For the first time, NASA scientists have used a shrewd spaceborne detective to track the origin and movement of water vapor throughout Earth's atmosphere.

Scientists using NASA data recently tracked the path and distribution of aerosols -- tiny particles suspended in the air -- to link their region of origin and source type with their tendencies to warm or cool the atmosphere.

NASA researchers have found that tiny atmospheric particles called aerosols can cause a rippling effect on the climate thousands of miles away from their source region.

Many meteorologists and hurricane specialists were forecasting another above average hurricane season for 2006, but it didn't happen, and NASA scientists have learned why.

The official Los Angeles weather station was moved from downtown to the University of Southern California in 1999 and a recent study of comparative data from the previous and new stations show the move resulted in a significant decrease in measured temperatures and precipitation.

A spacecraft fleet will investigate what makes the Northern Lights go wild.
