A Computerized System for the Reduction of Middle Atmospheric Electrical Conductivity Data.

摘要

A computerized system for the reduction of middle atmospheric electrical conductivity data obtained by either blunt probes or Gerdien condensers is developed in this report. This particular system uses the Digital Equipment Corporation (DEC) PDP 11/10 minicomputer interfaced with the DEC LPs11 Laboratory Peripheral System, DEC LA 36 writer II, Hewlett Packard HP 3960 Instrumentation Recorder and Tektronix 603 Storage Scope. Assembly Language and FORTRAN IV programs were developed under the DEC RT-11 operating system to perform data digitizing, acquisition, storage, display, processing and finally printing out the results. The conductivity values from the computerized data reduction system were found to be consistent with those obtained by manually scaling the demodulated data waveforms from a strip chart (the method previously used for reducing the data). In fact, the computerized system is believed to be a more accurate and reliable technique. The method was also observed to enhance the range of sensitivity, i.e., the altitude region over which data can be reduced from a particular experiment. (Author)
