Lowering this value increases the length of each day) Specifies the scaling factor for the passage of time in the ARK during night time. This value determines the length of each night, relative to the length of each day (as specified by DayTimeSpeedScale.
How to change the day and night cycle?
Specifies the scaling factor for the passage of time in the ARK world during the day. This value determines the length of each day, relative to the length of each night (as specified by NightTimeSpeedScale. Lowering this value increases the length of each day) NightTimeSpeedScale=1.000000
How does the temperature vary during the day and night?
For two clear-sky days at a grassland site in southeastern Kansas, ground surface temperature and air temperature (top), downwelling (downward) solar radiation and net radiation (bottom). Notice how the net radiation goes to zero at about 19 hours past midnight and stays negative until about 5 hours past midnight.
