A model of the geoelectric structure of the frozen soil thickness is proposed, including a layer of their transitional permafrost. Monitoring of changes in this layer is proposed to be carried out by observing seasonal changes in the parameters of geoelectric sections, obtained as a result of radioimpedance or RMT sounding. Viewing changes in geoelectric sections over time, allows you to determine the parameters of the selected layer of transitional frost as the main ones when monitoring the state of frozen soils. An indicator of the iciness of soils is proposed. Electromagnetic emission of frozen soils occurs during intensive thawing or freezing of water in the active layer. The amplitude of the field by electromagnetic emission of frozen soils is twice as large when they melt as when they freeze. The intensity and duration of the melting and freezing of soils can be estimated by the amplitude of the field created by electromagnetic emission.
