'Snowball Comets' Are Just Camera Noise, Berkeley Researchers Say After Analyzing Dark Pixels In Iowa Data
Researchers Forrest Mozer and James McFadden of U.C. Berkeley say that instrument noise in a spacecraft's cameras cause the dark pixels that Prof. Louis Frank attributes to small comets bombarding Earth's atmosphere. This investigation is unique in that it uses Frank's own data to refute his theory. (1998-09-08)

MIT Researcher Finds Evidence Of Global Warming On Neptune's Largest Moon
We're not the only ones experiencing global warming. MIT astronomer James Elliot has found evidence that Neptune's moon Triton has warmed up significantly in recent years. Triton's simple, thin atmosphere makes it easier for scientists to study the causes and effects of global warming. (1998-06-24)

Policies Needed For Reporting Potential Hazards Of Asteroid Collisions WithEarth
Some of the thousands of asteroids and comets that will be discovered in future years might initially seem like they're on a collision course with Earth, until further data show otherwise. Astronomers and NASA should develop a plan for communicating information to the public about those that appear to pose a potential hazard to Earth, says a new report from the National Research Council. (1998-05-13)

New Tool To Enhance Weather Forecasters' Skills In Satellite Meteorology, Improve Forecasts Across Africa
Four African meteorologists spent the past nine months at UCAR building a multimedia CD-ROM demonstrating best use of satellite data for improving weather forecasts in the tropics. Better forecasts, including seasonal rainfall predictions, are critical to Africa, where millions depend on the current year's crops. (1998-05-12)

Forecaster Training Makes A Difference In Recent Tornadoes
Over the past year, forecasters in Alabama and Florida--where tornadoes have killed more than 75 people--honed their storm- prediction skills with two training modules released by the University Corporation for Atmospheric Research on CD-ROM. The modules help users to peg storm types in advance based on a blend of weather ingredients. (1998-04-15)
