...This transport was much too strong in ERA-40, with successive layers of moist and dry air reaching 30 hPa only some three months after they leave 100 hPa (Figure 19(a) in Uppala et al., 2005)....

...Uppala et al. (2005) have explained the various difficulties encountered in ERA-40 with the assimilation of humidity information, which led to excessive rainfall over tropical oceans and a generally poor representation of the global transport of moisture in the atmosphere....
