STRAPOLETE Campaign (2009)
STRAPOLETE (an acronym derived from the three french words for Stratosphere, Polar and Summer) was a stratospheric balloon launch campaign carried out between August and September 2009 from Esrange launch base, near Kiruna, Sweden. It was funded by French agencies ANR, CNES and IPEV, as a contribution to the International Polar Year.
The objective of the campaign was to perform measurements of the main characteristics of the summertime arctic stratosphere which remained largely unexplored as the vast majority of the balloon launch campaigns in the past were focused on the study of the polar vortex associated with the winter ozone loss processes.
The campaign was under management of the balloon group of the French Space Agency (CNES) and counted with the participation of several european research institutions.
The instruments deployed during the campaign included UV-visible and infrared instruments, remote and in situ sensing embarked spectrometers which provided detailed information on vertical distributions of more than fifteen chemical tracers and reactive species from the upper troposphere to the middle stratosphere. Also a number of in situ optical aerosol counters, a UV-visible remote spectrometer for the aerosol extinction and a photopolarimeter provided information on the nature and size distribution of the stratospheric aerosols.
A total of eight flights were performed using balloons that ranged from 35 000 m3 to 400 000 m3 of volume transporting scientific payloads from 90 kg to 500 kg. Also during the campaign CNES performed two technological flights to test new balloon systems.
