On Tuesday, 24th Sept, the first day flight dedicated to southern hemispheric chemistry was successfully performed. The area of interest was south- and eastward of Rio Grande towards 63°S. There aged and chemically processed air was probed in the polar vortex and in the vicinity of the polar vortex edge. The flight was coordinated with ground-based and balloon-borne ozone measurements on King George Island, Marambio Station in Antarctica and at Ushuaia.
After one day of ground maintenance, preparations for the last night flight in this part of the campaign are currently ongoing.
Yesterday night, HALO completed the fourth research flight dedicated to mountain waves above the Southern Andes. Prevailing moderate westerly to south-westerly winds triggered mountain waves and the flight crew could report “nice” up- and downward movements of the aircraft shortly after take-off along the first cross mountain section.
