| Zusammenfassung |
| For high-resolution measurements of temperature fields in the atmospheric boundary layer and the
lower free troposphere a scanning eye-safe lidar which deploys the rotational Raman technique at
355 nm was developed. To optimize the filters of the receiver for both high nighttime and daytime
performance, detailed simulation studies have been performed. The receiver is fiber-coupled to a
sequential setup of multicavity interference filters used under small angles of incidence. Examples
of nighttime and daytime measurements with the system which has a total power-aperture-efficiency
product of 0.006 W m2 are presented. Noontime temperature measurements with a temporal
resolution of 60 s result in 1-sigma statistical temperature uncertainty of <1 K up to 1 km
height and <2 K up to 2 km height. With an integration time of 60 min and a gliding average
of 750 m a 1-sigma statistical temperature uncertainty of <1 K up to 14 km height is achieved
during night. |
