Personal Weather Station Owner Corrects National Weather Service During Dinner Party

A dinner party was briefly derailed Saturday evening when the host corrected the National Weather Service's official temperature reading using data from his personal backyard weather station, a discrepancy of 0.3 degrees Fahrenheit that he characterized as "not trivial." Host Gerald Anemometer, 56, interrupted a conversation about vacation plans to announce that the NWS had reported the current temperature as 72.1 degrees Fahrenheit when, according to his Davis Vantage Pro 2 weather station installed on a ten-foot mast in his backyard, the actual temperature was 72.4 degrees. "Three-tenths of a degree," Anemometer stated, showing the Weather Underground page on his phone where his station's data is publicly uploaded. "They're reporting from the airport, which is eight miles away and surrounded by tarmac. My station is at ground truth. I'm measuring the actual microclimate of this neighborhood." Guests nodded politely and attempted to resume the vacation conversation. Anemometer continued. "The humidity is also off. They say 54%. I'm reading 57%. That's a dew point discrepancy of at least a degree. If you're a farmer, that matters. If you're trying to decide whether to water your lawn, that matters." "Nobody at the table is a farmer," observed his wife, Carol, who had heard the weather station speech at previous dinner parties. "And you don't water the lawn. You pay a service." Anemometer has invested approximately $1,200 in his weather station setup, which includes temperature, humidity, wind speed, wind direction, barometric pressure, UV index, and rainfall sensors. The data is uploaded to Weather Underground every ten seconds, where his station ranks among the top twenty in the metropolitan area by data quality score. "I have seventeen followers on Weather Underground," Anemometer noted. "People rely on my data. The NWS is good for the general area. I'm good for this street." The dinner party resumed after twelve minutes. The vacation plans remain undiscussed.
