This paper is concerned with the state of the art in the calculation of electromagnetic wave scattering by hydrometeors. Four methods currently being used are briefly described (point-matching, T matrix, unimoment, and Fredholm integral equation), and aspects of their computational implementation are reviewed and compared. The ranges of validity of three types of approximation are discussed—those with respect to size, orientation, and frequency. Finally, scattering patterns from various sizes of spheroidal raindrop at 11.7 GHz are briefly discussed.
