Planning
Four balloon flights are planned; two early flights in vortex conditions and two late flights in springtime to cover the vortex to springtime changes. The two sets of flights each consist of one gondola with instrumentation for in situ measurements and one gondola for remote sensing. These two methods are complementary as in situ measurements generally result in a better altitude resolution whereas remote sensing observations cover a larger spatial area.
