RELEASE: 98-195
NASA HELPS "HOT" CITIES COOL DOWN
Environmental planning for the 2002 Olympic games, strategies
to reduce ozone levels, focused tree-planting programs and
identification of cool roofs are early spinoffs from a NASA urban
study just concluding in three U.S. cities.
Researchers from NASA's Marshall Space Flight Center,
Huntsville, AL, flew a thermal camera mounted on a NASA aircraft
over Baton Rouge, LA; Sacramento, CA; and Salt Lake City, UT. The
thermal camera took each city's temperature and produced an image
that pinpoints the cities' "hot spots."
The researchers are using the images to study which city
surfaces contribute to bubble-like accumulations of hot air,
called urban heat islands. The bubbles of hot air develop over
cities as naturally vegetated surfaces are replaced with asphalt,
concrete, rooftops and other man-made materials.
"One thing's for sure, the three cities we've looked at were
hot," said the study's lead investigator, Dr. Jeff Luvall of
Marshall's Global Hydrology and Climate Center. "They can use a
lot of trees and reflective rooftops."
Salt Lake City is using the early results to help plan sites
for the 2002 Olympic Games and develop strategies to reduce
ground-level ozone concentrations in the Salt Lake City valley.
Though at high altitudes ozone protects the Earth from ultraviolet
rays, at ground level it is a powerful and dangerous respiratory
irritant found in cities during the summer's hottest months.
In Sacramento and Baton Rouge, city planners and tree-
planting organizations are using the study to focus their tree-
planting programs. "We are helping the citiesincorporate the
study into their urban planning," said Maury Estes, an urban
planner on the science team at Marshall. "By choosing strategic
areas in which to plant trees and by encouraging the use of light-
colored, reflective building material, we think that the cities
can be cooled."
The science team will continue to analyze the thermal heat
information and work with the cities to incorporate future results
into the cities' plans. The team plans to disseminate its
findings nationally so other cities can incorporate what the team
has learned into their long-range growth plans.
This study is supported by NASA's Earth Science enterprise.
The enterprise is responsible for a long-term, coordinated
research effort to study the total Earth system and the effects of
natural and human-induced changes on the global environment. This
project also is aimed at the enterprise's efforts to make more
near-term economic and societal benefits of Earth science research
and data products available to the broader community of public and
private users.
Working on the study are researchers from Marshall; the
Environmental Protection Agency, Washington, DC; the Department of
Energy, Washington, DC; Lawrence Berkeley National Laboratory,
Berkeley, CA; Baton Rouge Green, LA; the Sacramento Tree
Foundation, CA; Tree Utah, Salt Lake City; and the Utah State
Energy Services Department, Salt Lake City.
