Web Coverage Service Access from NetCDF Files.

The goal is to provide you an easy way to publish your data in NetCDF format.

The cross-platform toolkit from data to Web Service contains:

  • Checking the CF-1.0 compatibility of your data.
  • Creating CF-1.0 compatible NetCDF files from your data.
  • Setting up a Web Coverage Service directly from your files with no extra configuration.

Below are sections and descriptions to all the tools we provide. Feel free to participate!

Cross Platform Python-NetCDF Library

The most feature-rich library to access NetCDF files via python is PyNIO. Unfortunately it is unix-only. That's why nc3 was created. The two purposes of nc3 are:

  • Provide simple read and write access to NetCDF files.
  • WCS query: Extract a subcube from a NetCDF.

This is supposed to be a small library. The subcube query is supposed to be fast, everything else is supposed to be simple. If you do a lot of data processing using NetCDF or python, we recommend PyNIO.

NetCDF Markup Language: NCML

Creating a NetCDF file via plain API is difficult, NCML allows you to describe dimensions, variables and attributes in one xml document. This simplifies creating an empty NetCDF file a great deal.

Example NCML use:

CF-1.0 Convention

It's not enough to have NetCDF as format, you also need to standardize the attribute names, how to store dimensions etc. To make it easy to create CF-1.x compatible files, we provide a python library cf1.
