- For the hottest month of the year at the proposed airport site, the monthly mean of the average daily temperature is 39°C. The monthly of the maximum daily temperature is 48°C for the same month of the year. From the given information, the calculated Airport Reference Temperature (in °C), isIn order to compute the airport reference temperature and the standard temperature with respect to elevation, the monthly mean of average daily temperature and the monthly mean of the maximum daily temperature of the hottest month of the year is found to be 31° C and 42.5° C respectively. The airport reference temperature is:The monthly mean temperature of maximum daily temperature and monthly mean of average daily temperature of the hottest month of year are 52 degree Celsius and 40 degree Celsius respectively. Then airport reference temperature is?
