Comparative Analyses on Two Kinds of Observed Evaporation Data in China

Through the comparison of the evaporation data between E-601 (large model) and 20 cm (small model) equipments since 1980 in China, the characteristics of the two kinds of data are analysed, and their conversion coefficient, correlation coefficient and deviation are given. A corrected formula of evaporation by which the large-model evaporation data are computed from small-model evaporation data is established
