|The 15-minute precipitation data for this station are
temporary and will only be displayed for 120 days. Time series
of 1-hour or cumulative daily values will NOT be available for
retrieval following the 120-day display period. Although the
instrumentation is calibrated at least once a 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.
