Relationships Between Reflectivity, Attenuation, and Rainfall Rate Derived from Drop Size Spectra
Abstract
One hundred fifty-four tables are presented which show the relationships between rainfall rate, radar reflectivity, and attenuation. These parameters have been calculated from drop-size distributions obtained by the drop camera technique. Calculations of attenuation and reflectivity were made using the Mie theory for wavelengths of 10.0, 4.0, 3.2, 1.87, 0.86, and 0.43 cm. Logarithmic regressions have also been calculated for these parameters. These tables have been prepared for data obtained from Illinois, Florida, Oregon, Majuro, Alaska, Indonesia, New Jersey, and North Carolina. Other tables showing the relationships of the drop-size medium volume diameter and liquid water content to reflectivity are presented for New Jersey and North Carolina at 4.0 and 3.2 cm. A table of the relationship of 4.0-cm attenuation to 3.2-cm reflectivity is included for New Jersey and North Carolina.
