Publicly available data

NIWA makes available and regularly updates results from several greenhouse gas measurement projects in two forms.

  • Tabular data: Data that have been carefully checked are available in tabular form via our anonymous FTP site as selected trace gas and associated data sets. This generally includes data used in our scientific publications as well as some unpublished data. Users of this data should be familiar with the underlying scientific literature and begin by reading the “README.doc” file in the "tropac" directory. Use of our data should always cite its origin as described in the “readme.txt” or “readme.doc” files closest to the corresponding data files in the directory tree underneath “tropac”.
  • Graphical summaries: records above are also available as graphical summaries. Some of these summary graphs include preliminary data that is not yet released in tabular form.
