Abstract: Meteorological observation data is the basis of weather forecast early warning, climate prediction and scientific research, which is the original force to promote the development of meteorological science. Hailun Agricultural Ecology Experimental Station, Chinese academy of Sciences, which belonged to China ecosystem research network (CERN) and national long–term positioning research station, represented the farmland ecosystem in the black soil area of the Northeast China. The black soil area in which the Hailun Station located is one of the four black soil areas in the world. However, public report of the meteorological data of Hailun Station was still limited to individual meteorological elements until now, the whole meteorological elements of Hailun Station according to the time series had not been published. The original data was collected by VAISALA automatic observation system of the Hailun Station meteorological observation field. After data processing, quality control and evaluation, 17 tables, 116 KB of 10 year meteorological data from 2009 to 2018 was published. Our aims were to provide basic support for the development of national economy, especially local agricultural production activities.
