| Zusammenfassung |
| A new Raman lidar for unattended, round-the-clock measurement of vertical
water vapor profiles for operational use by the MeteoSwiss has been
developed during the past years by the Swiss Federal Institute of
Technology, Lausanne. The lidar uses narrow field-of-view,
narrowband
configuration, a UV laser, and four 30 cm in diameter mirrors, fiber-coupled
to a grating polychromator. The optical design allows water vapor retrieval
from the incomplete overlap region without instrument-specific
range-dependent corrections. The daytime vertical range covers the
mid-troposphere, whereas the nighttime range extends to the tropopause. The
near range coverage is extended down to 100 m AGL by the use of an
additional fiber in one of the telescopes. This paper describes the system
layout and technical realization. Day- and nighttime lidar profiles compared
to Vaisala RS92 and Snow White® profiles and a
six-day continuous observation are presented as an illustration of the
lidar measurement capability. |
