Abstract
On the basis of eight atmospheric reanalyses we analyzed the spatialtemporal characteristics of global evaporation and also briefly evaluated the eight reanalyses The results indicate that the longterm mean annual evaporation obtained from different reanalyses are consistent over most regions with significant maritimecontinental contrasts as well as differences in meridional directions and the land evaporation generally decreases with the increase of altitude In addition the temporal evolution of global evaporation varies significantly among the datasets MERRA ERAInterim NCEPNCRA and NCEPDOE are very similar whereas CFSR agrees best with ERA40 Comparison of the interannual to interdecadal variability of land evaporation reveals large differences among the reanalyses whereas MERRA CFSR and NCEPDOE are exactly similar The temporal variation of evaporation over the oceans showed a relatively high consistency which indicates that the quality of the reconstructed evaporation values over the oceans is higher and even greater uncertainties lie in the estimates of evaporation over the land In general MERRA and NCEPDOE may appropriately reflect the spatialtemporal characteristics of global evaporation showing strong representativeness The CFSR and ERA40 are capable of revealing the characteristics of land evaporation whereas ERAInterim NCEPNCAR OAFlux and HOAPS are relatively applicable for research focused on the evaporation over the oceans According to ERA40 NCEPNCAR and OAFlux global evaporation significantly decreased for the period of 1958–1978 In contrast most of the eight reanalyses show a significant linear increase for the period of 1979–2011 and evaporation over the oceans was even more pronounced Furthermore the results are presented for the mean annual cycle of global evaporation the changes at the low latitudes in the Northern Hemisphere are most distinct and the monthly variation amplitude of the land evaporation was higher than that of the evaporation over the oceans
