This short video (2:01) uses an engaging approach to emphasize the importance of tracking and studying precipitation. The video cast explains how the Global Precipitation Measurement (GPM) mission will use a constellation of satellites to achieve... (View More) global coverage, thereby providing scientists with accurate precipitation data from around the world. In addition to the video, the site contains supplemental text which provides background information on the GPM mission. (View Less)

Participants respond to 10 multiple-choice questions related to glaciers and ice-caps. Immediate feedback, explanations and a final score are provided.

This short video (4:06) provides an overview of the Global Precipitation Measurement (GPM) mission. This mission will set a new standard for precipitation measurements from space by joining forces with countries around the world, to provide... (View More) precipitation data from nine different satellites, creating the GPM Constellation. NASA has partnered with the Japan Aerospace and Exploration Agency (JAXA), space agencies in France and India, and the operators of meteorological satellites in Europe and the United States to make this multi-nation mission possible.

This short video (4:44) helps audiences understand and appreciate the importance of measuring precipitation globally. The role of the Global Precipitation Measurement (GPM) mission to better understand, model and predict where and when too much... (View More) rainfall will occur (resulting in floods and landslides) and where too little rain will fall (resulting in droughts) is examined. (View Less)

This 5-minute animation portrays fluctuations in the cryosphere through observations collected from a variety of satellite-based sensors. The cryosphere consists of those parts of the Earth's surface where water is found in solid form, including... (View More) areas of snow, sea ice, glaciers, permafrost, ice sheets, and icebergs. In these regions, surface temperatures remain below freezing for a portion of each year. (View Less)
