The weather at the Lab Homes provides context for the data gathered from the experiments that take place in the homes. Temperature, humidity, wind speed, and precipitation all have an impact on the results of the experiment, and must be recorded and understood if the data from the experiments is to make sense.
Richland, Washington, where the Lab Homes are located, is in the southeastern part of the state, at the confluence of the Yakima and the Columbia Rivers. Richland, along with the nearby cities of Kennewick and Pasco (and surrounding communities of West Richland, Finley, Burbank, and Benton City), make up what is known as the Tri-Cities region, which is a semi-arid region averaging 7 to 8 inches of precipitation each year. Temperatures in this region typically range from wintertime lows in the mid 20s °F to summertime highs in the low 100s °F.
