Abstract:
For thirty years, the European Research Infrastructure IAGOS has been equipping commercial aircraft with instruments to monitor the composition of the atmosphere on long-haul flights around the world. The aircraft measure a number of chemical species, meteorological parameters, and cloud particles at cruise altitude in the upper troposphere/lower stratosphere and during landing and take-off at many international airports. IAGOS follows an open data strategy and therefore, all data including added-value products are openly and freely accessible on our data portal www.iagos.org.
The in-situ data on chemical composition of the atmosphere collected by IAGOS is used in the routine validation of the forecasts and analyses from the Copernicus Atmosphere Monitoring Service (CAMS). This evaluation by IAGOS now covers the CAMS global and regional forecasts for ozone, carbon monoxide, and NOx, and the CAMS global greenhouse gas forecasts for CO2 and CH4. Water vapour and relative humidity forecast data are also provided for specific use.
We will describe how IAGOS works and demonstrate its scientific impact by few highlight cases.
