Successful transfer flight of HALO to Anchorage, Alaska, for the next mission phase of PHILEAS.
Scientists will investigate the following research questions:
1. What are the chemical composition and microphysical properties of the gas and particulate phase of large-scale eddies which are shed from the monsoon anticyclone?
2. What are the main transport pathways (advection and mixing) and time scales of polluted and moist air from the monsoon into the extratropical UTLS?
3. How do these shed eddies impact on the extratropical UTLS, and in particular on the water vapour and aerosol budget?
