GAGE HEIGHTS OF IMPORTANCE
|The 15-minute precipitation and air temperature 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.
