NASA's Earth Now is an application that visualizes recent global climate data from Earth Science satellites, including surface air temperature, carbon dioxide, carbon monoxide, ozone, and water vapor as well as gravity and sea level variations. Data sets are visually described using "false color" maps. Color-coded legends are provided to indicate relative strength or weakness of an environmental condition. The resulting 3D model of the Earth may be rotated by a single finger stroke, and may also be zoomed in or out by pinching 2 fingers. It was developed by the Earth Science Communications and Visualization Technology Applications and Development Teams at NASA's Jet Propulsion Laboratory, with support from NASA Headquarters.

For the Curious
This app is designed to display several data maps gathered via satellite.
These data maps include everything from ozone, carbon dioxide & monoxide levels, to gravity field variations.
Animated data maps can also be displayed, showing changes over time.
All of these maps are rendered in false color tones projected onto a globe. The globe can be rotated but is locked at the poles; you can't turn the whole geoid upside down.
Zooming in and out via multi-touch is very rough, in direct contrast to the silky smooth scrolling iOS and Apple devices are known for. I hope this improves as the app is updated.
Otherwise though, the datasets load very quickly and a details screen can be selected that describes the scale used for the map, the data's importance, and the source of the data.
Improvements I hope to see are:
*Much smoother scrolling, the kind Apple is legendary for
*A higher-resolution globe; the current globe is passable, but pixelated on the Retina Displays, and won't look very good on an iPad
*The ability to control the playback speed of animated data maps, and the ability to scroll through them manually, to see change over time in a specific area of interest, for example
*Additional information on the importance of the displayed data. Many people people (like me) are voracious readers and would love to learn more about the data we're examining
This app is awesome! I find it very useful as a visual to show people the current CO2 atmospheric data when engaging with people about the dangers we face do to a lack of coverage by the media. NASA does incredible things on a shoestring budget! Earth now gives the public a direct link to our satellites most up to date data of earth’s natural systems. Thanks NASA keep up the hard work!
Easy to use & Research based
This delightful App comes from the Jet Propulsion Laboratory, a division of the credible California based science institution, CalTech. In partnership with NASA, this app streams live data from a dozen orbiting satellites to give the curious minded visual representations of temperature, water moisture, carbon dioxide, and more.
Perfectly integrates with many NGSS standards from early elementary through secondary school.
With Family Sharing set up, up to six family members can use this app.
