Aging weather
satellite fleet at risk

MIAMI - Scientists soon will lose access to crucial information
that helps them better understand and predict everything from
hurricanes and earthquakes to global warming and environmental
decay, according to a candid and sobering report by prestigious
experts.
As wide gaps develop in the ability of scientists to analyze
natural phenomena, Floridians - particularly vulnerable to
hurricanes, rising sea levels and environmental changes affecting
fisheries and farmers - could be especially affected.
"It's a train wreck," said Otis Brown, dean of the University of
Miami's Rosenstiel School of Marine and Atmospheric Science and a
member of the National Academy of Science's panel that issued the
report earlier this month.
"When you hope for the best, this is about the worst you could
imagine in terms of things going awry," he said.
Among the reasons for this reversal of scientific fortunes: sharp
budget cuts, ill-advised technological compromises, and a botched
partnership between the National Aeronautics and Space
Administration and the National Oceanic and Atmospheric
Administration, according to the report.
And the setbacks come at an inopportune time.
NOAA recently reported that last year was the warmest on record
in the United States, and a major study scheduled for release Friday
by an international group of scientists is expected to amplify the
developing crisis of global warming.
Scientist Stephen Hawking and several colleagues recently said
climate change posed a threat nearly equal to that of nuclear
proliferation.
To date, no one has challenged the panel's conclusions, which
were released Jan. 15. NOAA and NASA said they were studying the
436-page report. A congressional committee vowed to apply "vigorous
oversight" to the situation.
Among the highlights - or possibly lowlights - of the report by
scores of experts working with the academy, which is chartered by
Congress and advises the federal government on scientific
matters:
_By 2010, the number of operating sensors and instruments on
NASA's aging fleet of weather and other global-monitoring satellites
will decrease 40 percent, and replacement sensors are behind
schedule, over budget and, in many cases, less capable.
"The United States' extraordinary foundation of global
observations is at great risk," the committee concluded.
Said Brown: "We're seeing a reduction in the development of new
approaches and, in fact, we well could be worse off than we are
now."
_In particular, there is "substantial concern" about the pending
loss of an important satellite-based instrument employed by tropical
weather forecasters and hurricane researchers.
The QuikSCAT information helps scientists estimate wind speeds at
the ocean's surface. That information contributes to year-round
forecasts of marine conditions, and it's crucially important to
hurricane specialists, helping them assess the strength of storms
that are far from land and often enabling the identification of new
tropical systems.
But the device is well past its designed lifetime, which was
expected to end by 2002, and budget concerns and technical
compromises prompted NOAA to replace it with a less sophisticated
instrument that still hasn't been launched, the committee said.
This could diminish the accuracy of hurricane and other
forecasts, especially for coastal areas such as South Florida.
"The committee believes it's imperative that a measurement
capability be available to prevent a data gap," the report
concluded.
Chris Landsea, the National Hurricane Center's science and
operations officer, called QuikSCAT a "wonderful tool" that has
"become ingrained in our operations, and it could disappear
tomorrow."
"What's available in the plans would be a degradation to that,"
Landsea said.
_Much of NASA's budget and many of its scientists are being
diverted to the human space program that was re-energized by
President Bush's proposal to send astronauts back to the moon and
onward to Mars.
The president's 2007 budget reduced NASA's research and analysis
budget for science missions 15 percent compared to 2005. Since 2000,
the agency's earth-science budget has been slashed 30 percent. That
caused the elimination of some projects, including measurements of
solar radiation and Earth radiation that could help scientists
understand global warming.
_In addition, many of NASA's scientists seem too interested in
theoretical research and insufficiently focused on practical science
that can address pressing environmental issues, the committee
said.
In particular, the panel urged NASA scientists to transition from
brief examinations of the climate to sustained studies that might
help answer pressing questions about drought, soil moisture and
other issues.
And, the panel said, coordination between NOAA and NASA is
weak.
"The committee is particularly concerned with the lack of clear
agency responsibility for sustained research programs and the
transitioning of proof-of-concept measurements into sustained
measurement systems," the report said.
At the same time, NOAA is coping with many other problems.
Automated buoys, weather balloons, radars and other equipment fail
at unacceptably high rates, The Miami Herald's "Blind Eye" series
reported in 2005, and budget overruns are legion.
In response to the new report, both agencies issued noncommittal
responses.
"It's useful to have such consolidated and prioritized
information from the users of our data," NOAA Administrator Conrad
C. Lautenbacher said in a written statement. "Once we have a more
complete understanding of this complex study, we will be working
closely with NASA to assess how our two agencies can best address
recommendations."
NASA said it appreciated the group's work and already devotes
considerable resources to earth sciences. "The decadal survey offers
important guidance on how best to spend that money," the agency said
in a prepared statement.
On Capitol Hill, Rep. Bart Gordon, D-Tenn., chairman of the House
Committee on Science and Technology, praised the committee's work as
"a great service in providing clear recommendations for a
constructive way forward."
He said the committee would keep a close eye on NOAA and NASA,
especially when it came to "continued climate observations."
In some ways, the report represented a scientific version of the
Iraq Study Group, which last month issued a comprehensive report
about the war.
Both panels stepped back, closely analyzed a government program
and issued recommendations to set right what once went wrong.
Brown, the University of Miami scientist who participated in the
academy's study, suggested that the group's conclusions should worry
all Americans.
"The simple message is that we've spent decades and what amounts
to billions (of dollars) in developing state-of-the-art
environmental sensing systems from space, and what we're seeing is
that these systems are at risk," he said.
The panel urged federal officials to fully fund currently planned
satellites and design and launch 17 new missions, but it is already
too late to avoid gaps in the U.S. network, he said.
"We might be able to use a foreign satellite capability," Brown
said. "But in the U.S. pipeline, there is no way to fix it quickly.
There's a lag time that's measured in years. These are long-term
decisions that are made."
And now, the consequences are becoming clear.
"To get a report like this through the national academy that even
begins to hint at how screwed up things are is pretty amazing,"
Brown said. "You can tell that feelings are very strong about
this."
