Abstract: During GARP Atlantic Tropical Experiment (GATE), temporal and cospatial measurements on meteorological parameters were made. it is necessary that such measurements be pooled to obtain an optimal estimate. This paper presents ...

Abstract: A procedure for determining vertical wind profiles using Omega signal phase information from any number of Omega stations (at least three) is given. A statistical method of smoothing the phase data is presented and weighted ...

Abstract: A simple arithmetic mean, when the observations are correlated, is not the optimum estimate of the population mean. Such is usually the case when the observations are taken from a stationary time series. The variances of ...

Abstract: The Omega navigation system will be used during FGGE to derive vertical profiles of horizontal wind field. The aircraft dropsonde system and the shipboard Omega system will be used for the purpose. Since considerable effort ...

Abstract: This paper derives formulas for the application of nonlinear least squares. The need for doing statistical error analyses before undertaking any system development is pointed and formulas are derived to compute the covariance ...

Abstract: A generalized hyperbolic navigation system using Omega signals is defined. For three stations this system is shown to be equivalent to the ordinary hyperbolic navigation system. It is shown that the velocity and position ...

Abstract: The National Center for Atmospheric Research has developed a new radiosonde system CLASS (Cross-chain LORAN Atmospheric Sounding System). The sounding data acquired by this system are nonstationary with time dependent mean ...

Abstract: It has been known that the Loran (Long Range Navigation) system can accurately provide a finescale structure of winds. However, this capability could not be widely adopted because of the limited coverage of this system in ...

Abstract: Properties of the optimal combination scheme for several vector estimates are developed for correlated estimates having common ensemble mean. Classic optimality properties of a linear combination of estimates from separate ...
