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) Conclusion
