NASA' MTPE/EOS Exhibit Backdrop Image Design.

And Interactive Website for Design Discussion

NASA is designing on a new conference exhibit backdrop for the Mission to Planet Earth/Earth Observing System (MPTE/EOS) Program. The backdrop is to be, 20x10 feet in size, with back lighting for brightness and visual appeal. Click on the top-left image for a closer view of the draft design. The centerpiece of the backdrop design is a large synthetic three-dimensional image of the Earth while the peripheral images depict the world as seen by different EOS-like sensors.

The latest version of the of the synthetic 3D Earth image is shown below for your consideration and comments. Click on the caption the view the medium size (600x600) or the large (4000x4000) version of the image.

Tentative Figure Caption: The Earth image is synthesized from four remotely sensed data layers: visible light reflection over land (SeaWiFS), fires over land (AVHRR), aerosol over the oceans (AVHRR) and IR cloud image from four geostationary satellites. The large aerosol plume over the Atlantic is from biomass burning and wind blown dust emitted over Africa. Such data fusion from multiple sensors, along with surface-based observations and modeling studies address the key scientific challenge of MTPE: how do the Earth's land, water, air, and life interact to produce the environment in which we live? (Synthetic image by R.B. Husar, Washington U.; land layer by the SeaWiFS Project, fire maps from ESA, aerosol layer from NOAA-NESDIS and cloud layer by SSEC, U. Wisconsin.

Data Sources for the Synthetic Earth Image

All the data used in the synthetic earth image were found through the Web and were freely accessible through the respective Web servers. The land image layer was generated by NASA-GSFC SeaWiFS Project. It is a true color (blue-green-red composite) of the word for cloud-free conditions, September 18-October 3, 1997. The fire maps were obtained from the European Space Agency (ESA) Fire Atlas for January and July. Each red dot represents a fire location detected by the ATSR sensor. The oceanic aerosol layer is based on NOAA-NESDIS AVHRR aerosol data product for the winter season, December, January and February of 1990 and 1991, published in Journal of Geophysical Research (1997), 16889-16909. The cloud layer is a composite of IR images from four geostationary satellites, GOES 8, GOES 9, METEOSAT and GMS 5, for Sep. 17,1997 produced by the U. Wisconsin, SSEC KidSat Project.

Final Backdrop Implementation

The new conference exhibit backdrop for the Earth Science Enterprise Program is now in use by NASA at various scientific meetings. It is 20x10 feet in size, with back lighting. Here is a picture of the backdrop designer, Winnie Humberson at the December 98 San Francisco AGU meeting exhibition and that of the proud implementor of the center globe image, Rudolf Husar. Also, in December 1998 NASA has printed 40,000 copies of the ESE poster for distribution to the public.


About this Website

This 'lightweight' website was set up to seek input from the 'community' regarding the design of the centerpiece globe image, including (1) the message that is to be transmitted (the goal), (2) the content (data) that will convey the desired message and (3) the rendering for an esthetically pleasing presentation.

An additional purpose of this interactive website is to gain more experience in the use of the Web as a medium for communication and consensus building. Members of the community have been approached by e-mail to comment on the image design and requested to submit their comments 'publicly' through feedback forms on these pages. If necessary, messages can be kept private through direct e-mail.

In order to participate in the discussion:

  1. Go to the People's page to register, a necessary step before submission of comments.
  2. On any forum page, submit a new comment or respond to an exiting comment.
  3. Your contribution will appear automatically on the selected page.
  4. Alternatively, send your comments through e-mail to R. Husar and we will post it for you.
