501 DETERMINATION OF NATURAL HAZE SIZE DISTRIBUTION FUNCTIONS FROM OPTICAL DEPTH OBSERVATIONS David A. Rainey, Warner K. Reeser, William E. Marlatt Colorado State University ABSTRACT Work by Phillips and Twomey has provided a technique for solving the Fred holm integral equation of the first kind, which arises frequently in remote sensing problems. This technique has been applied widely to the problem as determining natural haze size distribution functions. Determination of a distribution function is made using optical depth measure ments for the earth’s atmosphere observed at the ground. This process yields an average distribution for an aerosol layer one kilometer in height. INTRODUCTION A principle problem encountered in studies of the effect on attenuation of solar radiation in the atmosphere by natural hazes reduces to that of characteri zing the haze by composition and size distribution. The standard approach to this problem is to solve the integral equation which gives the extinction coefficient for the layer. This is equivalent to inverting the linear system given by the numerical quadrature form of the integral. Phillips (1962) proposed a method of solution in which the solution is picked from a family of solutions by placing a constraint of the error function of the data and subjecting the solution to a smoothness criterion. Twomey (1963) provided a form of Phillips solution that did not require the quadrature matrix to be square. The method was applied to horizontal extinction measurements over Chesapeake Bay by Yamamoto and Tanaka. Their work showed that natural hazes are fairly well approximated by a power law. The method used by Yamamoto and Tanaka is applied here to optical depth data where extinction is obtained by assuming that the optical depth measured is the extinction of a haze of one kilometer in height. As in other studies of this type, Mie scattering is assumed, METHOD The extinction coefficient, 3, may be given as a function of wavelength, A, by the integral equation 3(A) = tt /°° r 2 N(r)Q ext (x, m(A) }dr 0-1 ^ -3 -1 where the solution N(r) is the particle size distribution in cm Qim) , r is the particle radius, and x = 2-nr/X is the Mie size parameter. The factor is
