As
we look at Earth from the vantage point of outer space, we can't but help notice
how important water is to Earth's surface. Three quarters of our planet is covered
with liquid and frozen water. The land surface is shaped by water's movements.
Living things need water for survival. Water exists as vapor in the atmosphere
and is the stuff of clouds. As a renewable resource, water transforms through
three states of matter, solid, liquid, and gas as it cycles from the oceans
to the atmosphere, to the land, and back to the oceans. Water and its effects
are the dominant features Space Shuttle astronauts see from space. Water is
a powerful force of change.

This
image was acquired from the GOES-8 Imager by the Laboratory
for Atmosphere's, at NASA's Goddard Space Flight Center. It
was taken on September 2, 1994, using two channels of the
Imager to produce a "natural color" effect.

This
illustration as a part of NASA's program of Earth-science
research, shows the world's cloud cover pattern on October
15, 1983, assembled from weather satellite images made at
infrared wavelengths. Although a single image of Earth's cloud
cover had been assembled from multiple satellite images before,
this picture is the first time that an image had been collected
for such a small time period, in this case only about one
hour. This kind of information enables scientists to study
global cloudiness to improve our understanding of how clouds
affect climate.

This
illustration of Earth's sea surface temperature is part of NASA Goddard
Space Flight Center's program of Earth-science research. It was obtained
from two weeks of infrared observations by the Advanced Very High Resolution
Radiometer (AVHRR), an instrument on board NOAA-7 during July 1984.
This
study is part of NASA's multiyear global research program
called Mission to Planet Earth.

This
image shows March monthly average ozone levels during a 14-year period
taken from NASA's Total Ozone Mapping Spectrometer (TOMS) aboard the Nimbus-7
satellite. Shown here are the first four years, 1979-1982, and the last
four years, 1990-1993 of TOMS imaging .
To
ensure that ozone data will be available through the next decade, NASA
will continue the TOMS program; using U.S. and foreign launches. The Japanese
Advanced Earth Observations Satellite (ADEOS) will carry a fourth TOMS
into orbit when it launches in 1996, and a fifth TOMS Instrument is being
assembled for flight in 1998 on an undetermined satellite. The TOMS program
is managed by NASA's Goddard Space Flight Center, for the Office of Mission
to Planet Earth.

quicktime movie from TOMS on

This
image shows October monthly average ozone levels during a 14-year period,
1979-1992. The ozone measurements were taken by NASA's Total Ozone Mapping
Spectrometer (TOMS) aboard the Nimbus-7 satellite, managed by the Goddard
Space Flight Center.
The
color scale on the right side of this image shows the total ozone values
for the 14-years measured. The ozone levels are indicated by the colors
green/light blue, low levels by the color dark blue/purple and high levels
by the red colors. The Antarctic "ozone hole" is indicated by
the low values (dark purple colors). This contrasts with the relatively
higher ozone values over Antarctica in earlier years (1979-1982), when
the hole is virtually nonexistent (blue green/green colors).

quicktime movie from TOMS on 10/01/92-10/31/92.

This
computer generated illustration of Earth is part of NASA Goddard Space
Flight Center's program of Earth-science research. This view, generated
from orbiting and ground-based instruments, shows a computer-generated
topographic image of the continents with the vegetation of Earth superimposed
over it.
The
vegetation covering the continents was recorded by the Advanced Very High
Resolution Radiometer (AVHRR) aboard the NOAA-7, NOAA-9, and NOAA-11 satellites.
This
study is part of NASA's multiyear global research program
called Mission to Planet Earth. It will use ground-based,
airborne, and space-based instruments to study Earth as a
complete environmental system.

These
four color-coded, digitized maps for December 1978, 1981, 1985, and 1986
show the floating ice coverage of the Arctic Ocean and the surrounding
sea. The amount of sea-ice coverage at a given location is depicted by
the color scale to the right of the maps ranging from 0% of the sea covered
in ice to 100% ice coverage. This is the computer representation of the
monthly averages of sea ice seen from space by the Scanning Multichannel
Microwave Radiometer (SMMR) aboard NASA's Nimbus-7 Earth-orbiting satellite,
launched October 24, 1978.
Scientists
use the data contained in maps like these for clues about
global warming. The Nimbus-7 satellite is managed by NASA's
Goddard Space Flight Center.

Space
radar images of Earth from the Shuttle
- Spaceborne
Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) is a joint U.S.-German-Italian
project that uses a highly sophisticated imaging radar to capture images of
Earth that are useful to scientists across a great range of disciplines. It
was flown on STS-68 and STS-59.
