                      of a high precision in-situ hygrometer for the research
                      airplane $\textbf{HALO}$ which uses the Tunable Diode Laser
                      Absorption Spectroscopy. To provide tropospheric and
                      stratospheric measurements between $\textbf{2 ppmv}$ and
                      $\textbf{10000 ppmv}$ two different lasers are implemented:
                      One for high mixing ratios up to $\textbf{10000 ppmv}$ in
                      the $\textbf{1,4 $\mu$ m}$ absorption band of the wate
                      molecule and one for low mixingratios between $\textbf{2
                      ppmv}$ and $\textbf{400 ppmv}$ in the $\textbf{2,6 $\mu$m}$
                      ground vibrational band. For noncontact measurements of gas
                      phase water an open path cell with two absorption paths has
                      been developed. In contrast to the common Herriott setup of
                      a cell with multiple absorption paths this cell has been
                      designed as a White cell to include a direct fiber coupling.
                      By using a computational based optimization for the optical
                      absorption pths the disruptive interfering effects could be
                      reduced below a level of $\textbf{266 ppmv}$ which is given
                      by the used lasers. Due to the technical difficulties by
