Abstract

The European Research Infrastructure IAGOS (In-service Aircraft for a Global Observing System; www.iagos.org) responds to the increasing requests for long-term in-situ observations in the UTLS in particular and across the troposphere in general by establishing a monitoring infrastructure based on the use of commercial passenger aircraft as measurement platform.

IAGOS operates instrumentation for measuring gaseous species (O3, CO, CO2, CH4, NOx, NOy, H2O), aerosols and cloud particles. By end of 2013, the participation of 5 globally operating airlines is planned. The envisaged involvement of a US airline will significantly improve the density of the network over North America, moving IAGOS closer to its goal of full global coverage. The talk will summarize the current status of the research infrastructure. Based on recent results the additional benefit of an US airline participation will be highlighted. Particular emphasis will be put on the ongoing development of new aerosol instrumentation of IAGOS.
