Abstract
A meteorological lidar performs highly precise meteorological observation by primarily removing elastically scattered light and by detecting rotational Raman-scattered light without filtering it out. The meteorological lidar according to embodiments measures scattered light of a laser beam, and includes: a diffraction grating diffracting rotational Raman-scattered light contained in scattered light in accordance with the wavelength of rotational Raman-scattered light; a detector detecting the diffracted rotational Raman-scattered light; and a removing element primarily removing elastically scattered light of a specific wavelength contained in the scattered light.
