Title: Bug or did I miss something?
Post by: Rich.h on June 07, 2014, 09:55:55 AM
I am trying to terraform a particularly nasty planet more out of sheer will power than of actual usefulness. The main problem I have is temperature I just cannot seem to get it high enough for a zero cost colony.

The calculations are:
Surface Temperature in Kelvin = Base Temperature in Kelvin x Greenhouse Factor x Albedo
Greenhouse Factor = 1 + (Atmospheric Pressure /10) + Greenhouse Pressure   (Maximum = 3.0)

Putting that into the current planet conditions I have:
Surface Temperature in Kelvin = 62.22 x 4.39815 x 1.09
Greenhouse Factor = 1 + (3.9815 /10) + 3   (Maximum = 3.0)

When I do this I get a result of a surface temperature of 298.28k. However aurora keeps giving me a surface temperature of 203.47k.

Has there been an error in the maths on my part of is there some other factor I haven't taken into account? Obviously this temperature difference turns a zero colony world into one that needs much more.

Albedo change maybe?  No clue

The greenhouse factor cannot be higher than 3. So you have 62.22 x 3 x 1.09 = 203.46

Ah thank you I misread it to mean the maximum greenhouse pressure was 3. That clears it up though thanks.
