Abstract: Pulsating aurorae are proposed as a source of the infrasonic waves associated with geomagnetic activity reported by Chrzanowski et al. One of the most plausible mechanisms for generating these long period pressure waves ...

Abstract: Based on the Nimbus-7 solar backscattered UV-radiation (SBUV) data which are free from the instrumental background noise (dark-current) produced by magnetospheric particles, it is found that the southern winter hemispheric ...

Abstract: A technique for determining cloud-top height by means of backscattered ultraviolet (BUV) solar radiation is presented. Cloud-top heights can be inferred using this technique if both the BUV radiance and its degree of ...
