Abstract
Lowest observed frequency (LOF) and maximum observed frequency (MOF) s patial-temporal correlation data for midlatitude long-distance paths a re presented. The possibility of improving LOF and MOF forecasting acc uracy for links without diagnostic systems by means of linear regressi on methods and a semiempirical ionospheric model is investigated, and a comparison is made of the effectiveness of providing HF communicatio n frequencies on the basis of longterm forecasting and real-time chann el evaluation.
