Datasets are managed by a variety of people and projects within CRU. Some are available on-line, others must be requested from the person responsible for them.
Files ending in ".gz" can be decompressed using gzip (most platforms) or WinZip (Windows 9x/NT).
The various datasets on the CRU website are provided for all to use, provided the sources are acknowledged. Acknowledgement should preferably be by citing one or more of the papers referenced on the appropriate page. The website can also be acknowledged if deemed necessary. CRU will endeavour to update the majority of the data pages at timely intervals although this cannot be guaranteed by specific dates.
