Abstract
Using radiosonde balloon data taken from sites close to the DSN tracking stations, the tropospheric zenith range effect Ap. has been computed throughout 1967 and 1968. The behavior of Ap, has definite seasonal trends which are similar in both years. With the modification of the tropospheric model, which is used to calibrate radio tracking data to include these seasonal trends, the navigational errors, produced by inaccuracies in representing the zenith range effect, may possibly be reduced by as much as 40%.
