The temperature at 10000 FT is in agreement with the temperature in the International Standard Atmosphere. The layer between 16000 and 18000 FT is absolutely unstable Assuming that the MSL pressure is 1013.25 hPa the true altitude of an aircraft would actually be higher than the indicated altitude. The height of the freezing level over the station is approximately 12000 FT.
