| Zusammenfassung |
| A new method for measuring air temperature profiles in the atmospheric
boundary layer at high spatial and temporal resolution is presented. The
measurements are based on Raman scattering distributed temperature sensing
(DTS) with a fiber optic cable attached to a tethered balloon. These data
were used to estimate the height of the stable nocturnal boundary layer. The
experiment was successfully deployed during a two-day campaign in September
2009, providing evidence that DTS is well suited for this atmospheric
application. Observed stable temperature profiles exhibit an exponential
shape confirming similarity concepts of the temperature inversion close to
the surface. The atmospheric mixing height (MH) was estimated to vary between
5 m and 50 m as a result of the nocturnal boundary layer evolution. This
value is in good agreement with the MH derived from concurrent Radon-222
(222Rn) measurements and in previous studies. |
