GCMD request: Exosphere

by GES DISC - ingridgs » Tue Mar 31, 2026 9:59 am America/New_York

I would like to request the addition of the keyword: EXOSPHERE.
Locations > Vertical Location > EXOSPHERE
Description:
The exosphere lies directly above the thermosphere, beginning at an altitude of approximately 500 to 1,000 km (310–620 miles) above Earth's surface, with its lower boundary called the exobase or thermopause. Its upper boundary is not clearly defined, gradually fading into the vacuum of space, and can extend as far as 190,000 km (120,000 miles), roughly halfway to the Moon, where solar radiation can push hydrogen atoms beyond Earth's gravity (NASA, UCAR).
