NASA LANGLEY SCIENTISTS TO PRESENT ATMOSPHERIC SCIENCE
RESEARCH AT AGU
Scientists from NASA Langley Research Center in Hampton, Va.,
will report on new atmospheric science research at the American
Geophysical Union (AGU) fall meeting in San Francisco, Dec. 6 -10,
2002. Highlights of scheduled sessions and papers follow:
Tracing Air Pollution Over the Pacific Ocean
The 2001 Transport and Chemical Evolution over the Pacific
(TRACE-P) airborne field experiment, headed by NASA Langley,
provided an opportunity for scientists to study the composition and
chemical evolution of air as it moves away from Asia and across the
Pacific Ocean. Scientists say the makeup of air originating in Asia
largely corroborates current estimates of Asian emissions, except
for unexpectedly large amounts of carbon monoxide and black carbon
(soot) air pollution. Researchers will explain this result and
others from TRACE-P observations in three sessions called
"Transport and Effects of Anthropogenic Pollutants: TRACE-P." Dr.
Daniel Jacob, TRACE- P mission scientist of Harvard University, and
Dr. James Crawford, TRACE-P deputy mission scientist of NASA
Langley, are the session conveners.
December 6 & 7 at 8:30 a.m.— Moscone Convention Center
(MCC) 102, Sessions A51D and A61D; Poster Session, December 7 at
1:30 p.m.—MCC Hall D, Session A62A
A 3-D View of Air Pollution from Asia
A new software tool is giving scientists an opportunity to
view earth science data like never before. Developed by VRCO Inc.,
the Virtual Global Explorer and Observatory software merges data
collected from airborne and ground-based instruments as well as
satellite observations to create a three-dimensional stereographic
environment. The user can view, navigate and interact with the
data. James Hoell, an SAIC scientist with NASA Langley’s
Atmospheric Sciences Data Center, will present examples from
NASA’s 2001 TRACE-P airborne field experiment. The
three-dimensional visuals will show air pollutants and other
atmospheric constituents originating in Asia and flowing across the
Pacific Ocean.
December 6 at 4:20 p.m.—MCC 135, Session U52A
Science is S’COOL
For over six years, NASA Langley’s Students’ Cloud
Observations On-Line (S’COOL) outreach project has been
helping students study how clouds affect the Earth’s energy
balance. By comparing student observations with cloud measurements
from the Clouds and the Earth’s Radiant Energy System (CERES)
instrument, scientists have gained useful information about the
problem of cloud detection from space. Dr. Lin Chambers will report
on how the S’COOL team continues to evaluate and improve their
international outreach project.
Invited Paper, December 9 at 9:10 a.m.—MCC 270, Session
ED11C
2002 Solar Storms Shine Light on the Earth’s Energy
Balance
An unprecedented series of observations from the
Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics (TIMED)
satellite is allowing scientists to trace the flow of energy from
the Sun to the Earth and determine the balance of energy throughout
the planet’s atmosphere. Dr. Martin Mlynczak will present
results and new images from the Sounding of the Atmosphere using
Broadband Emission Radiometry (SABER) instrument on TIMED that will
show how the solar storms warmed the Earth, changed its energy
balance and impacted the structure of the atmosphere.
Invited Paper, December 9 at 11:20 a.m.—MCC 134, Session
