Erratum to “Atmospheric Humidity Sounding Using Differential Absorption Radar Near 183 GHz” [Feb 18 163-167]

In
[1, Fig. 5]
, the assumed atmospheric conditions were incorrectly stated for the curve showing the millimeter-wave propagation model of excess attenuation at frequencies with respect to 193 GHz. Rather than being for 91% relative humidity (RH) and 289 K, as was stated in
[1]
, the model curve in
[1, Fig. 5]
was for 50% RH and 289 K. (The experimental measurements are unaffected.) The figure is reproduced here as
Fig. 1(a)
, now with correct labeling.
