WebThe optical window is a range of wavelengths that are not blocked by the earth's atmosphere.The window runs from around 300 nanometers (ultraviolet-B) up into the range the human eye can detect, roughly 400–700 nm and continues up to approximately 2 μm. Sunlight mostly reaches the ground through the optical atmospheric window; the sun is … WebDifferential Optical Absorption Spectroscopy (DOAS) is a non-intrusive optical technique used to detect and quantify trace gases in the atmosphere. DOAS works by measuring the attenuation of light as it passes through the atmosphere, and identifying the characteristic spectral signatures of the target gases.
