H.J. Andrews Experimental Forest is a 6400 ha forest of Douglas fir, western hemlock, and Pacific silver fir located in, and typical of, the central portion of the western slope of the Cascade mountain range of Oregon. The forest is one of 19 sites in the Long-Term Ecological Research (LTER) program sponsored by the National Science Foundation (Franklinet at 1990). During the 1970s it was a representative site in the Coniferous Forest Biome Project of the U.S. International Biological Program. It was originally established in 1948 as an Experimental Forest of the U.S. Forest Service. An immense legacy of research has resulted from the participation of Andrews Forest in these programs (McKee et al 1987,Blinn et al 1988). Future participation in LTER ensures the continuing scientific importance of the site.
Climatological information has been collected at Andrews Forest since 1951, with a continuous, electronically-sensed record since May 1972. The observing system is composed of a primary meteorological station and a network of satellite temperature and precipitation recording stations. Because of the scientific significance of Andrews Forest, it is important to investigate the temporal variability of annual and seasonal temperature and precipitation values at the site and identify past times of anomalous climatic conditions. It is also important to establish quantitatively the relationships between the climate of Andrews Forest and that of its surrounding area and, hence, place the climate of Andrews Forest into its regional context.
