Question

Global Precipitation Measurement (GPM) is a tool scientists use to forecast weather. Which statements describe GPM? Check all that apply. It is a computer model used to predict weather. It is a satellite that collects data about rain and snow. Its orbit covers 90 percent of Earth's surface. Its orbit covers 70 percent of Earth's surface. The sensors measure visible light. The sensors measure microwaves.

Answer 1

The correct answers are:

• It is a satellite that collects data about rain and snow.

GPM is part of NASA's Earth Systematic Missions program and its function is to track precipitation from space with satellites and to provide accurate information of the time, place an amount of rain or snow anywhere in the world.

• Its orbit covers 90 percent of Earth's surface.

 GPM has unique perspective on measuring precipitation from space because of their collected satellite retrievals.

• The sensors measure microwaves.

GPM Microwave Imager (GMI) is a sensor that observes the microwave energy emitted by the Earth and atmosphere, so it improves the accuracy of rain and snowfall estimates.
