The climate is also much affected by the inclination of the earth's surface and its altitude above sea level.

气候受地表倾斜程度及其海拨高度的影响也很大。

Because the satellite's altitude above sea level is known, the thickness of the ice above sea level can then be determined, allowing the overall thickness of the ice to be calculated.

因为该卫星的海拔高度已知，于是就能够确定海平面以上的冰层厚度，从而可以计算出冰层的总厚度。

The air pressure is also now closer to what is normal in Denver, Colorado -- the mile-high city at 5, 280ft -- than the traditionally higher, and more mountaintop-like standard of 8, 000ft above sea level, sparing fliers from the mild altitude sickness that can be experienced when flying a long distance.

It traverses oxygen-starved, earthquake-prone terrain that for most of the way is over 4, 000 metres (13, 120 feet) above sea level and rises to 5, 072 metres not far off the altitude of Mount Everest's base camp.
