Fig. 5From: On new two-dimensional UHF radar observations of equatorial spread F at the Jicamarca Radio ObservatorySame as Fig. 4. But now the images are for times when a radar plume was generated above Jicamarca and developed vertically while drifting to the east. Therefore, the images show the spatio-temporal evolution of a radar plume during its development. The RTI map for the vertical beam, however, continued to show only weak bottomside F-region echoesBack to article page
