Hanford Site Climatological Data Summary 2001 with Historical Data

Abstract

This document presents the climatological data measured at the U.S. Department of Energy's Hanford Site for calendar year 2001. Pacific Northwest National Laboratory 1 operates the Hanford Meteorology Station and the Hanford Meteorological Monitoring Network from which these data were collected. This report contains updated historical information for temperature, precipitation, normal and extreme values of temperature and precipitation, and other miscellaneous meteorological parameters. Further, the data are adjunct to and update Hoitink et al.

Multiphase Reactive Transport Modeling of Seasonal Infiltration Events and Stable Isotope Fractionation in Unsaturated Zone Pore Water and Vapor at the Hanford Site

“…However, to focus on the effects of infiltration in semiarid climates, and to simplify the interpretation of these results, the effects of temperature gradients and transient temperature profiles will be addressed in a future study. Isothermal models provide a reasonable approximation to field conditions at Hanford in the wet winter months, when measurements of soil temperature (Hoitink et al, 2002) show the least variation with depth.…”

“…Like many semiarid localities, local precipitation at Hanford exhibits strong seasonal fluctuations, from averages around 26 mm mo −1 during the winter months to 7 mm mo −1 during the dryer summer months (Gee et al, 1992; Hoitink et al, 2002). The precipitation variations are accompanied by seasonal shifts in average relative humidity and temperature, from approximately 70% at 1°C in the winter to 40% at 23°C in the summer (Hoitink et al, 2002).…”

Final Hazard Categorization for the Remediation of Six 300-FF-2 Operable Unit Solid Waste Burial Grounds

“…Temperature extremes vary from -29°C to 46°C (-20°F to 11 5°F) on the Hanford Site (Hoitink et al 2002). Climatological data are available from the Hanford Meteorological Station (HMS) (which is located between the 200 East and 200 West Areas on the Hanford Site) and from the 300 Area meteorological station.…”

Hanford Site Climatological Summary 2004 with Historical Data

“…From late 1943 until mid-1944, the U.S. Weather Bureau recorded (Jenne and Kerns 1959;Stone et al 1972Stone et al , 1983Hoitink and Burk 1994, 1996, 1997Hoitink et al 1999Hoitink et al , 2000Hoitink et al , 2001Hoitink et al , 2002Hoitink et al , 2003Hoitink et al , 2004). …”

The hottest temperature was 107°F on August 13, while the coldest was -14°F on January 5.…”
