NOAA's GOES-15 Weather Satellite Captures Its First Image of Earth

GOES-15, launched on March 4 from Cape Canaveral, Florida, joins three other NOAA operational GOES spacecraft that help the agency's forecasters track life-threatening weather—from tornadoes, floods and hurricanes—and solar activity that can impact the satellite-based electronics and communications industry. The black and white full-disk image shows North and South America with a storm system visible across the United States, indicated by a drape of clouds from New England westward to the central Plains. Further west is a cold front over the Rocky Mountains. Mostly clear skies are seen over the mid-Atlantic, southeastern U.S., Gulf of Mexico, California and Mexico. (More)

Norfolk, Va.-based NOAA Ship Thomas Jefferson to Map Ocean Floor in Gulf of Mexico

Commerce’s NOAA Ship Thomas Jefferson, one of the most technologically advanced hydrographic survey vessels in the world, will depart its Norfolk, Va. homeport on April 6 to conduct a five-month long effort to map the seafloor and look for hazards to navigation off the Gulf coast. “The Gulf of Mexico has been affected by a number of large hurricanes in recent years, and our work will pinpoint the resulting hazards and shoals in these busy waters,” said Cmdr. Shepard Smith, Thomas Jefferson’s commanding officer. (More)

50th Anniversary of the Satellite that "Forever Changed Weather Forecasting"

One of the first satellite images. Click for a full version.

Fifty years ago today, the world’s first weather satellite lifted off from Cape Canaveral, Fla., and opened a new and exciting dimension in weather forecasting. Top leaders from Commerce’s NOAA and NASA hailed the milestone as an example of their agencies’ strong partnership and commitment to flying the best satellites today and beyond. The first image from the satellite, known as TIROS-1, was a fuzzy picture of thick bands and clusters of clouds over the United States. An image captured a few days later revealed a typhoon about 1,000 miles east of Australia. TIROS-1, a polar-orbiting satellite, weighed 270 pounds and carried two cameras and two video recorders.

NOAA: Sixth-Warmest February in Combined Global Surface Temperature, Fifth-Warmest December-February

Last month’s combined global land and ocean surface temperature made it the sixth-warmest February ever recorded. Additionally, the December 2009-February 2010 period was the fifth-warmest on record averaged for any similar three-month Northern Hemisphere winter-Southern Hemisphere summer season, according to scientists at NOAA’s National Climatic Data Center in Asheville, N.C. Based on records going back to 1880, the monthly NCDC analysis is part of the suite of climate services NOAA provides to businesses, communities and governments so they may make informed decisions to safeguard their social and economic well-being.

NOAA: Imminent Flood Threat in Midwest, South and East at Risk

Major flooding has begun and is forecast to continue through spring in parts of the Midwest according to NOAA’s National Weather Service. The South and East are also more susceptible to flooding as an El Niño influenced winter left the area soggier than usual. Overall, more than a third of the contiguous United States has an above average flood risk—with the highest threat in the Dakotas, Minnesota and Iowa, including along the Red River Valley where crests could approach the record levels set just last year.

FEMA and NOAA Renew Partnership to Encourage Flood Safety

As one of the snowiest winter seasons in many years yields to warmer weather and the promise of rain and snowmelt, the Federal Emergency Management Agency’s (FEMA) FloodSmart campaign and Commerce’s National Oceanic and Atmospheric Administration (NOAA) announced they are again working together during Flood Safety Awareness Week (March 15-19) to raise awareness of the dangers associated with flooding and steps to protect against damage.

Commerce’s National Oceanic and Atmospheric Administration (NOAA) reports that temperatures were below normal for the contiguous U.S. for the winter season (December through February). The winter season was wetter than normal; however precipitation in February alone was slightly below average. Based on data going back to 1895, the monthly analyses are prepared by scientists at NOAA’s National Climatic Data Center in Asheville, N.C.

Commerce’s National Oceanic and Atmospheric Administration (NOAA) and NASA officials announced a new Geostationary Operational Environmental Satellite (GOES), launched tonight, successfully reached its initial orbit, joining four other GOES spacecraft that help NOAA forecasters track life-threatening weather and solar activity. “Our geostationary satellites are the nation’s weather sentinels in the sky,” said Jane Lubchenco, Ph.D., Under Secretary of Commerce for Oceans and Atmosphere and NOAA administrator. “With more than 35 million Americans living in hurricane prone areas and more than 1,000 tornadoes touching down in the U.S. annually, we need the reliable, accurate data that these satellites provide.” (More) (Launch image)

NOAA National Weather Service to Use New Hurricane Wind Scale

NOAA’s National Weather Service will use a new hurricane scale this season called the Saffir-Simpson Hurricane Wind Scale. The scale keeps the same wind speed ranges as the original Saffir-Simpson Scale for each of the five hurricane categories, but no longer ties specific storm surge and flooding effects to each category. Changes were made to the Saffir-Simpson Scale because storm surge values and associated flooding are dependent on a combination of the storm’s intensity, size, motion and barometric pressure, as well as the depth of the near-shore waters and local topographical features.

Individuals and decision-makers across widely diverse sectors—from agriculture energy to transportation—increasingly are asking Commerce’s National Oceanic and Atmospheric Administration (NOAA) for information about climate change in order to make the best choices for their families, communities and businesses. To meet the rising tide of these requests, U.S. Commerce Secretary Gary Locke today announced the intent to create a NOAA Climate Service line office dedicated to bringing together the agency’s strong climate science and service delivery capabilities.
