Climatic_Data(1961-1995)

The data are the five climatic variables with a time period of 1961-1995, including days of temperature ≥ 10℃, accumulated temperature≥10℃, average annual temperature of January (the coldest month), average annual temperature of July (the warmest month), and average annual extremely lowest temperature. The climatic variables with DEM were developed as environmental database for knowledge extraction.本数据集包含1961年至1995年时段内的5项气候变量，具体包括：日平均气温≥10℃的天数、≥10℃活动积温、1月（全年最冷月份）的平均气温、7月（全年最热月份）的平均气温，以及年极端最低气温平均值。将上述气候变量与数字高程模型（Digital Elevation Model，DEM）结合，构建得到可用于知识提取的环境数据库。
