Multivariate objective analysis of temperature and wind fields

"This paper describes the design of an objective analysis system based upon the statistical optimum interpolation principles of Gandin (1963). The proposed analysis system interpolates values of meteorological variables to grid point locations. The analysis system is multivariate in that horizontal wind observations are used in the analysis of the temperature field and vice versa. The thermal wind relationship is used as a weak constraint. Moreover, the analysis scheme is three-dimensional. Analysis may proceed directly to model sigma surfaces (or any other desired analysis output surface) from observations distributed in three dimensions. Finally, the analysis scheme will make allowance for the various error levels of the heterogeneous observational data base in a rational and systematic way in producing the final analysis"--Introduction.
