Abstract

Descriptions are given of major errors which appear in several published curves showing atmospheric attenuation at frequency intervals between 10 and 1000 GHz. Three cases are discussed, two for clear-air conditions and one for fog. In one example, the attenuation at 4 km elevation has been mislabeled as 9150 km (or 30,000 feet) for the 10 to 400 GHz range. This error has appeared in several journal articles, vendors' catalogs, short-course notes, and a recently-published book. In a second case the attenuation peak near 22.3 GHz (due to water vapor absorption) has been plotted at 20 GHz. The third case deals with an error pertaining to attenuation in fog for frequencies between 10 and 1000 GHz. Specific information and corrections are given for all three cases. The net result of these errors is that development of sensor and communications applications has been impeded because the errors usually make atmospheric losses appear to be greater than they really are.
