An approximate analytical expression is developed for the attenuation of middle ultraviolet radiation along slant paths through the atmosphere. The independent variables are wavelength, altitude of source (the detector is assumed to be above the atmosphere), angle of path with respect to zenith, and three parameters which characterize the ozone distribution. An approximate analytical expression is also developed for the scattered solar radiance seen by a satellite. Here the independent variables are the wavelength, the look angle and the sun angle with respect to the zenith, the scattering angle, and again three parameters which characterize the ozone distribution. The results based upon the formula are compared with previous studies and an experimental measurement.
