TEMPERATURE OF REGOLITH IN COLD TRAPS ON THE MOON A.A. Berezhnoi Sternberg Astronomical Institute Moscow, Russia The hypothesis of the existence of the lunar ice in cold traps was stated in (Watson et al., ... Arnold, 1979) estimated the mean temperature on the surface of lunar cold traps as 40-90 K. We plotted the dependence of regolith mean temperature on depth for these two values of mean temperature on the surface (see figure 1). ... Arnold J.R. Ice in the lunar polar regions, J. Geophys. ...
