  1. 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 SF2, Feb 13th 2004

  2. ZL2 31 Jan 20:30 - 22:30 Labs, SAOZ, SAOZ-BrO In SACZ Active Thunderstorm and heavy local rainfall 18:00 24:00

  3. ZL1 5 Feb 20:00-22:24 Dirac, SAOZ, SAOZ-BrO Active SACZ Some local Thunderstorms 18:00 24:00

  4. 21:00 SF2 13 Feb 20:16-00:30 Descartes SLS, µ Dirac, µLidar, SAW, SSS, µ SDLA Just before Strong Cold front travelling NW towards Bauru 24:00

  5. SF1 16 Feb 20:25-01:30 Falcon overpass Descartes SLS, µ Dirac, UMIST, LABS, SAW, SSS, TDLAS, AIRS Flight behind SACZ moving fast to the NW 18:00 24:00

  6. Carnaval SF4 24 Feb 20:00-00:20 Dirac SLS, µ Lidar, SAW, SSS, µ SDLA, AIRS SACZ Strong Squall line coming from the NW Heavy rainfall in the evening 18:00 24:00

  7. SF3 February 26, 20:00 02:04 Very active thunderstorms over Santa Catarina travelling fast NE, over Bauru at end of flight Feb 26 18:00 µ Dirac picture at Sunset Feb 27 00:00 LIS 22:00 Descartes SLS, µ Dirac, LABS, SAW, SSS, TDLAS

  8. DMI backscatter/ozone sondes Feb10th to Feb 24th

  9. Time evolution of Potential Vorticity during the campaign - MIMOSA contour advection 30 Jan 10 Feb 24 Feb 04 Mar Temperature deviation compared to averaged TroCCiBras sondes

  10. Conclusion • Small balloons and sondes : Combination of meteorology, GPS location, clouds, tracers, chemistry, H2O, electric field • Flights in a variety of meteorological conditions : convection, horizontal transport, lightning, .. • Flight reports available on the HIBISCUS WEB site • Most of the data in the HIBISCUS/VINTERSOL data base (zardoz.nilu.no)
