RESUMO

The efficient use of agricultural resources requires monitoring and correct forecasts of climatic factors. These monitorings must be made through analysis of measures of climatic elements (known as climatological data) such as temperature, precipitation and air humidity. The integration of data from various sources enables better characterization of climatic behavior, helping to plan agricultural activities and decreasing the chances of crop losses. The objective of this dissertation is to study the problems related to climatological data integration and to specify an architecture that solves these problems. The proposed architecture deals with data homogenization, quality evaluation and data availability. Descriptive metadata facilitate data access, and results of quality evaluations provide additional support to the decision process. This work was validated through partial implementation of the architecture for a climatological monitoring project developed in the Brazilian Agricultural Research Corporation (EMBRAP A). The main contributions of this research are: (1) study of problems inherent to climatological data integration; (2) study and survey of questions associated with climatological data quality evaluation; (3) specification of a climatological data integration architecture and (4) validation of the architecture through partial implementation for a real case study
