NASA PRESENTATIONS AT INTERNATIONAL SYMPOSIUM
NASA scientists will present a variety of Earth science
topics at the International Geoscience and Remote Sensing
Symposium (IGARSS) at the Centre de Congres Pierre Baudis,
Toulouse, France, July 21-25, 2003.
Presentations of particular interest (all times local):
REMOTE SENSING OF EVAPOTRANSPIRATION FOR PRECISION-FARMING
APPLICATIONS
John Norman, a NASA funded scientist, from the University of
Wisconsin-Madison will discuss how researchers developed a
two-tier method for estimating evaporation from plants and
soil. His talk describes the procedures for conducting
observations and presents validation data demonstrating the
usefulness of this method. July 21, 2:20 p.m., Salle
Guillaumet One, Congres Centre, Level 4.
A QUARTER CENTURY OF SPACE RADAR GEOLOGY: FROM SEASAT TO THE
SHUTTLE RADAR TOPOGRAPHY MISSION
NASA Jet Propulsion Laboratory (JPL) Director Charles
Elachi, a leading expert on imaging radar and other remote-
sensing technologies, travels back in time to highlight the
many space radar missions and instruments involving the
agency and how they relate to our knowledge and
understanding of Earth yesterday, today and tomorrow. July
21, 4:40 p.m., Amphitheatre Verdi, Atria Hotel.
THE DECADAL TROPICAL MEAN RADIATION DATA AND THE IRIS
HYPOTHESIS
As the climate changes, will the Earth's 'Iris' counteract
predictions of global warming and help cool the planet? Bing
Lin from NASA's Langley Research Center, Hampton, Va., will
present the newest results that cast doubt on the global
cooling theory called the Iris Hypothesis. This presentation
is in the Earth Radiation Budget session on July 22, 8:20
a.m. to 12:20 p.m., Salon Caravelle 1, Congres Centre, Level
1.
CLIMATIC TRIGGER EVENTS FOR EBOLA HEMORRHAGIC FEVER
OUTBREAKS: "THE FOREST, THE FLY, AND THE VIRUS"
Compton Tucker, Goddard Space Flight Center (GSFC),
Greenbelt, Md., will discuss spatially continuous satellite
data on precipitation within tropical Africa. He will show
the majority of documented Ebola hemorrhagic fever outbreaks
were closely associated with sharply drier conditions at the
end of the rainy season followed immediately by a sharply
wetter period as the dry season started. July 22, 2:40 p.m.,
Auditorium de Saint Exupery, Congres Centre, Level 4.
MULTI-YEAR MODIS OBSERVATION OF GLOBAL AEROSOLS FROM EOS
TERRA/AQUA SATELLITES
Lorraine Remer, GSFC, discusses how the MODIS instrument has
been collecting data on global aerosols from the Terra
satellite for three years. These data give a three-year time
series of the global state of the Earth's aerosols (dust,
sea salt, smoke, particles). The data is the beginning of
global aerosol climatology, and gives insight into the
inter-annual variability of these particles, vital to
building global climate models that attempt to incorporate
the role of aerosols into estimates of global change. July
23, 9:20 a.m., Auditorium de Saint Exupery, Congres Centre,
Level 4.
QUIKSCAT WIND RETRIEVALS FOR TROPICAL CYCLONES
JPL project scientist Timothy Liu will discuss new methods
of retrieving ocean surface wind measurements under the
strong winds and rainy conditions of a tropical cyclone
using the Seawinds scatterometer instrument aboard NASA's
Quikscat satellite. July 24, 9 a.m., Ampitheatre Verdi,
Atria Hotel.
VOLCANIC HAZARDS MONITORING WITH ASTER DATA
A graphic presentation by JPL research scientists Michael
Abrams and David Pieri features detailed images from the
Advanced Spaceborne Thermal Emission and Reflection
Radiometer, an imaging instrument on NASA's Earth-orbiting
Terra satellite, that helps monitor and predict volcanic
eruptions. July 25, 8:20 a.m. to 12:20 p.m., Salon Caravelle
1, Congres Centre (A corresponding presentation by Abrams is
on July 24, 11:20 a.m., Salle Spot in the Congres Centre).
