- The second spinoff video for the Science on a Sphere film "Water Falls." This video looks at the uses and advantages of remote sensing.This website, presented by NASA’s Global Precipitation Measurement (GPM) mission, provides students and educators with resources to learn about Earth’s water cycle, weather and climate, and the technology and societal applications of studying them.
- Salinity plays a major role in how ocean waters circulate around the globe. Salinity changes can create ocean circulation changes that, in turn, may impact regional and global climates. The extent to which salinity impacts our global ocean circulation is still relatively unknown, but NASA's new Aquarius mission will help advance that understanding by painting a global picture of our planet's salty waters.
- Aquarius is a collaboration between NASA and the Space Agency of Argentina to measure global sea surface salinity (the amount of dissolved salts in water). Measuring salinity can help us better understand the water cycle and can also lead to improved climate models. The visualizations show the complete observations of sea surface salinity taken during the life span (2011 through May 2015) of the Aquarius spacecraft. In these visualizations, sea surface salinity is shown ranging from 30 to 40 PSU (from blue to green to red) on a flat map using simple cartesian and extended Molleide projections. The visualizations were generated based on version 4.0 of the Aquarius data products.
- The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. These two regions don't mix except in certain special areas. The ocean currents, the movement of the ocean in the surface layer, are driven mostly by the wind. In certain areas near the polar oceans, the colder surface water also gets saltier due to evaporation or sea ice formation. In these regions, the surface water becomes dense enough to sink to the ocean depths. This pumping of surface water into the deep ocean forces the deep water to move horizontally until it can find an area on the world where it can rise back to the surface and close the current loop. The actual flows in this model are based on current theories of the thermohaline circulation rather than actual data. The thermohaline circulation is a very slow moving current that can be difficult to distinguish from general ocean circulation. Therefore, it is difficult to measure or simulate.
- This visualization shows sea surface current flows. The flows are colored by corresponding sea surface temperature data. This visualization is rendered for display on very high resolution devices like hyperwalls or for print media.<p><p>This visualization was produced using model output from the joint MIT/JPL project entitled <a href="http://ecco2.org/">Estimating the Circulation and Climate of the Ocean, Phase II (ECCO2)</a>. ECCO2 uses the MIT general circulation model (MITgcm) to synthesize satellite and in-situ data of the global ocean and sea-ice at resolutions that begin to resolve ocean eddies and other narrow current systems, which transport heat and carbon in the oceans. The ECCO2 model simulates ocean flows at all depths, but only surface flows are used in this visualization.
- El Niño is characterized by unusually warm ocean temperatures in the eastern equatorial Pacific. Sea surface temperature is the temperature of the top millimeter of the ocean's surface. A sea surface temperature anomaly (SSTA) represents how different the ocean temperature, at a particular location and time, is from the normal (or average) temperature for that place and time. <p> These maps, showing sea surface temperature and sea surface temperature anomalies, reveal the progression of the strong 2015-16 El Nino event from January 1, 2015 to January 2, 2016. The sea surface temperature data are seven-day averages calculated using daily thermal data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. Missing data have been filled with monthly-average data. The sea surface temperature anomaly data are seven-day averages calculated using the 5-kilometer Coral Reef Watch product produced by the National Oceanic and Atmospheric Administration. The data are based on observations from geostationary and polar-orbiting satellites.
- The Precipitation Education website, presented by NASA’s Global Precipitation Measurement (GPM) mission, provides students and educators with resources to learn about Earth’s water cycle, weather and climate, and the technology and societal applications of studying them.

- On December 5, 2014 (1032UTC) the Global Precipitation Measurement (GPM) mission's Core Observatory flew over Typhoon Hagupit as it headed towards the Philippines. A few hours later at 1500 UTC (10 a.m. EST), Super Typhoon Hagupit's maximum sustained winds were near 130 knots (149.6 mph/241 kph), down from 150 knots (172 mph/277.8 kph). Typhoon-force winds extend out 40 nautical miles (46 miles/74 km) from the center, while tropical-storm-force winds extend out to 120 miles (138 miles/222 km). The GPM Core Observatory carries two instruments that show the location and intensity of rain and snow, which defines a crucial part of the storm structure – and how it will behave. The GPM Microwave Imager sees through the tops of clouds to observe how much and where precipitation occurs, and the Dual-frequency Precipitation Radar observes precise details of precipitation in 3-dimensions. For forecasters, GPM's microwave and radar data are part of the toolbox of satellite data, including other low Earth orbit and geostationary satellites, that they use to monitor tropical cyclones and hurricanes. The addition of GPM data to the current suite of satellite data is timely. Its predecessor precipitation satellite, the Tropical Rainfall Measuring Mission, is 18 years into what was originally a three-year mission. GPM's new high-resolution microwave imager data and the unique radar data ensure that forecasters and modelers won't have a gap in coverage. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency. All GPM data products can be found at NASA Goddard's Precipitation Processing Center website <a href="http://pps.gsfc.nasa.gov/">http://pps.gsfc.nasa.gov/</a>.
- The ten satellites in the Global Precipitation Measurement Constellation provide unprecedented information about the rain and snow across the entire Earth. This visualization shows the constellation in action, taking precipitation measurements underneath the satellite orbits. As time progresses and the Earth's surface is covered with measurements, the structure of the Earth's preciptation becomes clearer, from the constant rainfall patterns along the Equator to the storm fronts in the mid-latitudes. The dynamic nature of the precipitation is revealed as time speeds up and the satellite data swaths merge into a continuous animation of changing rain and snowfall. Finally, the video fades into an animation of IMERG, the newly available data set of global precipitation every thirty minutes that is derived from this satellite data.
- The global IMERG precipitation dataset provides rainfall rates for the entire world every thirty minutes. This remarkable dataset is created by combining precipitation measurements from 10 international satellites: GPM, TRMM, GCOM-W1, NOAA-18, NOAA-19, DMSP F-16, DMSP F-17, DMSP F-18, Metop-A, and Metop-B Although the process to create the combined dataset is intensive, the Global Precipitation Measurement team creates a preliminary, near real-time data set of precipitation within about a day of data acquisition. The animation on this page shows the most recent week or so of that preliminary data.
- his series of ten lessons has been developed to teach students about local and global water issues. They are based on NASA’s Global Precipitation Measurement (GPM) Mission. The activities are done largely outdoors and include scientific data collection and analysis and integrate technology. Many of the lessons involve data collected based on protocols from the GLOBE Program. Each lesson is designed to take one hour; the lessons build on each other, but can also be used independently. Each lesson topic includes a lesson plan, PowerPoint presentation, student capture sheet and capture sheet answer guide.
- This interactive adventure uses a Landsat mosaic of Arizona as the interface. Students need to interpret satellite imagery to receive clues to Echo the Bat's location. As students find Echo, additional content about remote sensing and biodiversity is introduced.
- This 12-page educational comic book introduces readers to the Global Precipitation Measurement (GPM) mission. Using the Japanese anime art style, the comic book explains the satellite technology and the mission goals and applications. Supplemental materials to support the story include an overview of the GPM mission, a description of the satellite and its instruments, examples of the data it collects, descriptions of some of the constellation partners, and a glossary of science terms used in the comic. Links are provided to additional related resources, including a template for learners to create their own comic. The Japanese anime/manga style of art was chosen because the GPM mission is a collaboration between NASA and JAXA, the Japan Aerospace Exploration Agency.
- Information about how various NASA missions use the electromagnetic spectrum to discover information about the natural world.
- This joint NASA/USGS program provides the longest continuous space-based record of Earth’s land in existence. Every day, Landsat satellites provide essential information to help land managers and policy makers make wise decisions about our resources and our environment.
- This activity allows participants to build a paper model of the GPM Core Observatory and learn about the technology the satellite uses to measure precipitation from space. Directions explain how to cut, fold and glue the individual pieces together to make the model. The accompanying information sheet has details about the systems in the satellite including the Dual-frequency Precipitation Radar (DPR), the GPM Microwave Imager (GMI), the High Gain Antenna, avionics and star trackers, propulsion system and solar array, as well as a math connection and additional engineering challenges.
- This site features information about constructing a LEGO model of the Global Precipitation Measurement (GPM) Mission Core Observatory. Two options for building the GPM model are provided: students can construct a 3D model on the LEGO website or build an actual LEGO model of the satellite (information is provided for purchasing individual parts or for purchasing a pre-packaged kit). In addition to learning about the primary components of the GPM satellite, students will also learn facts about the mission, its technology and instrumentation.AAAS Benchmarks: 3A/M2
