Descrizione
Within the ITINERIS project (WP 4 – Atmosphere), significant progress has been made in upgrading the OGS PA-34 Seneca III research aircraft to host advanced aerosol and meteorological instrumentation, compliant with ACTRIS standards. The activity focused on the procurement, calibration, and integration design of a comprehensive payload, including an isokinetic sampling inlet, a microphysical package (CPC, SMPS/FMPS, APS/OPC), an optical suite (aethalometer AE33, nephelometer Aurora 3000), and a high-frequency meteorological probe (AIMMS-30). Mechanical, electrical, and aerodynamic customizations were studied in detail, resulting in a dedicated power distribution system, optimized inlet and probe placements, and modular racks for cabin payload. The certification pathway has been defined, and an application for Major Change was submitted to EASA in May 2025, paving the way for full approval and flight testing beyond the project’s timeframe. This work represents a substantial step forward in reinforcing Italy’s capacity to contribute high-resolution, vertically resolved aerosol observations to the European airborne research infrastructure. The collaboration between CNR-ISAC and OGS ensures continuity towards operational deployment and scientific exploitation in international campaigns.
