Remote daytime measurements of tropospheric temperature profiles with a rotational Raman lidar
Abstract:
Tropospheric temperature profiles have been measured at daytime with a rotational Raman lidar. The lidar operates in the solar-blind spectral region with KrF laser radiation that is Raman shifted in hydrogen to 276.787 nm. This wavelength corresponds to the resonance absorption of a thallium atomic-vapor f ilter that is used to suppress the large elastic-backscatter signal. The rotational Raman signal is analyzed with an echelle grating spectrometer that separates spectral regions with different temperature sensitivities in both the Stokes and the anti-Stokes Raman spectra. Simultaneously, profiles of water vapor and ozone can be determined by means of vibrational Raman backscattering.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
