Mike Barnum, Tim Stieber, and Clint Shock Malheur Experiment Station Oregon State University Ontario, Oregon, 1990 Daily observations of air temperature and precipitation have been recorded at the Malheur Experiment Station since July 20, 1942. Installation of additional equipment in 1948 allowed for evaporation and wind measurements. A recording soil thermometer was added in 1967 and instruments to monitor growing degree days and solar radiation in 1985. In 1962 the station began cooperating with the U.S. Department of Commerce, Environmental Science Service Administration, National Weather Service. Each day the 8:00 A.M. air temperature, preceding twenty four hour air and soil temperature extremes and twenty four hour accumulated precipitation are recorded and transmitted to radio station KSRV in Ontario. KSRV then conveys this information, along with their daily readings, to the U.S. Weather station in Boise, Idaho. During the irrigation season (April - October) evaporation, wind and water temperature are also monitored and reported. Total precipitation of 7.21 inches (Table 1) represented the lowest amount since 1966 when only 5.74 inches was recorded. This made 1990 the seventh consecutive year with below average precipitation (Table 2). The fall (October-December) 1989 and winter (January-March) 1990 seasonal moisture total of 2.62 inches was the lowest amount in the past 10 years (Table 3). This lack of precipitation set new records in that it represented the first time no monthly total within the period exceeded one inch (Figure 1) and it was the lowest amount ever recorded during that six-month interval at this station. With near record temperatures recorded during August and evaporation exceeding the ten year average during April, May, July, and September the seasonal total evaporation was 1.50 inches above average (Table 4). The total miles of wind was the lowest recorded during the period since 1977. A last spring frost, May 8, and first fall frost, October 9, resulted in a 153 day frost free period which equaled the thirty year, (1961 to 1990), average (Table 5). Air temperature ranged from a high of 106°F on August 8 to a low of -21°F on December 24. An absence of snow cover coupled with the December 19 arrival of a severe cold front caused the four- inch soil temperature to drop to a record breaking 12°F from December 24 through 26 (Table 6). These conditions effectively reduced the mean air and four-inch soil temperatures well below the monthly averages (Table 7 and Figures 2 and 3). 1 Total cumulative growing degree days as of the end of September were relatively near the five year average (Table 8 and Figure 4).
