| The atmosphere of Sting is composed of 22% oxygen (the same as Earth) but the overall pressure is only 0.7 atm at sea level. Thus the equivalent altitude on Earth (based on oxygen pressure) is 3km higher (ie there is the same amount of oxygen at 0km altitude on Sting as there is on Earth at 3km). |
| The basic temperature (for hex row N-4) is 13.9°C, but this is affected by a number of factors: axial tilt, eccentricity, and day and night. It can also be moderated by water (if a coastal area adjust the temperature by 1d6° up or down towards 13.9°C). The 'arctic circles' lie at about 19° from the poles, and thus include hex row N-9 (and north from here) and S-9 (and south from here).
