His first job in astronomy as at the United States Naval Observatory until he was offered the director position at the Cincinnati Observatory, in 1868, by the Cincinnati Astronomical Society. He spent a few years in Cincinnati, but his interests were already evolving. Remembering that meteorological conditions directly affected the work of astronomers, he began working in the field of meteorology. He won approval to report on and predict the weather, working on the premise that forecasts could and should be generated at minimal expense and in such a way as to perhaps even produce income. By 1873 he was let go by the Cincinnati Observatory due to funding issues and it was then that he made the decision that would change his career path. His first work on weather was centered on forecasting and issuance of warnings for severe weather. This preliminary work was started while still in Cincinnati. His first bulletin was issued on 1 September 1869. Abbe was appointed chief meteorologist at the United States Weather Bureau on 3 January 1871, which at the time was part of the Signal Corps. One of the first things that he addressed was the forecasting dimension of meteorology. He recognized that predicting the weather required a widespread, yet coordinated team. And so with short-term funding granted from the Cincinnati Chamber of Commerce, he enlisted twenty volunteer weather observers to help report conditions. Western Union agreed to permit the observers to communicate without charge, and Abbe and his team went to work. He selected data-collecting instruments that would be critical to the success of weather predicting, and he trained Army observer sergeants in their use. Field data was transmitted using code designed to minimize word count, and at the designated times, information flooded the transmission stations. Clerks would then decode and record the messages and manually enter data onto weather maps, which were then used to predict the weather. On February 19, 1871, Abbe personally gave the first official weather report. He continued to forecast alone for the next six months, while simultaneously training others. He was joined in mid-1871 by two Army lieutenants and a civilian professor in giving reports, and the team was then able to rotate the heavy workload. Abbe demanded precise language in the forecasts and ensured that every forecast covered four key meteorological elements: weather (clouds and precipitation), temperature, wind direction, and barometric pressure. By the end of the first year of reporting, over 60 copies of weather charts had been sent to Congress, the press, and various scientific institutions. By 1872, Abbe regularly sent over 500 sets of daily maps and bulletins overseas in exchange for European meteorological data.
