U.S. to Reposition Satellite Over Amazon

BUENOS AIRES, Argentina — South American meteorologists are getting a boost 
from space: A U.S. weather satellite long used for tracking hurricanes and 
other wild weather will soon be moved over a continent plagued by its own 
costly natural disasters.

In October, the U.S. National Oceanic and Atmospheric Administration plans 
to reposition an aging but reliable 9-year-old satellite high over the 
Brazilian Amazon to provide full-time coverage for forecasters who now 
weather long periods without regular images during U.S. hurricane season.

The satellite _ a sport utility vehicle-sized piece of equipment currently 
hovering about 22,300 miles above the Pacific Ocean _ is part of the 
Geostationary Operational Environmental Satellite (GOES) series, which has 
brought Americans views of Hurricane Katrina, El Nino-fueled storms and 
other meteorological phenomena.

The satellite aid to South America and another that was repositioned in 
2003 to get a better view of Japan are NOAA's contributions to improving 
the Global Earth Observation System of Systems, a coalition of more than 60 
countries working to unify Earth observation by 2015 and improve 
environmental policies around the planet.

"We hope it sets an example for South America and others to share their 
observations to make our total global forecasting work a little better," 
said Gregory Withee, assistant administrator of NOAA Satellites and 
Information Services. "We're all in this together ... because weather is 
global."

The satellites _ the first GOES was launched in the 1970s _ deliver both 
visual and infrared images, and are used to monitor storms, detect sea 
surface temperatures and wildland fires. They also can take cloud 
temperatures, show ozone distribution and track the conditions that can 
produce aircraft icing.

South America has received images from existing GOES-series satellites for 
decades, but those have focused primarily on the United States and its 
immediate surroundings. So whenever a storm kicks up in the Northern 
Hemisphere, the satellite that usually delivers images to South America at 
least every 30 minutes instead rapidly scans the northern trouble spot, 
reducing South American images to as little as once every 3 hours.

During U.S. hurricane season, this happens as much as 40 percent of the 
time, NOAA officials said.

In weather terms, such gaps can be an "eternity," said 1st Lt. Ricardo 
Valenti, who oversees a roomful of Air Force and civilian contractors 
tracking weather at the Argentine National Meteorological Service.

A hailstorm can develop in minutes, taking out a farmer's entire soybean 
crop, he said. An undetected ash cloud, expelled by a volcano during a gap 
in satellite coverage, can stop a jet engine over the Andes.

"We can't monitor what we can't see," Valenti said. "There's no anger. We 
accept that it's like this. But that's why we made the request."

Last year, South American meteorologists formally requested that the 
satellite be repositioned, rather than the more likely scenario of keeping 
it as an in-orbit spare after the launch later this spring of the 13th 
GOES-series satellite, which will continue monitoring U.S. storms.

Argentina and Brazil are the only South American nations with government 
satellites, yet they lack weather forecasting capabilities, said Conrado 
Varotto, executive director of the Argentine National Commission for Space 
Activities. Argentina's only satellite, for example, takes photos for 
agricultural purposes, or assesses damage after disaster strikes, he said.

While Russia, China, Japan and richer nations in Europe have environmental 
satellites, poorer regions can't afford to launch ones as capable as a 
GOES, which costs roughly $400 million to put in orbit _ more than eleven 
times the Argentine space program's annual budget.

"This is important for South America because they need data," NOAA's 
administrator, Vice Adm. Conrad Lautenbacher Jr., told The Associated 
Press. "By having continuous coverage it will help provide warnings in time 
to save lives and protect property."

Latin America has no shortage of natural disasters, and its recovery 
efforts are strapped for cash. The United States donated $1.4 million in 
relief and disaster preparedness to South America in fiscal year 2005, 
according to the Office of Foreign Disaster Assistance.

Flooding and landslides in Venezuela, Guyana and Colombia in February 2005 
killed 100 people and left tens of thousands without homes. In March 2004, 
what some meteorologists considered the first recorded South Atlantic 
hurricane ravaged the southern Brazilian state of Santa Catarina, rendering 
2,000 people homeless. Venezuela's flooding and landslides in 1999, that 
country's worst natural disaster in decades, killed thousands.

The repositioned satellite should help provide more warning of brewing 
storms. But it's a temporary solution. Similar satellites have broken down 
unexpectedly within two years of launch, and most have been retired after 
10 years. Although the satellite destined for South America still works 
perfectly and has 11 more years of fuel, it was launched in 1997 and its 
life span is unpredictable.

Additionally, the U.S. still owns the satellite and it is subject to being 
moved in case another satellite fails. Still, Varotto is grateful for the 
satellite and NOAA's plans to shoulder the "minimal" cost of maintaining it 
in orbit.

"This is a typical win-win situation. For the U.S., it isn't costing them a 
cent more," Varotto said, "but from the point of view of the benefits to 
South America, it's as if the United States made the decision to earmark 
millions of dollars for the region."
