Title:
Balloonborne insitu measurements of water vapor and methane with the
CHILD spectrometer
Balloonborne insitu measurements are a unique possibility to obtain
profile information about stratospheric tracegas concentrations. Altitude
resolution is on the order of a few meters. The tunable laser diode
spectrometer CHILD (compact high-altitude insitu laser diode) was flown
in fall 2002 at altitudes of up to 32 km during an ENVISAT validation
campaign.
After a short introduction to the CHILD instrument and its objectives,
this talk will illustrate the hard work and the adventure of
stratospheric ballooning, and conclude with the results of the mission
and the future possibilities.
