Ultraviolet sensors

Abstract

UV remote sensing instruments are used to measure atmospheric ozone at near and middle UV wavelengths and to measure airglow and auroral emissions at far UV wavelengths. Ozone measurements made from the ground, from balloons and rockets, and from space use the absorption of sunlight in Hartley and Huggins bands of ozone. Total column amounts are measured from the ground using monochromators. The vertical distribution of ozone is measured with interference filter photometers on rockets and balloons. Both total column and vertical ozone distributions are remotely measured from satellites using filter photometers and spectrometers that view the sunlit nadir atmosphere or the limb.
