The "Eboli Borgo Cioffi" permanent weather station is active from July 2002. It's an infrastructure of absolute importance to national and european level because it aims to research and monitoring of the interactions between agriculture and the atmosphere. This station located at 36,48 m asl permits to collect data on budget of local and regional carbon and nitrogen and air quality, with connection with the aerial and remote sensing measurements. Monitoring is continuous and carried out by different measurement platforms and sensors and transducers for in situ measurements and remote sensing. 1 .
