Title: Earth Today


1
Earth Today
A Powerful and Exciting Exhibit for Learning
About Earth and Space
2
Earth Today
Earth Today (ET) is an exhibit that displays
near-real-time earth and space data. Narration
can also be frequently updated by scientists to
explain near-real-time events. Narration is both
screen text and a voice over. New data sets can
be easily incorporated.

How Does Earth Today Work?
  • ET operates by ingesting global data sets from
    NASA, NOAA, and USGS into our central server.
  • The central server pre-processes the data into
    images and stores them for download onto ET
    Display Systems.
  • ET Display Systems automatically download new
    images every day from the central server through
    a high-speed, internet connection.

Museum Display Server uploads processed images
and text from central server daily.

Earth Today Narration Update
  • Scientists who participate in Earth Today program
    can
  • View ET on their computers and use it in
    presentations.
  • Modify the text through a secure website.
  • Modified text is then included in next update to
    Display Servers.

Scientists
Museums
  • ET is a robust, cost effective, easy to maintain
    display that are content-rich and always current
    and compelling.
  • The ET display systems are delivered and set up
    as complete, operational systems, requiring no
    customer technical expertise.
  • Museums need only to provide power and a
    high-speed internet connection.
  • - Scientists have their data shown wherever ET is
    displayed.
  • Scientists are able to view ET on their PC and
    update their text and voice through a secure
    website.
  • Scientists can contribute to the Notable
    Events menu on the interactive Kiosk.
  • - ET provides unprecedented outreach exposure.
  • Scientists play an integral role in the
    development of science-driven movies in the ET
    Learning Center.
  • Movies are available in formats ranging from HD
    to QT.

Earth Today Passive Display
The Passive system consists of a computer, a
projector or monitor, and a high-speed internet
connection. Daily updates of earth and space
observations and narration, make ET the most
powerful and exciting tool available for viewing
dynamic planets. The system is designed to
easily allow our scientists to update the voice
over and screen text through a secure website in
order to draw attention to significant events.

Earth Today Interactive Kiosk
The ET Interactive Kiosk features a display
screen and a touch screen with selection tools
that control the display. The ET Interactive
Kiosk, has two sections, the Interactive Center
and the Learning Center.

Earth Today Kiosk Configurations
The Interactive Center Using a touch screen,
viewers are able to manipulate the display.
Viewers can choose a data set, the dates viewed,
or choose from thenotable events menu. Viewers
control the global orientation and rotation,
compare archived data to current data, or zoom
into a particular region. Viewers can also
overlay a second data set and adjust the
transparency. The Learning Center The
Learning Center consists of a number of short,
educational movies that provide information about
the ET data sets and the science behind them.
Additional movies are added through the high
speed internet connection.
9
Earth Today Interactive Center
The Interactive Center has three interactive
panels. The first panel allows viewers to
choose a data set. Viewers can select an
optional second data set to overlay the first.
The degree of transparency of the second data
set is adjustable.

The second panel allows the viewer to choose the
time period. The latest 30 days, a continuous
sequence, the same period over multiple years,
or select a preset from the Notable Event menu.
11

The third panel allows viewers to adjust the
rotation speed or stop the globe, change the
speed of data advancement, adjust the globe
orientation, or zoom into a region of interest.
12
Earth Today Learning Center
The Learning Center contains a number of short,
educational movies about the ET data sets and the
science behind them. Each movie uses a
combination of data, graphs, conceptual
animations, and videos to craft a complete story.
The Learning Center has two sections Mission
specific movies and Theme-based movies.
Mission Specific Movies What is the Satellite
and instrument sensors? What part of the IR
spectrum is observed? What are the science
questions? What are the science results?
How is this relevant and why should I care?
Other interesting, relevant science stories.
As additional movies are developed, they are
automatically added to the ET server.

Display Screens
  • Theme Movies
  • Explain earth and space science themes that cut
    across several ET data sources, such as Climate
    Change, and the Carbon Cycle.

How Do Scientists Update Their Text?
Scientists can log onto a secured website to
update the text that appears on the screen and
the voice over. They can play a preview the
text-to-speech on the website before submitting
the updates to the Earth Today ingest server.

Earth Today
  • Earth Today (ET) is an exhibit that displays
    near-real-time earth science data.
  • The data is displayed as a rotating global
    image with accompanying narration and screen
    text.
  • ET operates by downloading global data sets
    from operational servers into a central server
    which pre-processes the data into images and
    stores them for museum display systems.
  • The ET museum display system automatically
    downloads the images from the ET server through a
    broadband connection, updating the museum display
    several times a day.
  • The capability exists to add any number of
    global data sets to the system.

To operate this exhibit, museums need a Macintosh
G5, a projection device (such as a projector or
monitor), and a broadband connection. ET is
presently displayed at the Smithsonian Air
Space Museum, the Maryland Science center, and
the NASA GSFC visitors center.

Earth Today
  • Two new ET developments underway
  • The Learning Center.
  • The Website will contain movies, fac sheets, and
    links.

The initial code was developed at NASA GSFC. The
continuing code development is by a private
company, Animated-Earth LLC. For more

Ideas for SOS animations and overlays
18
Spurr Eruptioneruption flight tracks, see QT
19
This is a poster, but I can imagine comparing
human events like this compared to natural events
with photos on SOS
20
Hadley CycleI can imagine overlays like trade
winds and the Hadley Cycle on SOS. See the QT
on this disk. The rotation of the arrows could
be adapted to moving arrow overlays for SOS.
21
Global ConveyorIt would be easy for me to make a
conveyor overlay for SOS. This illustration has
more detail than the following one.
22
Ocean ConveyorIt would be easy for me to make a
conveyor overlay like this for SOS. This
illustration has less detail than the previous
one.
23
MODIS LayersThis is a concept draft, where the
discussion of the IR spectrum and the
significance of the signature influences what
bands we choose to look at to emphasize different
results with the data. See the QT on this disk.
24
CO Measured by MOPITTThis is a data animation of
CO, which could be compared to model data. You
can really tell who uses energy or biomass
burning. The time bar could be placed along the
equator or on a side screen. See the QT on this
disk.
25
TRMM Swath movieThis is another animation of a
satellite making measurements. There are only
two passes to show how the swaths overlap. See
the QT on this disk.
26
SARThis movie was designed for another purpose,
but I can imagine this technique as a way of
drilling into a local region on SOS, placing the
drilled-down frames along the center third of the
sphere. See the movie on this disk.
