Meteorologists use a wide array of instruments to measure weather conditions. At the University of California, Davis, students studying atmospheric science get an up-close look at those various instruments 鈥 some of which were first designed in the late 1800s 鈥 to gather data to predict the weather.
Alexis Clouser and Brody Adams, both seniors majoring in atmospheric science, have woken up with the sun many times to record weather conditions at the 新澳门六合彩内幕信息 Davis Weather Climate Station, located west of the main campus near Campbell Road. They are among a rotating group of students who are responsible for visiting the station each day by 8 a.m. to collect and record the data.
鈥淚t feels like you鈥檙e doing something important, and that you are part of something that鈥檚 been going on since the 1870s.鈥 鈥 Brody Adams
The station features historical instruments that continuously monitor atmospheric variables, including daily high and low temperatures, wind speed and direction, and precipitation. The station has a westward-facing observation deck that, on some days, allows for a great view toward the city of Winters.
鈥淥n a really clear day, you can see what seems like practically every oak tree on the mountains,鈥 Clouser said.
Atmospheric science professor Kyaw Tha Paw U said that according to the National Centers for Environmental Information, the 新澳门六合彩内幕信息 Davis station, which was previously called the Davisville Experimental Farm Station, has been in operation since 1871. Although there are some gaps in the data between the late 1800s and the early 1900s, there are original Davis weather station that date back to March 1906 (they can be accessed on a National Oceanic and Atmospheric Administration ). The 新澳门六合彩内幕信息 Davis station is part of the U.S. Historical Climatology Network, and when observations are made on campus, the information is saved in a database. The data is also shared with the National Weather Service, and students present the weather on the atmospheric science department鈥檚 each morning.
Instruments old and new
Clouser and Adams are highly skilled at manually recording the readings from the decades-old instruments at the station. During each visit, they check out the two liquid-in-glass thermometers, stored in a wooden enclosure, to record the high and low temperatures.
鈥淚n the winter, I like to see what the low was, that鈥檚 cool to see,鈥 Adams said. 鈥淚n the summer, it鈥檚 kind of dreadful seeing how hot it got.鈥
鈥淲hen we had that heat wave last July, it was around 113-114 degrees,鈥 Clouser said.
They also look at anemometers, which measure the direction and speed of wind. There are two rain gauges; one electronically measures any rainfall, while the other is done manually. One of the oldest instruments at the station is called a Campbell Stokes Recorder, which was first invented in 1853. It鈥檚 a glass sphere that is used to measure the duration of bright sunshine.
These daily weather observations not only help create near-future forecasts, but they are also important for generating future climate outlooks that are critical for farmers and water managers.
Future weather plans
After they graduate from 新澳门六合彩内幕信息 Davis, both Clouser and Adams hope to land a job at one of the six National Weather Service offices in California. They both believe that their knowledge of predicting the weather using weather instruments, like those at the campus station, will help them in the future.
鈥淚t helps solidify your basic understanding of the operational meteorological instruments collecting your data,鈥 Clouser said. 鈥淚f you鈥檙e sitting in a NWS forecast office, these are the instruments that are sending you all that data, so it鈥檚 nice to see what exactly you鈥檙e working with.鈥
It also gives them a chance to be a part of campus weather and climate history.
鈥淚t feels like you鈥檙e doing something important, and that you are part of something that鈥檚 been going on since the 1870s,鈥 Adams said. 鈥淚t鈥檚 really cool.鈥
