FAQ
NC4 to PGM Conversion
What are NC4 files?
NC4 is a file extension used for NetCDF-4, the fourth generation of the Network Common Data Form, a format for storing scientific data that is maintained by Unidata at the University Corporation for Atmospheric Research. It is widely used for weather, climate, ocean, and satellite data, where measurements are organized as multidimensional arrays, for example temperature at a grid of locations over time. A file describes itself: it holds the data together with names, units, and notes on what they mean. NetCDF-4 appeared in 2008 and uses the HDF5 format underneath, which allows data to be compressed and grouped in folders inside the file. Although the official recommendation is to use the .nc extension for all versions, some data providers choose .nc4 to mark the newer format.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
