Synopsis |
| NASA'S HD BLUE MARBLE RESOURCE TAPE (720p/59.94) | G07-HD002 | 7/13/07 | 17:29 | Goddard Television's vision is to produce and communicate knowledge about our study of the Earth and Space; sharing NASA and Goddard Space Flight Center, its missions, programs, discoveries, experts, and facilities with 245 million Americans and other TV viewers around the globe. In line with this vision, Goddard is releasing it's first set of high definition resource tapes, showcasing some of the best visuals we have to offer. This tape is a set of HD visualizations using the "Blue Marble Next Generation" imagery from the Moderate Resolution Imaging Spectroradiometer (MODIS). In it we see beautifully changing seasons and snow cover from a variety of perspectives around the globe.

TAPE CONTENTS: |
| ITEM (1): The Original "Blue Marble" - On December 7, 1972, from a distance of about 45,000 km (28,000 mi), the crew of Apollo 17 took one of the most famous photographs ever made of the Earth. This original Blue Marble inspired later images of the Earth compiled from satellite data.

| ITEM (2): Seasonal Land Cover Change HD Visualizations - The Blue Marble Next Generation dataset provides a monthly, global, cloud-free, true-color picture of the Earth's land cover at a 500-meter spatial resolution. The following visualizations show seasonal variations such as snowfall, spring greening and droughts in a seamless fashion, thereby heightening awareness of changes in the Earth's climate.
a) Global Seasonal Land Cover with Artic Sea Ice -
In this animation, the globe slowly rotates one full turn while seasonal land cover and Arctic sea ice vary through time.
b) Global Tour of Seasonal Land Cover -
This animation shows a global rotation of seasonal changes in land cover. Land cover fades from month to month, and is displayed at a rate of two months per second.
c) Seasonal Land Cover Change over the Eastern United States -
This animation shows how the land cover changes with the seasons as we fly over the Eastern United States, from Florida to Maine.
d) Seasonal Land Cover Change over the Alps -
This animation zooms into Northern Italy and shows seasonal land cover over the Alps and surrounding regions.
e) Seasonal Land Cover Change over Western Asia -
This animation shows land cover changes as we zoom over Western Asia.
f) Seasonal Land Cover Change over Eastern Asia -
This animation shows seasonal land cover changes over Northeastern China and Southeastern Russia, viewed from the vantage point of the Sea of Japan.
g) Seasonal Land Cover Change over the Nile Delta -
This animation shows seasonal land cover change over the Nile delta in 2004.

| ITEM (3): Snow Cover HD Visualizations - The Moderate Resolution Imaging Spectroradiometer (MODIS) provides data in 36 spectral bands, some of which are used in an algorithm to map global snow cover. The following animations show the dynamic behavior of the advance and retreat of continental snow cover.
a) Global Snow Cover from MODIS -
This animation shows the global advance and retreat of continental snow cover for the winter of 2001-02. It concludes with a zoom in to the Sierra Nevada Mountains.
b) Daily Snow and Sea Ice Surface Temperature over the Northern Hemisphere -
This animation shows the daily advance and retreat of snow cover, and sea ice surface temperature over the Northern Hemisphere during the winter of 2002-2003. Snow cover over the tip of South America is also shown during the summer of 2000.
c) Daily Snow and Sea Ice Temperature over the North Pole -
This animation shows the daily advance and retreat of snow cover, and sea ice surface temperature over the North Pole during the winter of 2002-2003.
d) Daily Snow and Sea Ice Temperature over North America -
This animation shows the daily advance and retreat of snow cover, and sea ice surface temperature over North America during the winter of 2002-2003.
e) Daily Snow and Sea Ice Temperature over Europe -
This animation shows the daily advance and retreat of snow cover, and sea ice surface temperature over Europe during the winter of 2002-2003.
f) Daily Snow and Sea Ice Temperature over Asia -
This animation shows the daily advance and retreat of snow cover, and sea ice surface temperature over Asia during the winter of 2002-2003.
