This site is operated by the USGS AZ Water Science Center.
The 15-minute precipitation data for this station are temporary
and will only be displayed for 120 days. Time series of 15-minute or cumulative daily values will NOT be available for retrieval following the 120-day display period. Although the instrumentation is calibrated at least once per 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.
