Questions & Answers
CDF files: Frequently Asked Questions
What are CDF files?
CDF (Network Common Data Format) is a portable, self-describing binary container for multidimensional scientific arrays, maintained by Unidata. A classic file starts with the signature "CDF" followed by a version byte (1 for classic, 2 for 64-bit offset, 5 for 64-bit data), then a header listing dimensions, global attributes, and variable definitions, and finally the data in big-endian order, with fixed-size variables preceding record variables along the unlimited dimension. Newer NetCDF-4 files use an HDF5-based container with chunking and compression. Variable types include byte, char, short, int, float, and double, while conventions such as CF define coordinate variables, units, and the scale_factor, add_offset, and _FillValue attributes. Conversion to graphics begins with selecting a variable and fixing its time and level indices to obtain a two-dimensional slice, then unpacking the values, masking fill values, and correcting axis order, since latitude may run south to north and longitude may span 0 to 360 degrees. The slice is rendered as a grayscale or color-ramped image in PNG, JPEG, or TIFF, or saved as GeoTIFF with the coordinate system taken from the grid mapping variable. Supported by Panoply, ArcGIS, QGIS, Global Mapper, ENVI, and MATLAB.
