Of sure the problem here is unsolved because I suppose the temperature and pressure changes during time. What I have found so far is calculation of solar radiation written in Visual Basic - it is xls table (Excel) ecy.wa.gov/programs/eap/models/solrad.zip. I don't need include winds into the calculation. The values are important in vicinity of terrain, mountains and hills. So I need to add some values to the map so when the aircraft flies it can accept some temperature changes. The game is not simulator it is just game. I would like to use the calculation for game, to generate air temperatures for map. However I cannot use these results to calculate temperature. I know that the formulas for calculation of the sun position or solar radiation are complicated but maybe there are source codes/programs which can do that? So I could use such program to calculate what I need? I have found SolTrack (C/C++) on SourceForge which calculates various data like rise time, transit time, azimuth, altitude, ecliptic longitude, latitude, right ascension, declination. I expect that the formula for calculation of the temperature would depend on sun position or even solar radiation. H is height in meters` result is in Pascals. The formula based on NTP (Normal Temperature and Pressure) to calculate pressure. I would like to calculate (estimate) air temperature at given time, location and altitude.Īll I have is air pressure for 20☌.
