precipitation data for this station are temporary and will
only be displayed for 120 days. Time series of cumulative daily
values will NOT be available for retrieval following the 120-day
display period. Although the instrumentation is calibrated at least
once/year, the temporary classification means that documented routine
inspections and other quality assurance measures are not performed
that would make the data acceptable for archival, retrieval, or
future use in general scientific or interpretive studies.
This station managed by the Rolla Field Office.
