چکیده
Abstract The occurrence characteristics of 150-km echoes in low-latitude regions are studied using the Equatorial Atmosphere Radar (EAR) Indonesia. long-term observation by EAR enables us to study statistically. It is shown that rate observed shows a semiannual variation with two peaks solstices and negative correlation both EUV flux $$\Sigma$$ Σ Kp index, is, solar geomagnetic activity. Geomagnetic activity correlates one day after when was measured. However, always low during high period regardless While seasonal dependence consistent previous studies, this first time reported.

On the characteristics of 150-km echoes observed in the Brazilian longitude sector by the 30 MHz São Luı́s radar
We present long-overdue details about the intensity and spectral characteristics of 150-km echoes observed by the São Luı́s radar in Brazil. The São Luı́s observations show that the echoes usually come from multiple scattering layers that descend in altitude before local noon, and ascend during afternoon hours, similar to what has been found in observations made in other longitude sectors. The la...
متن کاملBird Migration Echoes Observed by Polarimetric Radar
Weather surveillance radars observe clear-air radar echoes (CAE); aerial biota and irregularities in atmospheric refractive index caused the echoes. Using weak returns of atmospheric CAE, the radars have been applied to wind findings in a short radar range in a fair weather, in particular S-band radars. Long wavelength radars perform good to observe air motion, because a detectable turbulent sc...
