Obtain Weather Data with Data Warehousing

The main function of most current forecaster´s workbench is data access. They are usually an integrative graphics system to show the data and derived data, and give some analysis tools, and graphics manipulation tools, we have three problems with such systems. 1. Although the system can provide many data (over 2 GB, several thousand fields one day), forecasters only use little of them (less than 1 %) in operational forecast. 2. Massive storage system is developing in Iran ,we will get many history data in operational forecast, how to make our system to use these data? 3. Many kinds of special observation system are developing, such as AWS, profiler, GPS/Met, storm lightning locator, etc. They are very useful for public service, but we must have a flexible data manager to use them in operational forecast. The most serious problem is the first one above. Data warehouse is a new generation of decision support system (DSS). It may provide a good solution for the problems.
