Da. De Wolf et al., Reflectivity and attenuation at millimeter to infrared wavelengths for advection fogs at four locations, J APPL MET, 38(1), 1999, pp. 126-131
Recent drop size distribution data from four advection fog sites are reanal
yzed for the purpose of predicting millimeter-wave and infrared to visible
wavelength reflectivity and attenuation coefficients in such fogs. A gamma
drop size distribution model is shown to be an adequate fit to measured dis
tributions of typical fog drop diameters. Conclusions are drawn with respec
t to the relationships between the reflectivity and the attenuation to the
liquid water content. A possible method is outlined for using ground-based
measurement of liquid water content for the purpose of predicting arbitrary
slant-path reflectivity and attenuation at the smaller wavelengths.
