The images in this Envirocast®
Bulletin were taken by the Moderate Resolution Imaging
Spectroradiometer (MODIS)
onboard NASA's
Terra satellite on
January 2, 2007. They show a sunny Mid-Atlantic region in a
mild winter. |
Sunny Mid-Atlantic
The above image was from
the Moderate Resolution Imaging Spectroradiometer (MODIS)
onboard NASA's
Terra
satellite. It shows a sunny Mid-Atlantic region on January 2,
2007. The route of Interstate 95 is easy to follow as a
cement-colored line through eastern Pennsylvania, Maryland, and
Virginia. Several large eastern cities dot the corridor like knots
in a rope: New York City, in the tri-state area; Philadelphia,
along the border of Pennsylvania and New Jersey; Baltimore, in
central Maryland; Washington, D.C., sandwiched between Maryland
and Virginia.

Environmental Impacts:
-
These
MODIS mages show substantial portions of the states of
Pennsylvania, New Jersey, Maryland and Delaware. Most of
the area is free from early-winter snow. The Appalachian Mountains stretches from the lower left to the upper right
of the image.
-
Brown deciduous forests
(without their leaves) extend west from the mountains.
Scattered evergreen forests, colored dark green, lie
between the mountains and the Atlantic coast. Fallow
fields and agricultural areas are light green, while urban
areas appear gray.
Supplementary Material:
NASA's TERRA Satellite:
-
The Terra spacecraft (formally known as
EOS-AM) was successfully launched on Saturday, December
19, 1999 at the Vandenberg Air Force Base (VAFB) in
Lompoc, California. It is flying at an altitude of 705 km
(438 miles) observing the Earth. The life expectancy of
the Terra mission is 6 years. It will be followed in later
years by other EOS spacecraft that take advantage of new
developments in remote sensing technologies. [Terra

showing Terra Orbit]
-
Terra's orbit around the Earth is timed so
that it passes from north to south across the equator in
the morning, and thus it passes over us at the same local
time every day, approximately 10:30-10:45 a.m.
