User's Manual for Computer Programs to Perform Oceanographic Vector Time Series Data Analysis and Related Graphics.
Abstract
This 'User's Manual for Computer Programs to Perform Oceanographic Vector Time Series Analysis' was prepared for the Environmental Measurements Program (Code 500) of NORDA in partial fulfillment of requirements under an Office of Naval Research Contract number N00014-78-C-0879. The software is written in Fortran IV specifically for use on the UNIVAC 1108 computer located at NAVOCEANO in NSTL Station, Mississippi. It is capable of accommodating any vector time series data, but the products are specifically directed at meteorologic and physical oceanographic data including current meter and wind data. The guidelines on this effort were that the vector time series software had to be compatible with existing FESTSA software at NAVOCEANO and that the plotting routines were to utilize the sophisticated DISSPLA software currently available at NAVOCEANO; both of these were adhered to. Both the rotary spectral and rotary cross spectral programs are designed to read directly from the FEB files of the FESTSA system. Another critical requirement was to extend the capability of the user to process records of lengths other than 2 to the nth power; this was accomplished by incorporating the mixed radix fast Fourier transform program of Singleton (1969) which is based on prime factors. This feature enables users to select records of length 2 to the 9th power, if desired, but it is not a limitation as in many other vector time series analysis programs. Subroutines are available for pre-whitening and post-coloring of data, if desired, and there are a number of data 'windows' available along with three different types of averaging: block, convolution, and a combination of the two.
