It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.
The seasonal dependence of the probability of large-scale traveling ionospheric disturbances is analyzed based on nighttime ionospheric parameters measured over Almaty during 2000–2007, as well as the dependence of annual average probabilities of their occurrence on the sunspot cycle. The behavior of these probabilities is compared with magnetic activity.
