I'm trying to model the possble average world temperature for any given day of the year, for planets at varying distances from a star and composed of multiple materials in different quantities for an online game I'm helping develop.
basically each planet's composition is simplified to land (anything that doesn't fit somewhere else, iron (makes up the core), Carbon and Carbon dioxide, oxygen, atmopsheric toxins and surface water (i have NOT included humidity, though i might, right now it is too complex for my liking). if have approximated most of my proportions to the real world, so if percentages were used to help me with these equati
ons that would be great.. if not, then i'll be happy with whatever you can give me, and i'll convert it to game scale on my own...
here's what I'm trying to do:
1) an equations that models how much energy is given to a planet based on it's distance from a star with an elliptical orbit.
*so far i can do the ellipse equations... i just don't know how quickly the sun's energy falls off and how much it puts out in the first place... also if it can allow for differences in star size, that would be very cool.
this makes question 1 turn into the equation for the TIME OF YEAR and how that effects the energy a planet recieves, NOW i need something that determines how much of that energy is going to effect the temperature (remember this is average world temp.. so i hope that makes it easier)
2) modeling how materials in a planet effect how the star's energy increses it's temperature and how quickly that heat escapes...
*right now i have water act as a large buffer and keep the temp from fluctuating (decreases the range of a random number i tact on the end of the time of year equation), then % Carbon Dioxide increases possible temp, and also total planet sie also acts as a buffer the same as water and decreases the fluctuations.
my main problem is that i can make the equation equal what i want it to on an ideal earthlike planet, but if i change the planet variables around or the star sor the star size, it all seems much to unreasonable... so i decided that it would be easiest to model it off the real thing, using real variables... i don't know all the greenhouse gas types and i don't know all the factors that can effect a planet's temperature, so if you feel I've OVER simplified a planet's composition or whatever, then feel free to include that as one of the factors in an equation or if you think I've put something in that doesn't have a large impact then i'll take it out, if works well...
i CAN write the equations with the mistakes I've made and everything to give you a better starting point, but it was just that the numbers in them are based on the scale of the game, and are often not realistic. also as aforementioned, they haven't worked and have silly mistakes in them. i can also explain how things are scaled in the game, if you think that would help. (though it might take a long post to explain )
thx, bliss
p.s. I figured this was the most appropriate place to write this thread.. sorry if it’s not
