NASA | Scanning a Snow Storm

The video discusses a rare late-season East Coast snowstorm observed by the GPM satellite shortly after its launch in 2014. It highlights GPM's ability to measure various types of precipitation, including light rain, heavy rain, and snow. The video explains how GPM provides valuable data on cloud tops and precipitation, offering new insights into winter storms. Additionally, it describes the GPM constellation, a network of international satellites that monitor global precipitation patterns.

What was the primary purpose of the GPM satellite launched in 2014?

• To observe only snowstorms

• To monitor only the East Coast

• To measure only heavy rain

• To measure a full range of precipitation types

Which colors represent frozen precipitation in the GPM observations?

• Yellow to orange

• Blue to green

• Cyan to purple

• Green to red

In which regions did the snowstorm have a significant impact according to the video?

• California and Nevada

• West Virginia, Virginia, and Maryland

• Texas and Oklahoma

• Florida and Georgia

What advantage does the GPM's broader spectrum of precipitation data provide?

• It ignores snow data

• It only measures heavy rain

• It focuses solely on tropical storms

• It allows for better estimates of water content

What is the role of the GPM core observatory in the international satellite network?

• It is the reference standard for the network

• It operates independently of other satellites

• It serves as a backup satellite

• It only collects data from the United States
