In all, 115 service flights were made under this contract from various government installations throughout the country. A summary of these flights is listed in Table I (see end of text).
E. Meteorological Analysis
As one phase of this project, New York University agreed to prepare analyses of winds and temperatures in the troposphere for dates and localities specified by Watson Laboratories.
The vertical distribution of temperature from the ground up to heights of about 15 km at the time of any particular experiment was estimated from the routine radiosonde ascents which were nearest in respect to both time and space, to the site of the experiment. If the time of the experiment was within three hours of one of the twice-daily, standard hours of radiosonde observation, the temperature distribution given by such observation was assumed to have existed (within the limits of error in the method of measurement) at the time of the experiment. If the time difference was greater than three hours, a linear interpolation was made between radiosonde observations preceding and following the time of the experiment. Interpolation in space was accomplished ordinarily by assuming a linear horizontal variation of temperature.
