This set of three videos illustrates how math is used in satellite data analysis. NASA climate scientist Claire Parkinson explains how the Arctic and Antarctic sea ice covers are measured from satellite data and how math is used to determine trends... (View More) in the data. In the first video, she leads viewers from satellite data collection through obtaining a time series of monthly Arctic and Antarctic average sea ice extents for November 1978-December 2016. In the second video, she begins with the time series from the first video, removes the seasonal cycle by calculating yearly averages, and proceeds to calculate the slopes of the lines to get trends in the data, revealing decreasing sea ice coverage in the Arctic and increasing sea ice coverage in the Antarctic. In the third video, she uses a more advanced technique to remove the seasonal cycle and shows that the trends are close to the same, whichever method is used. She emphasizes the power of math and that the techniques shown for satellite sea ice data can also be applied to a wide range of data sets. Note: See Related & Supplemental Resources for the maps and data files (1978-2016) that will allow you to do the calculations shown in the video. These also include data for different regions of the Arctic and Antarctic, enabling learners to do additional calculations beyond those shown in the videos. (View Less)
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)
This short video (02:48) profiles Steve Nesbitt, a scientist affiliated with NASA's Global Precipitation Measurement (GPM) mission. Following a brief description of his career pathway, Nesbitt provides both an overview of the GPM mission as well as... (View More) insights into his work in validating and analyzing the GPM satellite data. (View Less)
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)
Leonard Nimoy narrates this a video about NASA's Dawn mission to the asteroids Vesta and Ceres. Learners will follow the mission from paper to launch pad to asteroid belt and beyond. The video features the planning, instrumentation and technological... (View More) challenges of this unique mission. Note: This video was produced pre-launch in 2007.
