Iliamna Station History

Located on Iliamna Lake near base of Alaska Peninsula. Current coordinates 59 degrees 45' N, 154 degrees 55' W, elevation 186'. Data 1920-1923 incomplete and site uncertain. Reopened for a few months in 1939, and again 4/1/41 through 5/31/42. Reopened as CAA station 8/1/42, moved 3 miles W and 77' uphill at that time, temperature recorded at 5'. Temperature instrument moved slightly 7/10/56. Observer USWB 4/28/67 - 5/20/70, then back to FAA. Slight move NNE and 41' up 11/7/74.

Observation time 5 pm in twenties, 9 am 1939, 3 pm old site 1941-42. New site started with observation time midnight. Observation time changed to 8 pm 11/7/74. Time changed to 9 am 11/24/87.

Observer primarily and presently FAA/CAA.

Record length short with very spotty data before forties; record continuity fair from 1943 except for major gap in early seventies; site continuity may have been broken 1974. Difficult to evaluate as other Alaskan stations show what may be a real climate break around this time. Temperature difference from King Salmon appears fairly constant across the gap, and the two stations track fairly well on annual mean since mid fifties.
