Revision Summary:

An alert data user called to our attention that in the Ecosystem Model-Data Intercomparison (EMDI) Class B data files for the Australian estimates of NPP and driver data, there were three errors in the locations of the original study sites. The reported site latitude and longitude were incorrect in the data files when compared with the description in the original literature publication.

Data File Changes:

Because the Site ID, latitude, and longitude are included in each data file, all Class B data files were updated and have a creation date of 2004/06/17.

No changes to data set documentation were necessary.

The referenced document was unaffected.
