CDFDatasets

CDFDatasets.jl is a julia package to read Common Data Format (CDF) datasets compatible with the CommonDataModel.jl interface.

It provides a high-level interface with features:

• Concatenation of multiple CDF files;
• Multi-backend support (CommonDataFormat.jl and CDFpp (C++));
• Integration with DimensionalData.jl.

It is recommended to use the native Julia implementation CommonDataFormat.jl for reading CDF files. CDFpp backend is mainly used for cross-validation, available in the PyCDFpp directory.

Quick Example

using CDFDatasets

# Open a CDF file
ds = CDFDataset("omni_coho1hr_merged_mag_plasma_20250901_v01.cdf")
times = ds["Epoch"]
bx = ds["BR"]
