NASA PRESENTS AT THE 2007 AMERICAN GEOPHYSICAL UNION MEETING
WASHINGTON - NASA researchers will present findings on a variety of
Earth and space science topics at the 2007 Joint Assembly Meeting of
the American Geophysical Union. The meeting runs May 22-25 at the
Acapulco Convention Center, Acapulco, Mexico. Sessions are open to
registered news media.
Following are noteworthy NASA presentations, in chronological order
(all times CDT):
Using Time Series of Impervious Cover and Tree Cover to Study Urban
Dynamics in the Upper Delaware River Basin
TIME: Tuesday, May 22, 11:40 a.m., Room ACC 04
SESSION: H22B-06
Scientists using satellite data to examine recent urban growth
patterns in the Upper Delaware River Basin will discuss results that
are helping to simulate future urban growth, an important tool for
urban planning in the watershed.
Development, Implementation and Evaluation of a Real-Time Ocean
Forecasting System off the California Coast
TIME: Tuesday, May 22, 2:30 p.m., Room ACC 07
SESSION: OS23H-03
Scientists will discuss ongoing work to develop and implement a
real-time ocean forecast system based on the Regional Ocean Modeling
System off the coast of California.
Intercontinental Transport of Aerosols: Implication for Regional Air
Quality
TIME: Tuesday, May 22, 4:50 p.m., Room ACC 02
SESSION: A24A-03
Researchers will discuss findings from a NASA computer model that
estimates the hemispheric impact of anthropogenic sulfate aerosols
and dust from major air pollution sources.
Mars News from Ground Level and From Orbit
TIME: Wednesday, May 23, 10:20 a.m. and 11:20 a.m., Room ACC 13
SESSION: P32A and P32A-05
NASA's Mars Reconnaissance Orbiter mission science team members will
present initial results from the orbiter's composition-mapping
spectrometer and its high-resolution camera, including information
about layers of minerals that form under wet conditions. NASA's Mars
Exploration Rovers science team will discuss past environmental
conditions from exposed layers of bedrock viewed by Opportunity at
Victoria Crater and from soil and rocks examined by Spirit in Gusev
Crater.
Insights into Mega-City Ozone Pollution from the INTEX Ozonesonde
Network Study, 2004 and 2006
TIME: Wednesday, May 23, 11:35 a.m., Room ACC 02
SESSION: A32A-06
NASA-led field campaigns have observed highly variable levels of ozone
throughout the lower atmosphere. Researchers will show how this
variability is due to complex interactions between weather and
chemistry and natural and human-made contributions to ozone.
Linking Aerosol Source Activities to Present and Future Climate
Effects
TIME: Thursday, May 24, 5:00 p.m., Room ACC 03
SESSION: A44A-03
NASA's Dorothy Koch discusses a global model to connect specific
aerosol emission sectors (transport, power, industry, residential,
biomass burning) to climate effects for recent and future special
reports on emission scenarios from the Intergovernmental Panel on
Climate Change.
A Trend in the Northward Transport of Saharan Dust and its Links to
the Trend in North Atlantic Tropical Cyclone Energy
TIME: Friday, May 25, 12:05 p.m., Room ACC 02
SESSION: A52A-08
NASA computer simulations show how a decline in Saharan dust during
the past two decades, combined with warming sea surface temperatures
related to the Atlantic Multidecadal Oscillation, may be working in
concert to increase tropical cyclone formation in the Atlantic.
The Role of Irrigation in North American Hydroclimates
TIME: Friday, May 25, 3:15 p.m., Room ACC 05
SESSION: H53F-06
Researchers will discuss new insights in improving weather and climate
predictions by including land irrigation in operational prediction
systems, using advanced computer simulations.
Drought, Wetland and Flood Monitoring with Satellite Scatterometer
TIME: Friday, May 25, 3:20 p.m., Room ACC 01
SESSION: U53B-05
NASA's QuikScat satellite detects surface soil moisture changes and
corresponding changes in vegetation. Scientists will show how
QuikScat data are being used to monitor droughts, wetlands and
floods.
Mechanistic Response of Terrestrial Plant Productivity and Surface
Energy Budget to Routine Aerosol Loading over the Eastern United
States
TIME: Friday, May 25, 4:35 p.m., Room ACC 02
SESSION: A54B-02
Aerosols created from air pollution and other human-made and natural
sources can act to cool or warm Earth. Researchers will present
findings suggesting that moderate air pollution may help reduce
greenhouse warming by trapping more carbon dioxide in forests.
