Craig, Richard A.
In the summer and fall of 1944, psychrometric measurements were made in the
lowest 1000 ft of the atmosphere over Massachusetts Bay. They were designed to show
vertical distributions of temperature and humidity in more detail than had any previous
observations over a comparable height range. The measuring program was carried out
under the general direction of Mr. Donald E. Kerr by members of the Radiation Laboratory,
Massachusetts Institute of Technology, in connection with studies concerning the
propagation near the sea surface of radio waves of the order of centimeters or a few
meters in length. The meteorological measurements were desired because they yielded
information about vertical distributions of refractive index of air for radio frequencies.
The vertical distribution of refractive index is of great importance in the propagation
problem (Sheppard, 1946), that in the lowest 1000 It being of primary significance for
the study at the Radiation Laboratory.
