The developed system, called AISLE, is an adaptive, intelligent tool for supporting advanced information management services. Its main characteristic is the provision of decision support and information diffusion abilities through electronic services to several users with diverse needs. Specifically, software agents are in charge of integrating and managing environmental data recorded by field sensors or other monitoring devices, along with their diffusion to a wide range of end-user applications, such as environmental databases, terminal applications, or public information services over the internet. The system has been demonstrated in two pilot cases. In the first case, AISLE has been applied for assessing and reporting ambient air quality in Valencia, Spain. In the second case, AISLE was used for monitoring weather conditions in Cyprus. Contact email addresses: ionathan@ee.auth.gr (I. N. Athanasiadis) mitkas@eng.auth.gr (P. A.
