This report describes the results of validation of the surface meteorological data collected by the ships in the A/B-, B-, and C-scale arrays during the 1974 GARP Atlantic Tropical Experiment (GATE). Mean meteorological fields for each of the three GATE observation phases were analyzed in order to determine the average biases in the measurement of each variable on each ship. Charts of resulting mean values and tabulations of the biases are presented. Included also are updates and corrections to earlier reports issued as part of the GATE Convection Subprogram Data Center, and documentation pertaining to the archived data.
