The solar cycle effect on the atmosphere as a scintillator for meteor observations
We discuss using high solar cycle atmospheric conditions as sensors for observing meteors and their properties. High altitude meteor trails (HAMTs) have sometimes been observed with HPLA (High Power Large Aperture) radars. At other times they are not seen. In the absence of systematic studies on thi...

We discuss using high solar cycle atmospheric conditions as sensors for observing meteors and their properties.
