Description:
Acquisition of timely, high quality data from reasonably dense evenly distributed observing points is essential to production of accurate sequential analyses. Establishment and continuous operation of such networks are a demanding task in light of national interests, economics, technology, and geopolitical factors. Apart from the important aspects of international cooperation and comprehensive network design, increased automation at major world weather analysis centers has introduced a unique set of problems associated with total procurement, utilization, and onward dissemination of data. Due to computer sensitivity and a rigid requirement for inter-system compatibility, practically every meteorological analysis produced is degraded to some extent by the absence of essential data. At times the losses of these data have direct implications on the accurate depiction of the state of the atmosphere. Detection, investigation, and resolution of data deficiencies is essential to optimum system operation but is, at best, a complex and involved undertaking. Cause/effect relationships of data deficiencies must be determined and then followed by decision processes appropriate in dealing with the characteristics of the deficiency. Objectivity is essential in determining the reasons for data deficiencies in order to avoid initiating inappropriate action which may be resented. A review is presented of the latest procedures for evaluating data in terms of timeliness, accuracy, and completeness. Recent developments of procedures and techniques for systematically appraising the distribution and quality of global data is discussed. New involvements of the WMO in comparing the availability and quality of data at each major meteorological center throughout the world are taken into account. Procedures developed and implemented by the National Meteorological Center and Air Force Global Weather Central for minimizing data discrepancies and losses are presented.
