The 15-minute precipitation data for this
station are temporary and will only be displayed for 120 days.
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.
