The software is a MATLAB function for prediction of atmospheric temperatures in Nigeria. The function is developed by method of neural network training of 3-dimensional atmospheric temperature data obtained from the COSMIC (Constellation Observing System for Meteorology, Ionosphere, and Climate) mission. The required inputs are: Year, DOYc, DOYs, UTc, UTs, altitude, latitude, and longitude, in that order. where: DOYc=cos((2*pi*DOY)/365.25); DOYs=sin((2*pi*DOY)/365.25); UTc=cos((2*pi*UT)/24); and UTs=sin((2*pi*UT)/24); [DOY is day of the year, and UT is hour of the day in universal time] The output is atmospheric temperature in degree Celsius.
