NASA NTRS1985

CSIS test and evaluation

This report covers the period from February 1982 when the Centralized Storm Information System CSIS was installed at NSSFC through June 1983. CSIS has had a dramatic and positive impact on the operations of the NSSFC. The value of CSIS in improving the level of severe storms forecasting is evaluated. The following CSIS components are examined: (1) hardware; (2) data acquisition; (3) data storage and retrieval; (4) forecaster-machine interface; (5) user training and requirement; (6) system relibility; and (7) software documentation.

Lessons learned from the CSIS

A discussion is presented of the Centralized Storm Information System (CSIS), a joint effort by several organizations including NASA and the National Weather Service, which has been developed to aid the forecaster in evaluating weather data. The CSIS was developed to provide a handling, analyzing, intercomparison, and display system for real-time data from all available sources. The CSIS hardware and software, the impact of the CSIS, and the initial experience gained following the implementation of the CSIS are examined. Several general insights learned from this interactive processing system are examined in detail, including the benefits of an evolutionary bottom up rather than top down design approach, the crucial nature of scheduler function to any real time system, the recognition that meteorological interactive terminals requirements are different from image processing terminals requirements, and the knowledge that forecasters generate a large peak load on computer resources.
