Interpolations from the climatology were made using combined empirical orthogonal functions and objective mapping. Comparisons are made with independent measurements, taken in 1987, of temperature and salinity at 15?S. Temperature and salinity fields between the surface and 300 db along the 15?S section are predicted with an uncertainty sufficiently small to display significant differenccs in temperature and salinity related to El Ni?o of 1987. The 90?W pseudosection is a forecast of a synoptic section to be obtained as part of WOCE in 1992. Explicit values for the smallest temperature shift with depth that could be detected are produced. %N 6 %P 631-645 %V 5 %D 1992 %R 10.1175/1520-0442(1992)005<0631:COSACM>2.0.CO;2 %L epprod3535
