The availability of appropriate meteorological and agrometeorological databases is a major prerequisite for studying and managing the processes leading to agricultural and forest production. The building of databases for meteorological, phenological, soil, and agronomic information is inevitably a major priority. The key steps to database management are pertinent climate and agrometeorological data processing; data quality control; data archiving; timely access to data; and of utmost importance, information dissemination for use in both agricultural research and operational programs.
