The Atmosphere

• is the envelope of gases that surrounds the
  Earth.

• has 5 layers that are held in place by gravity.

• keeps Earth warm and filters out harmful forms of
  sunlight.

• is made of nitrogen, oxygen, water vapor, carbon
  dioxide, and ozone.

• is important to study because it gives us our
  weather and climate.

GPM
The Global Precipitation Measurement (GPM)
Satellite will collect precipitation data from
around the world. Knowing where and how much
rain or snow falls globally is vital to
understanding how weather and climate impact both
our environment and Earths water and energy
cycles, including effects on agriculture, fresh
water availability, and responses to natural
disasters.
