Examination of various techniques for measuring wind velocities using clear-air radars, with emphasis on vertical wind measurements
(University of Colorado, 1998)
In this work, I examine various techniques for measuring wind velocities using clear-air radars. Special emphasis has been given to the vertical wind measurements. All the observations were obtained in the lower atmosphere ...
Inclination of the geomagnetic field measured by an incoherent scatter technique
(American Geophysical Union, 1971-01-01)
A technique to measure the direction of the geomagnetic field by using incoherent scatter techniques is described. The technique has been used to measure the inclination of the magnetic field at the Jicamarca Radar Observatory ...
