Returns the value of the CLEAR-1 night turbulence profile given altitude above sea level in meters. CLEAR-1 night is only defined from 1230 m to 30 km altitude, however, this function will return values for altitudes lower than 1230 m and higher than 30 km. The values below 1230 m are an extrapolation of the model form between 1230 m and 2130 m. The values above 30 km are an extrapolation of the model form between 10.34 km and 30 km.
