Abstract

Differential absorption lidar (DIAL) using excimer lasers or excimer-pumped Raman lasers in the UV region is a powerful tool for detection of the atmospheric ozone in a wide-altitude range up to 50 km.^1-3 However, daytime observation is made difficult by the Interference of intense solar radiation. Since the solar radiation at shorter wavelengths than ~310 nm is sharply cut off by stratospheric ozone, we can expect to obtain a good SNR even in daytime observations at these wavelengths. The concept of the solar-blind effect in lidar was first used with a Raman lidar for the detection of water vapor.⁴
