The meteorological data obtained under natural-icing conditions at Willow Run, Michigan, and at Mt. Washington, New Hampshire, during the 1953-54 icing season, are presented. A total of 25 icing flights were made with a B-24 airplane. During these icing flights, 156 icing-intensity measurements were obtained by the rotating-multicylinder method. A total of 84 rotating- multicylinder runs were conducted at Mt. Washington. The data presented consist of liquid-water content, mean-effective droplet diameter, droplet-distribution type, free-air temperature, pressure altitude, true air speed, type of cloud, and geographical location. The range of the meteorological conditions measured during the season is as follows: liquid-water content, 0.04 to 0.95 gm/m to the 3rd power; mean-effective droplet diameter, 5 to 36 microns; free-air temperature, -3 to +31 F; and pressure altitude, 3850 to 7550 feet. Frequency- of occurrence curves of liquid-water content and mean-effective droplet diameter are presented.
