Wrangell Station History

Located on coastal mainland SE Alaska, numerous mountainous islands between Wrangell and open ocean. Current coordinates 56 degrees 29' N, 132 degrees 22' W, elevation 44 feet. Short isolated records 1868-1870, 1875-1877, 1881-1882, 1904, 1908-1909. More or less continuous starting 1917 with thermometer in non-standard shelter at 5 feet. Move 0.1 mile SW and 40 feet downhill 9/1/19; thermometer height unknown. Move 0.2 miles NNE and 25 feet uphill 11/1/22; thermometer height 3 feet. Move 0.5 miles NW and uphill 15 feet 9/25/24, thermometer height 5 feet. Move 0.4 miles ESE 6/1/25, thermometer height lowered to 4 feet. Move 1.9 miles SE 1/16/27. Move 2.0 miles NNW and 32 feet downhill 11/30/30. Move unknown distance and direction and 23 feet uphill 2/15/41. Move 0.2 miles SW and 4 feet downhill 8/10/41. Move 1.0 miles NNE and 7 feet uphill 11/15/84, maxMin system added.

Time zone changed from 120 WMT (PST) to 135 WMT (AST) at the end of October 1983. As the 135 WMT is closer to mean solar time, the earlier observation times are given both as recorded and as 135 WMT (in parentheses.) Observation time first recorded as 5 pm (4 pm corrected) in 1904, 6 pm (5 pm corrected) 1908-09. Time 5 pm (4 pm corrected) 11/1/17, 4 pm (3 pm corrected) 9/1/19, 5 pm (4 pm corrected) 9/25/24, 9 am (8 am corrected) 1/6/27, 6 pm (5 pm corrected) 11/30/30, 5 pm (4 pm corrected) 8/10/41, 4 pm (3 pm corrected) 12/1/63. Change of time zone end of October 1983 shifted observation time back to 4 pm.

Observer cooperative, currently Wrangell Air Service.

Record length excellent, data continuity fair at best, site continuity poor. Aside from roughly 4 years in late 20's, all observations afternoons.

Comparison with nearest stations Annette and Ketchikan suggests major differences over 60's and 70's compared to rest of record (Wrangell low)
