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.

South pole covered

What is the big deal with this people?

South pole is covered with a black circle, useless

For the Curious

Fabuloso Fabio

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


Nice way to expose non-scientists to some scientific data


I too am looking forward to additional data layers that I know NASA has (e.g. SST), but I think this is a great app. I wish there was an iPad version, but this is a great start. For those who aren't sure what they are looking at, just press the Details button and it will tell you a bit about what the data is and how it is measured. For example, reading the details about the GRACE data (gravity field) is very interesting. I too would have thought the changes were slower, but there are some pretty significant changes in the past couple of years.

Thanks JPL.

(iPad version, please!)
