摘要
为了便于将过去 40多年的小型蒸发器观测资料与E 6 0 1B蒸发器观测资料衔接使用 ,对全国 6 1 8个基准和基本站直径 2 0cm小型蒸发器与E 6 0 1B蒸发器 3年平行对比观测结果进行了统计 ,按省 (市 )给出了这两种仪器的月、年平均折算系数值及年折算系数的全国分布图 ,并给出了相应的标准差和相对标准差。
In order to connect evaporation data observed from 20 cm diameter evaporation pans in the past 40 years with those from E-601B pans, a comparison of evaporation data is made between 20 cm diameter pan and E-601B pan from 618 evaporation experimental stations for three years. The monthly and annual-mean conversion coefficients for the two instruments and the nationwide distribution chart of the annual-mean coefficient, as well as the corresponding standard deviation and relative standard deviation, are given.
