Knowledge-based Weather Information System

For the effective management of crop production system, Central Tobacco Research Institute (CTRI), Rajahmundry has been collecting and using weather data since 1960 in record books. Retrieval of data from these records is cumbersome and time consuming and the records are prone to damage for long period of storage. Hence, for easy storage and retrieval, a Knowledge-Based Weather Information System (KBWIS) was developed based on 10 weather parameters available in the records using. Net technology. The KBWIS not only safeguards the available meteorological data but also reduces large number of clerical operations for its retrieval. The KBWIS allows the user to add, view and modify the weather data. Hard/soft copy of the required data on any combination of weather parameters can be retrieved in the form of text along with graphs or exported to Microsoft Word. The KBWIS can also acts as an input for developing forecasting/prediction models. At present, the weather data collected from 1960 at CTRI and its six regional stations are stored and updated daily in this database. This software can also be customised by the users for storing the weather data collected by them.
