The influence of temperature variations from –10 to +20 °C and of the volumetric wetness on the dielectric and emissivity behavior of reindeer lichen (moss), leafy moss, sphagnum, and peat in the microwave range has been investigated. The dependence of the dielectric and emissivity behavior of vegetation on temperature and volumetric wetness has been determined. The temperature dependencies of refractive indices of living and dead vegetation have been demonstrated to differ.
