in 1995 and a May 1997 foreword offering the tools freely to the scientific community. Unidata's netCDF history places NCO 1.0 in June 1997, one month after netCDF 3.3.

### 採用の歴史

NCO became a durable part of the netCDF ecosystem because it gives scientists scriptable Unix-style tools instead of requiring a custom C, Fortran, Python, MATLAB, or IDL program for every data-editing task. The project says SourceForge began hosting NCO in March 2000, which helped collaboration, contributions, and support.

### 使われ方

Package users reach for commands like ncks for inspection and extraction, ncrcat for record concatenation, ncra or ncwa for averages, ncatted and ncrename for metadata cleanup, ncap2 for derived variables, and ncremap/ncclimo for climate and regridding workflows. The shell-command style is the point: build reproducible data-processing pipelines with normal scripts.

### パッケージ好きにとっての重要性

NCO is a classic example of domain-specific CLI tooling that stayed relevant because the file format stayed relevant. It is important for package collections because it bridges lower-level libraries such as netCDF and HDF with practical batch workflows used by climate, atmospheric, oceanographic, and earth-system researchers.

### タイムライン

- 1995: NCO source/documentation copyright begins and the project describes itself as GPL open source since 1995.
- June 1997: Unidata history records Charlie Zender releasing NCO 1.0.
- March 2000: SourceForge hosting begins for collaboration and support.
- 2008: Recommended software citation published in Environmental Modelling & Software.
- 2020s: 5.x releases continue adding climate, remapping, compression, and model-workflow features.
