Ionosphere conditions
WebPrior to 2002, it was believed that, during unusual ionosphere activity, ionospheric spatial gradients would not be more than 5 – 10 times greater than the value of 4 mm/km that was seen as a reasonable one-sigma bound on zenith ionosphere spatial gradients under both nominal and active ionosphere conditions, even during solar maximum (see [1]).
