The Morphology of Geomagnetic Micropulsations, much as a few tens of gammas. Periods range from about 0.1 sec to 10 min. Most work has been done in the lower frequency end of this range, very little being known at the higher frequencies from 3 to 10 Hz. In recent years, mainly as a result of the greatly increased number of continuous observatiocyanosis 发表于 2025-3-25 11:31:21

The Morphology of Geomagnetic Micropulsations,lier classification was too simple and that in reality there exist many more different types or variations of the earlier, broader classification. This classification divided micropulsations into three categories, pc’s, pt’s and pg’s, which will be defined later.新字 发表于 2025-3-26 17:31:32
