Click to hidestation-specific text
The 15-minute Wind Speed, Wind Direction, Air Temperature, Relative Humidity, and Barometric Pressure data for this station are temporary and will only be displayed for 120 days. Time series of 15-minute daily values will NOT be available for retrieval following the 120-day display period. The temporary classification means that documented routine inspections and other quality assurance measures are not performed to the level required to make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
