Luke Howard is best known for the naming system of clouds and dabbled in urban temperatures and those in the country.  As noted in Tuesday's Weather News, Noah Webster may be known for the dictionary but also displayed his expertise in climatology.  An analysis of his writings, reported in Weatherwise Magazine, indicates that Noah may have beaten Howard by 21 years as Webster published in 1799 on the effects of weather.  His observations, made in New York for one year, found the mean temperature to be 1.5 degrees higher; predicting that excess city heat was the cause.  He explained, "The air in the city cools less at night, than the country and ice as thick as glass formed a mile from New York."
