The basic idea of the simulation of snow height is the calculation of the temperature range differences. If the temperature logger is covered by snow, the range difference of the temperature should not go beyond a certain limit, because snow cover works as an isolator for the day temperature range. The temperature loggers are positioned in different heights, e.g. 0, 15, 30,…,135 cm. The temperature measurement is continuous during the season. The intervals of measuring should be as small as possible, e.g. 10 minutes. The results are approximated by the method of the degree-day-factor which gives the simulated snow height. These calculations are combined in a package in R. The package will be available here in the next time.
