(907) 474-7114 Associated investigator 2007-03-01 Part of the Long Term Tree Growth study. This dataset is an accumulation of various manual measurements made on a weekly to monthly basis. It originally included snow stakes, rain buckets, max/min thermometers and a series of soil temperature sensors. Over the years equipment has changed. The soil temperature sensors exceeded their field life during the 1990's and were dropped from the study. In 2001 logging air temperature and relative humidity sensors were installed and those measurements were discontinued. In 2002 logging rain gauges were installed to replace the manual buckets. Both styles were during that growing season and the manual buckets were removed before the 2003 field season. All that remains active in this dataset are the snow stake measurements. air temperature precipitation soil temperature snow depth Climate

.04 ha plots for environmental monitoring.

Air Temperature maximums and minimums collected with standard USWB thermometers (1968-2001;discontinued). Rain measurments collected with standatd bucket style rain gauges (1968-2002; discontinued). Snow depth read from fixed snow stakes with mesurment marks (1968-present). Soil tempertures read with handheld digital temperature sensor reader and switched individual sensors (1968-2000; discontinued).
