Global Precipitation Measurement (GPM) is a tool scientists use to forecast weather. Which statements describe GPM? Select three options.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
A
It is a computer model used to predict weather.
B
It is a satellite that collects data about rain and snow.
C
Its orbit covers 90 percent of Earth’s surface.
D
Its orbit covers 70 percent of Earth’s surface.
E
The sensors measure visible light.
F
The sensors measure microwaves.
Explanation
GPM is a satellite mission that collects information about rain and snow, rather than a computer model that predicts weather. Its orbit reaches about 65° north and south latitude, covering roughly 90% of Earth’s surface. Its instruments detect microwaves to measure precipitation; they do not rely on visible light.
