Attribute Accuracy:

Attribute Accuracy Report:
The accuracy of attributes for this theme are dependent on source materials; data were not modified by the ICBEMP beyond re-projection of datasets. Attribute accuracy information for source materials were not collected since acquisition of source data pre-dated FGDC metadata standards.
Logical Consistency Report: Not applicable to raster data.
Completeness Report: Weather files created by Peter Thornton at the University of Montana. Three years of annual attributes have been combined in this grid: 1982 (wet), 1988 (dry), 1989 (normal).
