Overview HIBISCUS Small balloons and sondes : the local view

• Small balloons : several instruments on the same flight train

– Lightweight (10 to 40 kg), low consuming, small size, robust instruments

– Combination of meteorology, GPS location, clouds, tracers, chemistry, H2O, electric field

• 2 x 10ZL (10 000 m3), 120 kg at hook, ascent/descent up to 30 km

• 4 x 3SF (3000 m3), 170 kg at hook, daytime ascent and natural night-time descent through the TTL (22km => 14km)

• 10 backscatter, 12 ozone and 2 UV radiation sondes
